Alonso Zaragoza and Jadhira Sanchez filed the complaint on August 21, 2026, in the U.S. District Court for the Northern District of Illinois against Taylor Fresh Foods Inc. and Taylor Farms California Inc. The lawsuit alleges that contaminated shredded iceberg lettuce caused Zaragoza’s illness after he ate a July 11 Taco Bell meal.

The case is pending. Its allegations have not been proven in court, and the filing does not establish that the defendants caused Zaragoza’s illness.

What the Chicago lawsuit alleges

According to the complaint and Chicago Sun-Times reporting, Zaragoza ordered a Chalupa Supreme box meal at a Northwest Side Taco Bell on July 11. The meal contained fresh shredded iceberg lettuce, the lawsuit says.

The complaint says Zaragoza’s symptoms intensified over the following days. By July 13, he was sweaty, feverish and dizzy and had to leave work, according to the filing. He went to the emergency room at Northwestern Memorial Hospital on July 15, the Sun-Times reported.

Zaragoza told the newspaper that he lost about 20 pounds in a month and continued to experience low energy, pain and a reduced appetite while recovering. According to the complaint, he was not tested for a parasite until a third clinic visit on July 26, and the positive result came back August 4.

Sanchez, who did not become ill, is also a plaintiff. The lawsuit seeks damages for alleged pain and suffering, medical expenses, missed work and other losses. It also claims Sanchez lost sleep, altered the household diet to accommodate Zaragoza’s nearly all-liquid diet and took time away from work and personal obligations to care for him.

FDA investigation remains ongoing

The FDA says its investigation concerns a multistate outbreak of Cyclospora infections linked to iceberg lettuce sourced from central Mexico and recalled by Taylor Farms de Mexico.

In its current update dated August 27, the FDA reported 11,458 illnesses in 20 states, 495 hospitalizations and two deaths. Illinois is among the states with reported cases. The agency said inspections and sampling at iceberg lettuce growers and a processing facility in Mexico remain ongoing.

The FDA says Taylor Farms de Mexico began voluntarily removing the affected iceberg lettuce from the U.S. market on July 17. The recall includes food-service products and certain Marketside salad and shredded-lettuce products with specified best-by dates. The FDA says recalled product should no longer be available, and Taco Bell has indicated it stopped using lettuce from Taylor Farms de Mexico as of July 17.

FDA records confirm that recalled iceberg lettuce was distributed to Illinois. That finding does not by itself establish that the lettuce served in Zaragoza’s Chicago meal was recalled product or that it caused his illness. Those questions are part of the lawsuit’s unresolved allegations and the broader public-health investigation.

What Chicago residents should do

The FDA says Cyclospora infection commonly causes diarrhea, loss of appetite, weight loss, stomach cramps or pain, bloating, increased gas, nausea and fatigue. Fever, vomiting, body aches and headaches may also occur, and some infected people have no symptoms. Symptoms can relapse, and untreated illness can lead to dehydration and serious complications.

Chicago residents who develop symptoms should contact a health care provider, especially if they ate shredded iceberg lettuce during the two weeks before becoming ill. The FDA also advises people who previously purchased or received recalled lettuce to carefully clean and sanitize surfaces or containers the food touched and to follow its food-safety and cleaning guidance.

The Chicago lawsuit and the FDA investigation remain unresolved. Residents should use current FDA recall information and consult a health care provider for medical concerns, rather than treating allegations in the complaint as final findings.

• FDA Cyclospora outbreak investigation
• Chicago Sun-Times report

Federal health officials reported 495 hospitalizations and two deaths in the outbreak. The deaths occurred in Michigan; an earlier FDA update said both patients had significant underlying health conditions that may have been worsened by cyclosporiasis and dehydration.

The update matters for people who may have eaten recalled lettuce even though the FDA said it remains confident that iceberg lettuce tied to this specific outbreak is no longer on the market.

What changed in the latest update

The August 27 totals rose from 10,930 illnesses in 17 states listed in the August 20 update. Georgia, Tennessee and Texas were the three newly added states.

The 20 states with reported outbreak cases are Arkansas, Georgia, Iowa, Illinois, Indiana, Kansas, Kentucky, Massachusetts, Maine, Michigan, Missouri, Nebraska, New Hampshire, North Carolina, Ohio, Oklahoma, Pennsylvania, Tennessee, Texas and West Virginia.

The last reported illness onset date in the FDA update was August 15, 2026. That date and the additional cases do not necessarily mean recalled lettuce remains available for purchase. Most illnesses began before the July 17 recall, and public-health investigations can add confirmed cases after a suspected food has been removed from the market.

What officials are investigating

Federal officials have linked the outbreak to recalled iceberg lettuce sourced from central Mexico and associated with Taylor Farms de Mexico. FDA inspections and sampling at iceberg lettuce growers and a processing facility in Mexico remain underway in coordination with Mexican authorities.

The investigation remains open. The agencies have described epidemiological and traceback evidence connecting the outbreak to the recalled lettuce, but the August 27 update does not identify a completed contamination mechanism or report that the lettuce itself tested positive.

The FDA recall notice includes Marketside retail products sold at select Walmart stores, including 12- and 24-ounce Iceberg Salad and 8- and 16-ounce Shredded Lettuce with best-by dates from July 18 through August 3, 2026. The notice also lists a broader range of food-service products, brands, lot information and dates.

FDA separately lists states where distribution of recalled products was confirmed and states where products may have been distributed further. Those distribution lists are not the same as the 20 states reporting confirmed outbreak cases.

What consumers should do

Do not eat any recalled lettuce. If you still have a recalled product, throw it away and clean and sanitize refrigerators, cutting boards, containers, counters and other surfaces it may have touched.

Cyclospora can cause watery diarrhea, frequent bowel movements, loss of appetite, weight loss, stomach cramps, bloating, increased gas, nausea and fatigue. Symptoms usually begin about one week after infection but can start as soon as two days or more than two weeks later. Without treatment, symptoms can last from a few days to a month or longer and may return after appearing to improve.

People who develop symptoms after eating recalled lettuce should contact a health care provider and stay hydrated. Patients may need to specifically request testing for Cyclospora because routine stool tests do not always screen for the parasite.

CDC also cautions that other Cyclospora illnesses and unrelated outbreaks are under investigation nationally. Not every Cyclospora infection in the United States is linked to the recalled Taylor Farms lettuce.

FDA inspections and sampling in Mexico continue, so the case count and agency guidance may change as investigators review additional information.

The immediate consumer point is that recalled Taylor Farms de Mexico iceberg lettuce should no longer be available in North Carolina stores or restaurants. The U.S. Food and Drug Administration says the product’s best-by dates have passed.

What changed in the federal investigation

North Carolina was added to the multistate investigation in the federal update issued Aug. 5. In an Aug. 13 update, the FDA and Centers for Disease Control and Prevention reported 9,481 laboratory-confirmed illnesses, 398 hospitalizations and two deaths across 17 states.

The investigation remains open. Federal officials said most illnesses began before Taylor Farms de Mexico recalled the lettuce on July 17. Additional cases may still be added because it can take as long as six weeks to determine whether a patient’s illness is part of the outbreak.

The FDA and CDC identify iceberg lettuce sourced from central Mexico and recalled by Taylor Farms de Mexico as the source of the ongoing multistate outbreak. That determination is based on epidemiological information and traceback work. FDA records say there are no confirmed positive product-test results for Cyclospora, and the investigation continues.

Recalled lettuce was distributed to North Carolina food-service customers

FDA records show recalled iceberg lettuce products distributed by Taylor Fresh Foods through food-service channels in North Carolina from June 29 through July 16. The recalled products included food-service lettuce supplied to restaurants and other customers.

The recall also covered certain Marketside salad and shredded-lettuce products sold at select Walmart stores in other states. The FDA and CDC say the affected best-by dates have passed and recalled lettuce should no longer be on sale or in restaurants.

Consumers who previously received recalled lettuce should not eat it. They should carefully clean and sanitize surfaces and containers the product touched. Restaurants and retailers should follow federal food-safety guidance and cooperate with health officials if contacted.

North Carolina’s case increase is broader than the federal outbreak

The federal outbreak count should not be treated as the total number of North Carolina cases. The North Carolina Department of Health and Human Services dashboard reported 906 cases since May 2026 and 31 hospitalizations as of Aug. 11. Wake County residents accounted for 508 of those cases.

NCDHHS uses a state reporting methodology that includes cases identified through positive laboratory testing or through compatible illness and a known exposure. Federal officials are reporting laboratory-confirmed cases for the multistate investigation, so the figures are not directly interchangeable.

NCDHHS said it is working with state and local partners to identify the source of the broader increase. The agency said the North Carolina increase does not currently appear associated with the earlier Taco Bell-linked outbreak. Recent North Carolina patients reported eating parsley and cilantro more often than expected, but NCDHHS has not identified either food as a confirmed source.

Residents should not assume that lettuce, parsley, cilantro or any other single food caused the statewide increase. The CDC also says it is investigating other national cyclosporiasis illnesses and outbreaks that may be unrelated to the recalled-lettuce outbreak.

Symptoms can last weeks or return

Common symptoms of cyclosporiasis include watery or frequent diarrhea, loss of appetite, weight loss, stomach cramps, bloating, increased gas, nausea and fatigue. Symptoms may improve and then return, and untreated illness can last a month or longer.

People with persistent or recurring diarrhea should contact a health care provider and ask whether Cyclospora-specific testing is appropriate. Routine stool tests do not always screen for the parasite. Staying hydrated is important because diarrhea can cause dehydration and more serious complications. People with dehydration concerns, prolonged illness or compromised immune systems should seek medical care.

What happens next

The FDA has begun an on-site inspection and sampling at Taylor Farms de Mexico in coordination with Mexican officials. Federal, state and local health agencies are continuing case interviews, traceback work and updates to distribution and illness information.

For North Carolina residents, two investigations need to be kept separate: the federal lettuce-linked outbreak that includes the state, and the larger state increase whose single source remains unknown.

The agency also identified a Taylor Farms de Mexico recall of iceberg lettuce connected to the investigation. The product’s listed distribution footprint includes Alabama, Florida, Georgia, Kentucky, North Carolina, South Carolina, Tennessee and Virginia.

The development puts a widely used restaurant ingredient at the center of an active food-safety investigation while prices are already rising. It affects the decisions of consumers and food businesses, but the FDA’s identification of iceberg lettuce is not a finding that every iceberg lettuce product or every restaurant is implicated.

What the FDA identified

The FDA’s update says iceberg lettuce is the leading food item of interest in the Cyclospora investigation. That designation is based on information gathered through interviews with sick people. It focuses the agency’s inquiry on a food item without amounting to a final determination about the cause of every illness or the responsibility of any restaurant or other business.

The update also points to the Taylor Farms de Mexico recall and identifies eight states in the product’s distribution footprint. The states are concentrated in the Southeast and neighboring regions: Alabama, Florida, Georgia, Kentucky, North Carolina, South Carolina, Tennessee and Virginia.

The listed footprint does not mean that all iceberg lettuce sold nationwide was recalled. It also does not establish that all products sold in those states were affected. Consumers and food businesses can follow the FDA’s current food-safety alerts, recalls and outbreak advisories for product and distribution updates.

The FDA investigation page says the outbreak involved illnesses reported after the investigation began in July. The agency’s update does not establish a final number of illnesses in the investigation.

Rising lettuce costs add pressure

The food-safety concern comes as lettuce supplies and prices have become another challenge for restaurants. The Associated Press reported that hot weather in Arizona affected lettuce supplies during the first half of 2026.

AP also reported that the retail price of iceberg lettuce rose nearly 20% between January and June. For restaurants that use lettuce heavily in salads, sandwiches or other menu items, the combination of a recall-related investigation and higher ingredient costs can complicate purchasing and menu planning.

The available reporting does not quantify the overall financial effect on the restaurant industry. It does show why the FDA’s identification of iceberg lettuce matters beyond the investigation itself: businesses must pay attention to food-safety information while managing an ingredient whose price has risen sharply in a short period.

What businesses and consumers should watch

The investigation does not establish that a restaurant chain caused the illnesses. Sweetgreen, which operates 285 U.S. locations, said its food had not been connected to the Cyclospora outbreak. The company had not confirmed a sales decline related to the investigation, according to AP.

For food businesses, the immediate issue is tracking the FDA’s alerts and recall information alongside the distribution states identified in the investigation. For consumers, the agency’s food-safety information remains the place to check for updates about affected products and advisories.

The next public development will come through updates to the FDA’s ongoing investigation and its food-safety notices. For now, the agency has identified iceberg lettuce as the leading food item of interest, tied the inquiry to a Taylor Farms de Mexico recall, and listed distribution across eight states. Those facts narrow the focus of the investigation without turning it into a blanket finding against every lettuce product, restaurant or seller.

Taylor Farms de Mexico announced a voluntary removal of iceberg lettuce sourced from central Mexico from the U.S. market on July 17, 2026. The action includes Marketside iceberg salad in 12-ounce and 24-ounce packages and shredded lettuce in 8-ounce and 16-ounce packages. The listed best-if-used-by dates run from July 18 through Aug. 3, 2026.

The recalled products were sold through Walmart and distributed to food-service customers nationwide, according to the FDA’s outbreak investigation. The agency has advised consumers not to eat the recalled lettuce.

What the FDA has traced

FDA traceback work identified Taylor Farms de Mexico as the common supplier of shredded iceberg lettuce used at Taco Bell locations where ill people had eaten. Traceback is a supply-chain finding; it identifies a shared source for the food under review but does not by itself establish that every product from the supplier was contaminated or that the lettuce definitively caused every reported illness.

The investigation concerns Cyclospora illnesses reported across nine states. The FDA has not provided a final total number of illnesses in the update, and the agency’s findings remain subject to additional investigation and testing.

Taylor Fresh Foods is also identified in the federal food-safety information associated with the recall. The public notices describe the products, supplier and distribution channels involved in the action, while the investigation continues to determine the scope of any additional products or locations that may require action.

Testing and consumer guidance

As of July 19, the FDA reported no confirmed positive product-test results for Cyclospora. State and federal partners were continuing to collect and analyze samples.

The absence of a confirmed positive product sample does not end the investigation. The agency’s traceback findings and the illnesses under review are being evaluated alongside laboratory testing and other information gathered by state and federal health officials.

Consumers who have lettuce matching the recalled descriptions and dates should not eat it. They should check the package size, product description and best-if-used-by date before using the lettuce. The FDA’s safety-information notices provide the active federal updates connected to the recall and outbreak investigation.

The recall matters beyond individual households because the products entered both retail and food-service channels. A product still in a refrigerator can present a separate consumer-safety question from lettuce that was served at a restaurant, while the distribution investigation may determine whether additional products, retailers or food-service locations need to take action.

What happens next

FDA and its state and federal partners are continuing to analyze samples and investigate the outbreak. The next significant developments are expected to include any confirmed product-test results, a clearer count of illnesses and a determination of whether the recall needs to expand.

For now, the agency’s public guidance is limited to the identified recalled lettuce: consumers should not eat it, and the investigation remains ongoing.

The disputed sample was not part of Taylor Farms’ lettuce recall, according to reporting by The Associated Press. Investigators have not said that the recalled produce caused every reported illness, and they have not established a direct biological connection between the recalled product and all cases under investigation.

The investigation remains active across multiple states and restaurant supply chains. FDA and CDC figures cited by AP show at least 1,645 reported U.S. cyclospora illnesses in 2026, including 141 hospitalizations.

What investigators know

Federal officials remain focused on Taylor Farms lettuce as one possible outbreak source. That focus is part of an ongoing traceback investigation, not a final finding that the company’s lettuce caused the full outbreak.

The investigation changed after a sample from Taylor Farms that was initially reported as positive was later treated as inaccurate. The sample was also outside the company’s lettuce recall. That means the test result cannot be used as proof that the recalled product was contaminated or that it explains all of the illnesses reported in the outbreak.

Officials have not yet resolved the precise contaminated product or the complete path through the supply chain. The available reporting also does not establish a direct biological link between recalled produce and every illness. Those unresolved questions are central to determining whether a specific product, supplier or distribution pathway can be identified.

Why the investigation matters

Cyclospora illnesses can affect consumers in different states even when the suspected food source entered restaurants or stores through a shared supply chain. In this investigation, the involvement of restaurant supply chains means the traceback work extends beyond a single location or individual food-service operation.

The reported illness total and hospitalizations show the public-health stakes of identifying the source. At least 1,645 U.S. illnesses and 141 hospitalizations had been counted in 2026 at the time of AP’s July 27 report. The total may change as health departments receive, confirm or revise reports.

For consumers, retailers and restaurants, the immediate practical question is whether officials identify a product that requires a recall or other warning. Until the source chain is resolved, businesses and the public remain dependent on formal recall guidance and notices from public-health authorities rather than on the disputed test alone.

What happens next

FDA, CDC and state investigators are expected to continue tracing lettuce through the relevant supply chains and comparing illness reports with product information and laboratory findings. The next significant development would be a confirmed source, a new recall or an official consumer warning.

The FDA maintains its public alerts, advisories and safety information page as the official location for current food-safety recalls and outbreak-related notices. The approved reporting packet did not identify a new FDA or CDC outbreak update dated Aug. 7 or Aug. 8, 2026. The strongest available account was AP’s report published July 27.

For now, the investigation points to Taylor Farms lettuce as a possible source, while the inaccurate test result and the absence of a confirmed connection to every illness leave the broader source unresolved.

The development, reported August 5, 2026, broadens a food-safety investigation affecting restaurants, produce suppliers and distributors. The FDA and CDC have not established every affected product or finalized how the contamination occurred, so the lettuce is being described as linked or potentially linked while the inquiry continues.

The investigation has immediate implications for restaurants and food-service businesses that received or served the lettuce, as well as consumers trying to determine whether a meal may have involved a recalled ingredient. Federal officials have not said that all Taylor Farms products or all restaurant lettuce is contaminated.

What federal officials are investigating

The FDA and CDC are investigating illnesses associated with iceberg lettuce from central Mexico. Taylor Farms de Mexico voluntarily recalled implicated iceberg lettuce as the investigation proceeded.

FDA information released in July identified restaurant-served shredded iceberg lettuce as part of the inquiry. That initial restaurant-linked investigation covered Taco Bell locations in Indiana, Kentucky, Michigan, Ohio and West Virginia, making five states at that stage.

The FDA’s investigation listed illness onset dates ranging from June 22 through July 20, 2026. The later update reported by The Associated Press connected the outbreak to 15 states as of August 5.

AP also reported that an earlier CDC update linked at least 1,645 illnesses and 141 hospitalizations to the outbreak, while federal officials were investigating thousands of additional reports. Those figures were part of an earlier update and do not represent a final count for the investigation.

Why the source remains unsettled

Federal officials are focusing on the recalled lettuce and restaurant distribution, but the investigation has not conclusively established the full contamination pathway. The FDA has characterized the lettuce as linked or potentially linked rather than declaring that it caused every reported illness.

A lettuce sample initially reported as positive was later described by the FDA as a false positive. That finding does not, by itself, resolve the broader epidemiological investigation, which includes illness reports, distribution information and additional evidence being reviewed by officials.

The distinction matters for restaurants, distributors and consumers. A product recall can identify a specific supply concern without showing that every item from a company, every location of a restaurant chain or every serving of lettuce is affected. The available federal information does not establish that Taylor Farms or Taco Bell caused every illness.

What happens next

The recall and federal investigation remain active. Officials still need to determine which products and distribution channels were affected and how the contamination may have occurred.

For the food-service industry, the investigation puts attention on supply-chain records connecting produce suppliers, distributors and restaurants. The FDA’s initial information identified shredded iceberg lettuce served at certain Taco Bell locations, while the broader update focused on a 15-state outbreak and recalled lettuce from central Mexico.

For the public, the most important verified change is the expansion in the outbreak’s known geographic scope—not a final determination that all restaurant lettuce or all products from the supplier are unsafe. The illness total, the list of affected products and the contamination pathway may change as federal officials continue their work.

The Associated Press reported the revised test information on July 19, 2026, citing statements from the company and health authorities. The sample was not part of Taylor Farms’ lettuce recall, according to AP’s account. The company’s voluntary recall nevertheless remained in place as the investigation continued.

The development does not establish that Taco Bell food caused the illnesses, nor does it show that Taylor Farms lettuce was contaminated. Authorities were still investigating the source of the outbreak and had not declared it solved.

What investigators know

Federal and state health authorities were examining a rise in cyclospora illnesses across multiple U.S. states. The investigation involved the U.S. Food and Drug Administration, the Centers for Disease Control and Prevention, state health authorities, Taco Bell and Taylor Farms.

Initial reporting linked the illnesses to lettuce served at Taco Bell locations. That link was weakened after a Taylor Farms sample that initially appeared positive was later reported to have produced a false-positive result. AP said the sample was separate from the product covered by the company’s voluntary recall.

At the time of AP’s report, at least 1,645 U.S. illnesses and 141 hospitalizations had been reported in 2026. The source packet notes that reports differed on the total case count and timing, so those figures should be understood as the count AP cited at that point rather than a final outbreak total.

No confirmed positive product test had been identified in the cited reporting. That distinction is important: an epidemiological connection involving restaurants or a supplier can guide an investigation, but the reporting reviewed did not establish that a specific product was contaminated.

Restaurant impact

The investigation also created a measurable, though limited, change in Taco Bell traffic. Axios reported that visits to the chain on July 9, 10 and 11 were below comparable early-July averages, based on Placer.ai data.

The reported declines were 0.9% on July 9, 4.6% on July 10 and 5.8% on July 11. The figures show how an unresolved food-safety investigation can affect a national restaurant chain while authorities are still working to determine whether a particular ingredient or product is involved.

They do not, by themselves, demonstrate that customers avoided Taco Bell because of the investigation or prove that the chain caused any illness. The data provide a restaurant-traffic comparison, not a finding about the outbreak’s source.

What happens next

The FDA and state authorities were continuing to investigate the illnesses and the possible role of the lettuce supplier. Taylor Farms’ voluntary recall remained in place in the reporting reviewed, even as the initially positive sample was described as a false positive.

The next significant development would be confirmation of a contaminated product, a revised case count from federal or state health authorities, or a decision to change the recall. None of those outcomes had been reported in the approved coverage. Until investigators identify a confirmed source, consumers, restaurants and suppliers are left with an unresolved link rather than a final finding.

The episode illustrates the uncertainty of outbreak tracing. A preliminary test can redirect attention, but a later test result may remove what appeared to be direct product evidence. In this case, the false-positive account changed the evidentiary picture without ending the broader investigation.

Two days later, the U.S. Food and Drug Administration said a test associated with Taylor Farms was a false positive. The agency also said the result did not end or change the broader investigation, leaving the final source of the outbreak unresolved.

What the companies did

Taylor Farms, a major food supplier, and Sysco, a major distributor, removed the iceberg lettuce from their supply chains as a precaution while the investigation proceeded. The lettuce had been sourced from central Mexico and moved through U.S. food-service and restaurant networks.

The withdrawals show how a food-safety investigation can quickly cross borders even when the immediate public-health inquiry is centered in the United States. Mexican agricultural supply was connected to U.S. distributors, restaurant customers and other food-service buyers, making traceability and timely communication central concerns for companies handling the product.

The available reports do not establish how much lettuce was withdrawn or provide a complete list of downstream buyers. They also do not establish the final outbreak source or the total number of illnesses.

FDA test result did not close the case

In an update reported July 19, Reuters said the FDA determined that a lettuce test linked to Taylor Farms was a false positive. Taylor Fresh Foods said it had been told about the FDA error.

That finding narrowed the significance of the particular test, but it did not clear every supplier, product or shipment connected to the investigation. The FDA said the broader cyclospora inquiry was continuing. The result also should not be read as evidence that all iceberg lettuce from Mexico was unsafe.

Taylor Farms said its branded salads and kits were not associated with the outbreak and did not contain the implicated iceberg lettuce. That statement describes the company’s position about its products; it does not resolve the wider investigation.

Restaurant customers report no effect

Wendy’s and Chipotle said their products were not affected, according to the Reuters reporting. Their statements indicate that the withdrawals did not apply across every restaurant supply chain, although the available sources do not provide a full accounting of affected or unaffected buyers.

For restaurants and food-service companies, the episode underscores the practical stakes of identifying the origin and distribution path of a potentially implicated ingredient. A supplier withdrawal can affect purchasing, menu planning, inventory handling and customer communications even before investigators determine whether a particular product caused illnesses.

For consumers, the central distinction is between precautionary supply-chain action and a confirmed finding. Taylor Farms and Sysco removed the lettuce while the investigation was underway; the sources do not say that Taylor Farms-branded salads caused the outbreak, and the FDA’s false-positive finding did not settle the overall case.

What happens next

The FDA’s investigation remains the next known step. Authorities still need to determine the outbreak’s source and establish the total number of illnesses, while companies and regulators continue working through product traceability and the scope of any affected distribution.

Until that work is complete, the July 17 withdrawals and the July 19 FDA update provide different pieces of the same developing story: a cross-border food-supply response was taken, one test was later identified as a false positive, and the broader U.S. cyclospora investigation remained open.

The FDA’s outbreak reference is 1390. The agency’s available summary does not provide a complete final case count, so the size of the outbreak cannot be stated from the approved information. The investigation also remains active, meaning additional products, suppliers or cases could be identified after the July 24 update.

What the recall involves

The recall concerns iceberg lettuce sourced from central Mexico and distributed in the United States. The FDA identifies Taylor Farms de Mexico in Guanajuato, Mexico, as the source location described in the recall notice.

Taylor Fresh Foods said it removed the lettuce voluntarily from the U.S. market because of the possible health risk. That wording is important: the available information describes possible Cyclospora contamination, not a finding that every Taylor Farms lettuce product is contaminated.

The recall action has practical consequences across the food chain. Restaurants, food-service distributors and grocery retailers may handle products covered by the market action, while consumers may encounter affected lettuce through those channels. The approved recall information does not establish that restaurants nationwide served contaminated lettuce, and it does not identify every business or product involved.

What Cyclospora can cause

Cyclospora infection commonly causes diarrhea and frequent bowel movements. The FDA’s investigation is examining a possible connection between those illnesses and iceberg lettuce, but the available summary does not support treating the possible contamination as confirmed illness causation for every person who consumed lettuce.

For consumers, the central issue is whether lettuce in their possession or on a menu is covered by the recall. The FDA’s recall notice and recall index contain the official market-action information. The packet does not include product codes, package sizes, retail locations or use-by dates, so those details cannot be added here.

Why the investigation is still developing

Foodborne-illness investigations often involve several stages of traceback. In this case, the FDA said the July 24 update included additional case information and ongoing traceback activity. That work is intended to clarify how the implicated lettuce moved through the supply chain and whether other products or suppliers require review.

The FDA’s recall index lists the July 18 iceberg-lettuce recall along with related Cyclospora entries. The timing shows a sequence of actions rather than a final resolution: Taylor Fresh Foods announced the removal on July 18, and the FDA updated the outbreak investigation six days later on July 24.

No final case count is provided in the available FDA summary, and the agency may identify additional cases or products as the investigation proceeds. The next known step is continued FDA traceback and review of additional case information. Until that work is complete, the supported conclusion is limited to a possible contamination risk involving specified iceberg lettuce sourced from central Mexico, not all lettuce from the company or all lettuce sold in the United States.

The August 3 CDC update linked the outbreak epidemiologically to iceberg lettuce. The FDA says patient interviews, ingredient-level analysis and traceback continue to converge on shredded iceberg lettuce supplied by Taylor Farms de Mexico. But the agency also says a lettuce sample initially reported as positive was later determined to be a false positive, and that no confirmed positive product sample remained as of July 19.

That leaves consumers with a specific recall to check—not a warning against all iceberg lettuce, all Taylor Farms products or all lettuce from Mexico—and regulators with a broader supply-chain question: how should officials act when illness and traceback evidence are strong but laboratory confirmation in a retained product sample is unavailable?

What changed on August 3

The CDC said the investigation is open and involves Illinois, Indiana, Kansas, Kentucky, Michigan, Ohio, Oklahoma, Pennsylvania and West Virginia. Those are the nine states with outbreak cases; they are not the full list of states where recalled products were distributed.

CDC’s notice separately says it is aware of two cyclosporiasis-related deaths in Michigan involving people with underlying health conditions and that it will update its website to include confirmed deaths. At the same time, the page’s fast-facts block still displays zero deaths. The figures should therefore be attributed precisely: CDC has reported two Michigan deaths as part of the outbreak, while its current case-count block has not yet incorporated them.

How investigators narrowed the source

FDA and CDC investigators found a common exposure pattern among people who reported eating at Taco Bell locations. FDA’s July 17 update said traceback converged on a single supplier, Taylor Farms de Mexico, which provided shredded iceberg lettuce used by Taco Bell locations where sick people ate.

Taylor Farms initiated a recall or market removal on July 17 for iceberg lettuce sourced from central Mexico. The action was broader than the original restaurant connection because the lettuce moved through food-service and retail channels. CDC says recalled products were distributed and sold to consumers, restaurants and retailers in at least 27 states. FDA’s distribution list names food-service shipments in 28 states and separately lists select Walmart retail sales in 15 states, while warning that the reach could expand as the investigation continues.

The Taco Bell connection remains specific: reported exposure at Taco Bell locations helped investigators identify a common ingredient. It does not mean that every recalled product was sold by Taco Bell or that every illness in the nine-state investigation came from a single restaurant chain.

Which retail products are included

FDA’s investigation notice identifies Marketside products sold at select Walmart stores: Iceberg Salad in 12-ounce and 24-ounce packages with best-if-used-by dates from July 18, 2026, through August 3, 2026, and Shredded Lettuce in 8-ounce and 16-ounce packages with dates from July 18 through August 3, 2026. The FDA recall notice also lists numerous food-service products, lot information and additional brands.

Consumers should compare the product name, package size, date and other details in the FDA notice. Do not assume that a Walmart purchase, a Taylor Farms label or an iceberg-lettuce ingredient alone is enough to identify a recalled product.

If a package matches the recall, do not eat it or taste it. Discard it or return it to the place of purchase for a refund. Wash and sanitize refrigerators, cutting boards, containers and other surfaces that touched the recalled lettuce.

The testing gap

FDA is not describing the recalled lettuce as laboratory-confirmed contaminated. The agency said a sample collected at the border and initially reported as positive did not represent true amplification and was a false positive. As of July 19, FDA said it had no confirmed positive product samples for Cyclospora.

That testing result did not end the investigation or cancel the recall. FDA said the false-positive finding did not change the epidemiological evidence supporting the voluntary recall, and that traceback and outbreak data continued to converge on shredded iceberg lettuce from Taylor Farms sourced from growers in central Mexico.

The unresolved questions are more specific: investigators have not publicly identified the farm-level source or explained exactly how contamination occurred. They also have not said whether additional products, restaurants, retailers or distribution channels will be added before the investigation closes.

What consumers and businesses should do

Households, restaurants and retailers that purchased or received recalled iceberg lettuce should remove it from use immediately. Businesses should check inventory and supplier records against the product-specific FDA recall notice rather than relying only on a brand or restaurant name.

People with persistent watery diarrhea, fatigue, loss of appetite, weight loss, cramping or related symptoms should contact a health-care provider and mention possible Cyclospora exposure, particularly if they ate shredded iceberg lettuce in the two weeks before becoming ill. Routine stool tests do not always screen for Cyclospora, so patients may need to ask about specific testing.

The immediate public-health warning is narrow and practical: follow the listed recall details, discard or return matching products, and clean surfaces they touched. The accountability issue is broader. Fresh produce can move through growers, importers, processors, distributors, restaurants and retailers before an illness pattern is recognized. This investigation shows how officials may need to remove a product based on converging epidemiological and traceback evidence even when a laboratory-confirmed contaminated package is never found.

• FDA: Investigation of 9-state Cyclospora outbreak linked to iceberg lettuce
• CBS News: Cyclospora outbreak traced to lettuce used by Taco Bell
• Associated Press: Cyclospora outbreak cases linked to four more states

The Iowa total stood at 184 cases as of July 23, compared with 61 by the same point last year, according to Iowa Public Radio reporting citing Iowa Health and Human Services. Iowa HHS has identified cases that may be related to the multistate outbreak, but more information is needed to confirm that connection.

What officials know about the outbreak

The CDC reported July 28 that it had received reports of 6,707 laboratory-confirmed, domestically acquired cyclosporiasis cases from May 1 through July 27. The cases were reported in 45 states. At that point, the agency reported 423 hospitalizations and no deaths in its domestic surveillance count.

That federal count is not a total of all illnesses in the United States. The CDC said it was aware of more than 11,500 additional cases that were not laboratory confirmed or still required investigation. CDC surveillance updates do not include probable cases, while state totals may include both probable and confirmed cases.

The CDC is investigating several clusters, including a nine-state outbreak linked to iceberg lettuce. On August 3, the agency said two people in Michigan with underlying health conditions had died as part of that outbreak. Those deaths were announced after the July 28 national surveillance update and are not reflected in the 6,707-case summary.

Taylor Farms recalled iceberg lettuce sourced from central Mexico on July 17. The FDA says affected products were distributed to Iowa and other states, but the recall applies to listed products and lots. It does not mean that all iceberg lettuce, or all fresh produce, is contaminated.

The CDC says its figures are preliminary and may increase because of reporting delays. The agency estimates a reporting lag of about six weeks between illness onset and case reporting.

How Iowa is investigating

Iowa HHS guidance requires health care providers and laboratories to report cyclosporiasis cases. Local public health agencies follow up with individual patients, and a broader investigation is warranted when case numbers are higher than usual or an outbreak is suspected.

Investigators use patient interviews, laboratory information and exposure histories to look for common food or water sources. Iowa HHS says the University of Iowa State Hygienic Laboratory provides stool testing for Cyclospora. State and local officials may also coordinate with food-safety agencies if a food or water source is suspected.

Iowa’s increase does not by itself establish that the state’s cases came from the recalled lettuce or are part of the nine-state outbreak. Public health officials use case interviews, laboratory results and food-traceback information to determine whether infections are connected.

Symptoms can last for weeks

Cyclosporiasis is caused by the microscopic parasite Cyclospora cayetanensis. Iowa HHS lists watery diarrhea as the typical symptom, along with nausea, vomiting, abdominal cramping, gas or bloating, fatigue, appetite loss, weight loss and low-grade fever.

Symptoms generally begin about one to two weeks after exposure, with an average of about one week. CDC guidance says illness can last from several days to a month or longer, and symptoms such as diarrhea may go away and return. Illness may last longer or be more serious for people who are immunocompromised.

The parasite is usually spread by consuming food or water contaminated with human feces. Iowa HHS says direct person-to-person transmission is not likely because the parasite must mature outside the body before it becomes infectious.

When to contact a health care provider

Persistent watery diarrhea or other prolonged gastrointestinal symptoms can have several causes. Testing may be needed to determine whether Cyclospora is involved. CDC says routine stool tests do not always screen for the parasite, so patients may need to ask a health care provider about Cyclospora-specific testing.

Medical advice is especially important for people with severe or prolonged illness, signs of dehydration, substantial weight loss or weakened immune systems. Residents should follow guidance from a health care provider rather than try to diagnose the illness from symptoms alone.

What residents should do now

Residents who bought recalled Taylor Farms products should check the recall notice, discard affected items or return them as directed, and clean surfaces that may have touched the recalled lettuce. The recall is product-specific; residents should not assume that all iceberg lettuce or fresh produce is unsafe.

CDC recommends washing hands and fresh produce under running water before eating, cutting or cooking. Washing cannot guarantee removal of Cyclospora, and cooking can kill the parasite.

For now, Iowa’s case increase and the national outbreak remain related questions, not a confirmed single event. Iowa HHS and federal and local partners are continuing interviews, laboratory review and outbreak investigations. Case totals and any confirmed source connections may change as delayed reports and additional testing are processed.

According to state officials, both people had underlying health conditions that may have been worsened by Cyclospora illness and dehydration. The deaths were reported after the Food and Drug Administration’s July 24 outbreak update, which listed zero deaths at that time. The different totals reflect different reporting dates, and the investigation remains ongoing. The deaths should not be interpreted as evidence that Cyclospora is commonly fatal.

Two different counts describe the problem

The FDA’s July 24 investigation focused on a nine-state outbreak involving people who reported Taco Bell exposure: Illinois, Indiana, Kansas, Kentucky, Michigan, Ohio, Oklahoma, Pennsylvania and West Virginia. At that point, the agency reported 1,947 confirmed illnesses and at least 98 hospitalizations, with no deaths reported in that update.

Investigators found that the illnesses converged epidemiologically and through traceback work on recalled shredded iceberg lettuce sourced from central Mexico by Taylor Farms de Mexico. The FDA said there were no confirmed positive product samples as of July 19. The lettuce connection was based on epidemiologic and traceback evidence, and the investigation continues.

The Centers for Disease Control and Prevention’s July 28 surveillance update covered a broader picture: 6,707 laboratory-confirmed domestically acquired cyclosporiasis cases, 423 hospitalizations and zero deaths reported nationwide from May 1 through July 27. Those figures cover domestic Cyclospora infections beyond the recalled-lettuce outbreak and included cases reported from 45 states.

The CDC also reported more than 11,500 additional cases that were not laboratory confirmed or still required investigation, with many reported by Michigan and Ohio. The figures are preliminary and may change. CDC estimates that reporting can lag illness by about six weeks, so the national total may continue to rise even after the recall.

What Cyclospora does

Cyclospora is a microscopic parasite that can cause cyclosporiasis, an intestinal illness. Common symptoms include watery diarrhea and frequent bowel movements, along with loss of appetite, weight loss, stomach cramps or pain, bloating, gas, nausea and fatigue. Vomiting, body aches, headache and fever can also occur, and some infected people have no symptoms.

Symptoms often begin about a week after exposure, but timing can vary. The illness may last for weeks or longer, and symptoms can improve and then return. Untreated illness can cause dehydration and complications that require medical care.

Seek medical attention for diarrhea lasting more than three days, diarrhea that returns after improving, or signs of dehydration such as very little urination, dizziness, unusual weakness, dry mouth or an inability to keep fluids down. Children, older adults, people with weakened immune systems and people with other conditions that make fluid loss more dangerous should contact a health care provider promptly if symptoms develop.

Tell the clinician about recent shredded-lettuce or restaurant exposure. Cyclospora may require a specific stool test, and health departments may need additional information or specimens to confirm and investigate a case.

What consumers should do with recalled lettuce

Consumers should check the FDA recall notice before eating or serving affected shredded iceberg lettuce. Recalled retail products included certain Walmart Marketside packages: 12- and 24-ounce Iceberg Salad products with best-if-used-by dates from July 18 through August 3, 2026, and 8- and 16-ounce Shredded Lettuce products with dates from July 18 through August 3, 2026. The recall also covered other products distributed to food-service customers.

The FDA identified confirmed product distribution across multiple states, and additional distribution may have occurred. Not all iceberg lettuce, all Taco Bell food or all restaurant locations are implicated. Check the specific recall information rather than relying only on the store, restaurant or brand name.

Do not try to wash or salvage recalled lettuce. Discard it, then clean and sanitize refrigerators, counters, containers and other surfaces it touched. Seek a refund where applicable. Taco Bell said it stopped using lettuce from Taylor Farms de Mexico as of July 17, 2026, but that statement does not mean every Taco Bell product or location was involved.

Why washing produce is not a guarantee

Cyclospora spreads when food or water is contaminated with human fecal matter. Direct person-to-person spread is considered unlikely because the parasite generally needs time outside the body before it becomes infectious.

Rinsing fresh produce under running water can reduce some contamination, but it is not a guarantee against Cyclospora. Do not wash produce with soap or bleach. For recalled food, disposal is the key safety step.

Testing and treatment

Doctors can treat cyclosporiasis with prescription medication, commonly trimethoprim-sulfamethoxazole. A clinician should determine whether testing and treatment are appropriate, especially for people who are dehydrated, have prolonged or relapsing diarrhea, or have conditions that increase the risk of complications.

The FDA, CDC and state health departments are continuing to investigate the outbreak. Official counts may change as delayed reports are reviewed, probable cases are separated from laboratory-confirmed cases and additional testing is completed.

The increase comes as federal officials investigate a nine-state Cyclospora outbreak linked to recalled iceberg lettuce sourced from central Mexico. The recalled product was distributed to Arkansas food-service customers and sold at select Walmart stores in the state. Officials have not established that all 123 Arkansas cases came from that lettuce.

Northwest Arkansas has the largest concentration

Benton County accounts for most of Arkansas’ confirmed cases. Washington County has the second-highest total, with 13 cases.

Fewer than 10 cases were reported in each of Boone, Carroll, Crawford, Faulkner, Marion, Miller, Pulaski, Saline, Sebastian and Van Buren counties. The distribution makes Northwest Arkansas the main concentration, but the reported cases extend across multiple Arkansas counties.

The Arkansas Department of Health said the state’s increase is partly associated with an ongoing multistate outbreak. Cyclosporiasis is an intestinal illness caused by the parasite Cyclospora cayetanensis and can result from contaminated food or water.

Arkansas cases are not the same as the federal outbreak count

The FDA and CDC say the federal investigation includes illnesses reported in Illinois, Indiana, Kansas, Kentucky, Michigan, Ohio, Oklahoma, Pennsylvania and West Virginia. Arkansas is listed as a state where recalled product was distributed, not as one of the nine states in the federal case count.

As of the federal update dated July 24, the CDC reported at least 1,947 illnesses and 98 hospitalizations among people in those nine states who reported Taco Bell exposure. No deaths had been reported. Federal officials said those illnesses are only a subset of Cyclospora infections identified nationwide and that other illnesses may be unrelated to the lettuce investigation.

State and federal totals may not match because of reporting timelines and case classifications. The FDA says state data may include probable and confirmed cases or initial reports not yet sent to the CDC, while federal totals use a narrower case count. National surveillance numbers also include illnesses outside this particular investigation.

The FDA investigation remains open. Federal officials say epidemiological and traceback evidence points to shredded iceberg lettuce supplied by Taylor Farms de Mexico, but the FDA reported no confirmed positive product sample as of July 19. The recall is therefore based on the broader investigation and evidence connecting the product to illnesses, not on a confirmed positive test from every recalled item or every patient.

What Arkansas residents should do

Residents should check whether they purchased or received recalled iceberg lettuce from Taylor Farms de Mexico. The recall includes Marketside products sold at select Walmart stores, as well as products distributed to food-service customers.

Do not eat recalled products. Throw them away or return them to the place of purchase for a refund. Clean and sanitize containers, cutting boards, refrigerator areas and other surfaces that may have touched the lettuce. The CDC recommends washing items and surfaces with hot, soapy water or using a dishwasher when appropriate.

The FDA lists Marketside iceberg salad packages of 12 or 24 ounces with “Best if Used By” dates from July 18 through Aug. 3, 2026, and shredded lettuce packages of 8 or 16 ounces with dates from July 18 through Aug. 3, 2026. Residents should use the complete recall notice to check package details, lot information and other affected food-service products.

Symptoms and testing

Common symptoms include watery or frequent diarrhea, fatigue, loss of appetite, weight loss, stomach cramps, bloating, increased gas and nausea. Symptoms usually begin about one week after infection but can appear as soon as two days or more than two weeks later. Without treatment, symptoms can last from a few days to a month or longer and may return after improving.

People with persistent or frequent watery diarrhea should contact a health care provider and ask whether Cyclospora testing is appropriate, particularly if they ate recalled shredded iceberg lettuce before becoming sick. Routine stool tests do not always screen for the parasite. Staying well-hydrated is important because prolonged diarrhea can cause dehydration.

Residents should wash fresh produce under running water, but washing alone cannot guarantee removal of Cyclospora. Soap, bleach and household cleaners should not be used on food.

What remains unresolved

Arkansas officials have not linked every confirmed case to the recalled lettuce, and lettuce has not been established as the only possible source of infection in the state. The FDA also says additional implicated brands, restaurants, retailers or distribution channels could be identified as the investigation continues.

Because public health officials are still reviewing reports and exposures, Arkansas case totals and federal product guidance may change. Residents with symptoms should contact a health care provider and follow updates from the Arkansas Department of Health, FDA and CDC.

As of the FDA‘s July 24, 2026 update, 1,947 people in nine states had reported Cyclospora illness after Taco Bell exposure. At least 98 people had been hospitalized, and no deaths had been reported. Illness-onset dates ranged from June 22 through July 20, 2026.

The investigation remains ongoing. Federal officials expect the case count to rise because it can take as long as six weeks to determine whether an illness belongs to the outbreak.

What investigators found

The FDA said epidemiological information and traceback evidence continued to converge on shredded iceberg lettuce supplied by Taylor Farms de Mexico and served at Taco Bell restaurants where sick people had eaten. The finding does not mean every Taco Bell location or every Taco Bell food item was unsafe.

The FDA also said that, as of July 19, no product sample had been confirmed positive for Cyclospora. A false-positive border sample did not change the basis for the agency’s ongoing investigation or the voluntary recall supported by the epidemiological and traceback evidence.

The nine states with Taco Bell-exposure cases are Illinois, Indiana, Kansas, Kentucky, Michigan, Ohio, Oklahoma, Pennsylvania and West Virginia. State totals may differ because states can include probable cases or reports that have not yet been incorporated into the federal count.

What the recall covers

On July 17, Taylor Farms de Mexico announced that it was voluntarily removing iceberg lettuce sourced from central Mexico from the U.S. market. The FDA recall record identifies Taylor Fresh Foods as the company associated with the recall.

Taylor Fresh Foods distributed recalled iceberg lettuce products to food-service customers from June 29 through July 16 in 28 states: Alabama, Arkansas, Connecticut, Florida, Georgia, Iowa, Illinois, Indiana, Kansas, Kentucky, Louisiana, Massachusetts, Maryland, Michigan, Missouri, Mississippi, North Carolina, New Hampshire, New Jersey, Ohio, Oklahoma, Pennsylvania, South Carolina, Tennessee, Texas, Virginia, Wisconsin and West Virginia.

The recalled products include food-service items such as shredded lettuce, chopped lettuce, salad mixes, lettuce blends and prepared salad products. Some listed use-by dates extend through Aug. 3, 2026. The 28-state distribution list shows where distribution was confirmed; it does not mean every restaurant or retailer in those states received the lettuce.

The recall also includes certain Marketside iceberg salad and shredded-lettuce products sold at select Walmart stores. Consumers should check the FDA recall notice for product descriptions, lot information and dates rather than assuming that every Taylor Farms product or all lettuce nationwide is affected.

What Taco Bell and other chains are doing

Taco Bell said it stopped using lettuce from Taylor Farms de Mexico as of July 17. That was a precautionary supply action as the investigation developed, not a finding that all food served by the chain was contaminated.

The outbreak has also affected restaurant traffic beyond the locations named in the federal investigation. The Associated Press reported that Yum Brands said Taco Bell’s U.S. same-store sales were down 2% so far in the July-September period, compared with a 7% increase in the previous quarter. AP also reported that Chipotle lowered its same-store-sales outlook because of weaker traffic linked to consumer concern.

AP cited market-research data showing a decline in foot traffic at Chopt and lower year-over-year spending at Sweetgreen. Neither chain was identified by federal officials as an outbreak source, and Sweetgreen said its food had not been connected to the outbreak.

Symptoms and what to do

Cyclospora commonly causes watery or frequent diarrhea. Other symptoms can include loss of appetite, weight loss, stomach cramps or pain, bloating, increased gas, nausea and fatigue. Vomiting, body aches, headache and fever may also occur. Symptoms can improve and return, and untreated illness can lead to dehydration or more serious complications.

Diners who ate shredded iceberg lettuce at Taco Bell during the affected period and develop persistent or recurring diarrhea should contact a health care provider and report the possible exposure. The CDC identifies prescription treatment as the standard treatment approach, but diagnosis and treatment decisions should be handled by a medical professional.

Restaurants and retailers should check receiving records and lot information against the Taylor Fresh Foods recall, remove recalled products from service or sale, discard them according to the recall instructions and clean and sanitize food-contact surfaces and containers the lettuce touched. Consumers should not eat recalled lettuce and should clean and sanitize surfaces or containers it contacted. Refunds are available at the location of purchase for recalled products.

The FDA says additional restaurants, retailers, distribution channels or states could be identified as the investigation continues.

No cases linked to the outbreak had been identified in Los Angeles County at the time of the county notice. The alert does not describe a Los Angeles County outbreak; it reports the county’s surveillance status during a broader investigation.

Nationally, the Centers for Disease Control and Prevention had received reports of 1,645 laboratory-confirmed U.S. cases as of July 13, according to the county. That is compared with 249 cases reported nationally by the comparable point in 2025.

What is known — and what remains under investigation

The Los Angeles County Department of Public Health characterized the event as a multijurisdictional outbreak that was domestically acquired. State and federal public-health agencies were investigating it.

The available county notice did not identify a confirmed food source, restaurant or supplier. It also did not establish that the higher national count resulted from one common exposure. Those distinctions matter because an investigation can involve case reports across jurisdictions before investigators determine whether, and how, cases are connected.

The 1,645 figure is a national count of laboratory-confirmed reports received by the CDC, not a count of Los Angeles County cases. The county’s reported local figure was zero linked cases as of its July 13 alert.

Guidance for county residents

County Public Health included information intended to help residents reduce infection risk and recognize symptoms. The notice is public-health guidance, rather than a county mandate or a finding that people in Los Angeles County have been exposed through a particular food or business.

Residents seeking information should rely on updates from the Los Angeles County Department of Public Health and other public-health agencies as the investigation develops. The agency’s monitoring notice provides the county-specific context: a national outbreak was being investigated, while no linked cases had been identified locally at the time of publication.

Case totals and local status can change after an initial alert. The county’s reported figures and its no-linked-cases status are dated to July 13, 2026, and should be read as a snapshot from that reporting date rather than a final account of the investigation.

Why the alert matters

The notice gives Los Angeles County residents a current update on a foodborne-disease investigation while separating the nationwide case count from local conditions. It also signals that county health officials are tracking the investigation and sharing prevention and symptom information even though no outbreak-linked county cases had been identified.

The practical answer is limited: local sourcing or a hydroponic growing method does not guarantee safety. Risk depends on factors including water quality, harvesting, worker sanitation, storage and handling. The City of Overland Park identifies the market as a place where shoppers can buy local in-season produce, but no market vendor or product has been identified in the sources reviewed as contaminated.

What officials are investigating

In a July 24 alert, the Centers for Disease Control and Prevention said it was investigating an open, multistate outbreak of Cyclospora infections linked to iceberg lettuce in nine states. At that time, the CDC reported at least 1,947 cases, 98 hospitalizations and no deaths. The agency also said it was investigating other Cyclospora illnesses nationally that may be unrelated to this outbreak.

On July 17, Taylor Farms de Mexico recalled all iceberg lettuce sourced from central Mexico. The retail products identified by Kansas health officials were Marketside 12-ounce and 24-ounce Iceberg Salad packages and Marketside 8-ounce and 16-ounce Shredded Lettuce packages sold at Walmart, with best-if-used-by dates from July 18 through Aug. 3, 2026. Other recalled lettuce was distributed to restaurants and food-service facilities.

Kansas health officials said July 22 that the state had recorded 289 total cyclosporiasis cases in 2026. Of those, 114 were classified as domestically acquired, 24 were likely linked to international travel, six could not yet be classified and 145 were pending classification. KDHE updates its case information each Wednesday, so the July 22 figure is a dated snapshot, not an Aug. 1 total.

What the recall means for Overland Park shoppers

The recall applies to specified iceberg lettuce from Taylor Farms de Mexico, not every Taylor Farms product and not all lettuce. Check package names, best-if-used-by dates and lot information against the current recall notice before eating or serving packaged lettuce.

Do not eat recalled lettuce. Throw it away or return it. Wash items and surfaces that may have touched the lettuce with hot, soapy water or in a dishwasher.

Is farmers-market or hydroponic produce safer?

Recent reporting by KCUR and the Kansas News Service found that Cyclospora concerns were affecting shoppers and vendors at the Overland Park Farmers’ Market. The report described questions about hydroponically grown lettuce and herbs, imported produce and products that may have passed through large-scale processing or distribution systems.

Food-safety experts cautioned against treating local origin, farm size or hydroponic production as a guarantee. Cyclospora spreads through food or water contaminated with human waste, and safety depends on the practices used at each stage. Shoppers can ask farmers-market vendors about irrigation water, harvesting, cooling, sanitation and product tracking.

Local produce may offer potential traceability or handling advantages in some situations, but those factors do not prove that food is uncontaminated. Consumers should not stop eating fresh produce altogether.

Steps to reduce risk

• Check recall notices before eating or serving packaged lettuce.
• Wash hands and fresh produce thoroughly under running water before eating, cutting or cooking, even when produce is labeled “pre-washed.”
• Scrub firm produce, such as melons and cucumbers, with a clean produce brush, and cut away damaged or bruised areas.
• Refrigerate cut, peeled or cooked produce as soon as possible, within two hours.
• Understand that washing cannot guarantee removal of Cyclospora.
• Cook produce when possible. The CDC and KDHE say heating it to at least 158 degrees Fahrenheit can kill or inactivate the parasite.

Symptoms and when to seek care

Symptoms can begin about one week after exposure, with a range from two days to two weeks or more. They may include watery diarrhea, fatigue, loss of appetite, weight loss, abdominal cramps, bloating, increased gas and nausea. Vomiting and a low-grade fever are less common.

Untreated illness can last from a few days to a month or longer. Persistent or severe gastrointestinal symptoms, especially signs of dehydration, warrant medical evaluation. Tell a health care provider about possible Cyclospora exposure because routine stool tests may not screen for the parasite and specific testing may be needed. Stay hydrated and do not attempt to diagnose yourself.

The investigation remains open. For Overland Park shoppers, the useful response is to check recalls, ask reasonable food-safety questions, handle produce carefully and follow Wednesday updates from KDHE along with CDC outbreak guidance.

At least 98 people have been hospitalized, and the FDA reported no deaths. The continuing recall and investigation are testing how quickly the U.S. food-safety system can detect an outbreak, trace an ingredient through restaurants and retailers, and communicate what consumers should do when laboratory evidence is incomplete.

What federal investigators have confirmed

The outbreak includes reported illnesses in Illinois, Indiana, Kansas, Kentucky, Michigan, Ohio, Oklahoma, Pennsylvania and West Virginia. Illness-onset dates listed in the FDA update range from June 22 through July 20, 2026.

The FDA said additional cases may be added because it can take up to six weeks for federal and state officials to determine whether a sick person belongs to the outbreak. The agency also cautioned that this outbreak is only a subset of Cyclospora infections identified nationwide, so not every Cyclospora case reported in the United States is part of this investigation.

FDA and CDC investigators say traceback work, epidemiological evidence and exposure information continue to converge on shredded iceberg lettuce supplied by Taylor Farms de Mexico and sourced from central Mexico. That identifies the direction of the investigation, but it does not establish a final legal or laboratory finding that Taylor Farms was conclusively the source of contamination.

What was recalled and where it went

Taylor Farms de Mexico announced on July 17 that it was voluntarily removing iceberg lettuce sourced from central Mexico from the U.S. market. The recall included food-service lettuce distributed to customers in 27 states, as well as select Marketside iceberg salad and shredded lettuce products sold at Walmart stores in 15 states.

The distribution footprint is broader than the nine states listed in the federal outbreak count. Consumers and businesses therefore should not assume that a location outside those states is unaffected. The FDA recall notice lists affected product descriptions, date codes and distribution information.

Why the false-positive result matters

A lettuce sample was reported as positive on July 18, but the FDA said on July 19 that laboratory experts had re-reviewed the result and classified it as a false positive. As of the July 24 update, the agency said it had no confirmed positive product-test results for Cyclospora.

That means investigators do not have a simple laboratory result proving that recalled lettuce contained the parasite. It did not, however, change the FDA’s stated basis for continuing the recall and investigation. The agency said traceback findings and epidemiological data still converge on shredded iceberg lettuce from Taylor Farms growers in central Mexico.

The distinction matters for public accountability. Investigators must act quickly to reduce exposure while explaining what is known, what is inferred and what remains unproven. The Associated Press reported that confirming Cyclospora in food samples can be difficult because testing is limited and the parasite cannot be grown in laboratories. Investigators therefore rely heavily on what people ate, the timing of illnesses and supply-chain patterns.

Axios has used the outbreak to examine broader questions about surveillance, ingredient-level traceback and public communication. That reporting provides context for the national food-safety challenge, not an official finding that the system failed or that contamination has been conclusively located.

What consumers and businesses should do

Consumers should check refrigerators and freezers against the FDA recall list. Do not taste, wash or serve a recalled product. Discard it, ask the place of purchase about a refund, and carefully clean and sanitize surfaces or containers that the lettuce touched.

Restaurants, retailers and other businesses should check food-service inventories, receiving records and prepared foods that may contain recalled lettuce. The recall list is broader than the nine states currently reporting outbreak cases.

Cyclospora commonly causes persistent or recurring diarrhea. Other symptoms can include loss of appetite, weight loss, stomach pain, bloating, nausea, fatigue and dehydration. People with possible symptoms should contact a health-care provider, especially if they recently ate shredded iceberg lettuce or ate at a Taco Bell location associated with the investigation.

What to watch next

The next important developments will be updated federal case counts, additional traceback findings, laboratory results and any new product, restaurant or distribution notices. Because the investigation remains ongoing, officials may identify additional cases, products, states or distribution channels.

For now, the central question remains open. Federal evidence continues to point toward a lettuce supply chain, but the July 24 update did not provide a confirmed positive product test or a final explanation of how Cyclospora entered the food system.

• Associated Press reporting

For Ohio residents, the immediate public-health advice is to avoid recalled Taylor Farms de Mexico iceberg lettuce, discard affected products, clean and sanitize surfaces or containers they touched, and contact a health care provider about persistent or recurring symptoms.

FDA investigation now covers nine states

In a July 24 update, the Food and Drug Administration said the investigation includes Illinois, Indiana, Kansas, Kentucky, Michigan, Ohio, Oklahoma, Pennsylvania and West Virginia.

Federal officials reported 1,947 confirmed illnesses, at least 98 hospitalizations and no deaths as of July 24. Illnesses began between June 22 and July 20, although officials expect the confirmed count to continue rising because it can take as long as six weeks to determine whether a sick person is part of the outbreak.

The illnesses under investigation include people who reported eating at Taco Bell. FDA traceback work and epidemiological information have converged on shredded iceberg lettuce supplied by Taylor Farms de Mexico from growers in central Mexico.

That evidence prompted a voluntary recall, but FDA said the investigation remains ongoing. As of July 24, no product sample had conclusively tested positive for Cyclospora. A previously reported positive sample collected at the border was later determined to be a false positive, according to FDA.

Why Ohio’s number is higher than the federal total

Spectrum News reported more than 2,600 cyclosporiasis cases in Ohio on July 24, roughly twice the number reported the previous week. That figure should not be added to or compared directly with FDA’s 1,947 confirmed outbreak illnesses.

FDA says state data may include probable and confirmed cases, along with initial reports that have not yet been sent to federal officials. The FDA and CDC outbreak figure counts confirmed illnesses reported by the nine states among people who reported Taco Bell exposure. The totals also reflect different definitions and reporting timelines.

The Ohio Department of Health requested CDC assistance with patient interviews and data management. Investigators will compare what patients ate and where they went with laboratory and food-traceback evidence before confirming the source of the outbreak.

Recalled lettuce reached Ohio food-service customers

The FDA-posted Taylor Fresh Foods recall says recalled shredded iceberg lettuce was distributed to food-service customers in Ohio from June 29 through July 16, 2026. The recall covers multiple food-service products and date ranges, including shredded, chopped and salad-mix lettuce sold under several brand or customer codes.

Consumers, restaurants and retailers that purchased or received recalled Taylor Farms iceberg lettuce should not eat it. They should discard it, clean and sanitize surfaces or containers the product touched, and seek a refund from the place of purchase. The recall notice contains the affected product descriptions, lot information and use-by dates.

FDA’s listed retail-store states for recalled Marketside products do not include Ohio. Ohio residents should not assume those Walmart retail products were sold in the state based only on the broader recall. They should check the specific product, distribution channel, date and lot information in the recall notice.

Residents should not rely on smell or appearance to decide whether recalled lettuce is safe. Recalled food should be discarded according to the instructions even if it looks or smells normal.

Symptoms and when to seek care

Cyclospora commonly causes persistent or frequent diarrhea. Other symptoms can include loss of appetite, weight loss, stomach cramps or pain, bloating, increased gas, nausea and fatigue. Vomiting, body aches, headache and fever may also occur, and some infected people have no symptoms.

Untreated illness can cause dehydration and severe complications. Those complications may last from several days to a month or longer, and symptoms can appear to improve before returning in one or more relapses. People with prolonged or recurring diarrhea, signs of dehydration or related symptoms should contact a health care provider, particularly if they ate shredded iceberg lettuce in the two weeks before becoming sick.

What happens next

CDC investigators are expected to assist Ohio with interviews and data management while federal, state and local officials continue case review, traceback work and product testing.

Officials may identify additional cases, restaurants, retailers or distribution channels as the investigation continues. Current evidence points investigators toward recalled shredded iceberg lettuce, but it has not established that every Taco Bell location or every iceberg lettuce product is affected.

Sources

• FDA outbreak investigation update
• Spectrum News Ohio CDC investigation report
• Associated Press outbreak report

The investigation remains active. Federal officials said the case count may continue to rise because it can take up to six weeks for health authorities to determine whether a reported illness is part of the outbreak.

What changed on July 24

Illinois, Kansas, Oklahoma and Pennsylvania were added to five states previously identified: Indiana, Kentucky, Michigan, Ohio and West Virginia.

The FDA said the investigation involves people who reported exposure to Taco Bell. That does not mean every Taco Bell customer was exposed or infected, and the reported exposure alone does not establish that every illness was caused by recalled lettuce.

Which lettuce products are involved

Federal officials are investigating shredded iceberg lettuce sourced from central Mexico and associated with Taylor Fresh Foods. Recalled products moved through food-service channels in 28 states and included shredded, chopped and blended lettuce products.

Select Walmart stores also sold recalled Marketside-brand products, including iceberg salad and shredded lettuce. The FDA recall notice lists the affected product descriptions and best-if-used-by dates.

The recall does not apply to all lettuce sold at Walmart, all Taco Bell food or every product served at every restaurant. Consumers should compare packages, product descriptions and dates with the current FDA recall notice before deciding whether an item is affected.

What consumers should do

Do not eat, serve or sell recalled lettuce. The FDA says consumers, restaurants and retailers should discard affected products or follow the recall instructions for a refund. Surfaces and containers that came into contact with recalled lettuce should be cleaned and sanitized according to the agency’s guidance.

Consumers should check refrigerators, freezers and food-service receipts for recalled Taylor Fresh Foods lettuce or affected Marketside products. The FDA outbreak advisory and recall notice provide the current product details.

Symptoms and timing

Cyclospora commonly causes frequent, watery diarrhea. Other possible symptoms include loss of appetite, weight loss, stomach cramps or pain, bloating, increased gas, nausea and fatigue. Vomiting, body aches, headache and fever can also occur, while some infected people may have no symptoms.

People with possible symptoms or concerns about a recent exposure should contact a health professional. The FDA notes that illness can last for weeks and may return after seeming to improve. Symptoms may not appear immediately after exposure, which is one reason recent food history can matter when speaking with a clinician.

What remains unknown

Officials have not established that every illness involving reported Taco Bell exposure came from recalled lettuce, and the investigation has not shown that every iceberg lettuce product or distribution channel is affected.

The FDA’s traceback work and outbreak data continue to point toward recalled shredded iceberg lettuce associated with Taylor Fresh Foods, but the investigation and case review remain underway. Reported totals may change as officials classify additional illnesses.

Consumers should rely on the current FDA outbreak advisory, recall notice and Cyclospora health guidance rather than assuming that a restaurant, retailer or package is affected solely because it sold or served lettuce.

Here’s what changed, what product channels FDA is basing current guidance on, and the practical steps FDA says consumers should take now.

What changed in FDA’s investigation

On July 19, 2026, FDA posted new context on its investigation of a 5-State cyclospora outbreak linked to iceberg lettuce. FDA clarified that an earlier lab finding was later determined to be a false positive, meaning it should not be treated as confirmed evidence connecting the illness investigation to product testing results.

FDA also emphasized that the investigation is still ongoing. Federal and state partners continue working with FDA’s sampling and testing to better define the evidence and the scope of any implicated product.

What FDA says is implicated (and why guidance is not “everywhere”)

FDA’s consumer guidance is tied to the specific supply chain and distribution channels described in its investigation materials and recall/market-withdrawal pages—not a blanket claim that all iceberg lettuce nationwide is affected.

In the materials FDA provided for this investigation, the focus is on iceberg lettuce connected to the supplier channel described in FDA’s posted recall guidance (including the Taylor Fresh Foods/Taylor Farms de Mexico channel referenced in FDA materials). FDA also tied its consumer/food-service messaging to a five-state framework and to food-service exposure scenarios described in the investigation.

What to do now (FDA’s practical consumer steps)

• Check whether you still have implicated iceberg lettuce. If you have the kind of recalled/implicated iceberg lettuce referenced by FDA’s guidance and recall listing, do not eat it and follow FDA’s instructions for that recall.
• Follow FDA’s discard/avoid instructions. FDA’s posted recall guidance is the controlling step for what to throw out and how to proceed if you purchased the implicated product through the channels FDA identified.
• If you ate from food service and you feel sick, contact a clinician. If you develop symptoms consistent with Cyclospora illness (cyclosporiasis), seek medical care and mention any relevant food exposure tied to FDA’s investigation guidance.
• Do not assume the “false positive” means “risk is zero.” FDA says testing is continuing, and its materials distinguish between what has been confirmed and what remains under investigation.

What to watch next

FDA updates its investigation page and may adjust consumer guidance as sampling and testing results come in. The key watch-items for readers are: (1) further clarifications on what evidence is confirmed versus still being tested, and (2) any updates to recall/market-withdrawal instructions that change what consumers should discard or avoid.

Below is what changed in this latest FDA/CDC update, who’s affected based on investigators’ case interviews, and what to do next.

Quick facts from the July 16 FDA/CDC update

• States included: IN, KY, MI, OH, WV
• Reported exposure/infections: 1,644 people who reported eating at Taco Bell
• Hospitalizations: 94
• Deaths reported: none
• Implicated food: shredded iceberg lettuce from Mexico served at Taco Bell

Important nuance: FDA says not all Taco Bell locations in those states received the implicated product.

What’s new in the update: traceback narrowed to one Mexico supplier

FDA says its traceback work has converged on a single supplier of iceberg lettuce from Mexico used by the Taco Bell locations where sick people ate before they got ill.

FDA also reports it is working directly with that supplier and that state partners have begun collecting product samples for testing and analysis. The agency adds that it has increased border screening for products implicated in the outbreak. FDA says Taco Bell has committed to stop using lettuce from the identified supplier.

CDC lists the outbreak as open and says no recall has been issued in its current advisory.

What’s known vs. still under investigation

• Known: The cases in this advisory are a subset of Cyclospora illnesses nationwide and are linked to shredded iceberg lettuce served at Taco Bell in the five listed states.
• Still being investigated: FDA says additional implicated brands, restaurants, retailers, or distribution channels may be identified as testing and traceback continue.
• Counts can shift: FDA notes case counts may differ from how individual states report probable vs. confirmed cases, and numbers can update as confirmed cases are added.

Symptoms to watch for (and when to seek care)

CDC says primary cyclosporiasis symptoms can include watery diarrhea, fatigue, and loss of appetite. Symptoms usually begin about one week after infection, but CDC says timing can range from 2 days to 2 weeks or more.

CDC also warns that people who are sick may need to specifically request Cyclospora testing, because routine stool tests don’t always screen for the parasite. If symptoms develop, CDC recommends staying well hydrated and contacting a healthcare provider—especially if you ate the implicated lettuce in the two weeks before you got sick.

If you ate or handled the implicated lettuce: practical next steps

FDA advises consumers who purchased or received food items with shredded iceberg lettuce served at Taco Bell at these locations to carefully clean and sanitize any surfaces or containers the food touched, following FDA safe-handling and cleaning guidance.

What to watch next

With traceback narrowed to one supplier, the next updates that matter most for consumers are whether investigators confirm the contaminated product’s distribution beyond the currently named states, and how case counts change as interviews and testing continue.
