FDA update (July 16): Cyclospora outbreak linked to Taco Bell shredded lettuce

FDA and CDC updated their Cyclospora outbreak alert on July 16, 2026, saying people should not eat shredded iceberg lettuce from Mexico served at Taco Bell locations in Indiana, Kentucky, Michigan, Ohio, and West Virginia. The agencies say the investigation is ongoing and could expand as testing and traceback continue.

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.
