For Carrizo Springs readers, that makes this a practical ranch and pet-owner issue. Nearby South Texas livestock movement can be slowed by inspection rules, treatment checks, and the need to keep paperwork current before animals travel to auctions, vets, or other properties.

What to watch for

Officials say to look for draining or enlarging wounds, foul odors, swelling, maggots, or eggs, especially around the nose, ears, navel, or genital area. Keep open wounds clean and covered, and report suspected Texas livestock cases within 24 hours.

Texas livestock reports go to the TAHC region office or the state veterinarian on call at 1-800-550-8242. USDA says the broader response still centers on surveillance, movement controls, and sterile fly releases, and NRCS Texas says it can offer technical assistance to producers.

Officials say the case was detected June 7, 2026, and confirmed June 9, 2026 in a dog. In response, state officials established a 12-mile infested zone and expanded monitoring to catch any signs of spread early.

What officials say is confirmed—and what the “infested zone” means

NMDA reports a 12-mile infested zone around the affected animal’s location to support surveillance, treatment, and safe animal movement. Within that zone, animals must be inspected and, if necessary, treated before moving within or out of the area.

State and federal officials also describe a broader surveillance zone extending beyond the infested zone, with increased surveillance and fly trapping to look for evidence the pest may be spreading.

Officials say routine animal movement—like traveling to livestock auctions, fairs, veterinary visits, or recreational trips—is generally not restricted unless an inspector flags a higher-risk situation based on animal health or wound status.

What to do today: check wounds fast and report quickly

NMDA lists warning signs that may include:

• Wounds that fail to heal or worsen over time
• Maggots in a wound
• Foul-smelling or draining wounds
• Animals persistently licking, biting, or aggravating a wound
• Irritation, discomfort, or unusual behavior around an injury site

For Lovington-area owners, the practical steps start with this: inspect any wound that isn’t healing normally. If you see a suspicious wound—or suspect New World screwworm—immediately contact the New Mexico Livestock Board and avoid moving the affected animal.

NMDA also advises owners to keep open wounds clean and covered. Animals infested with New World screwworm should be treated right away under a veterinarian’s direction.

NMSU notes the same core approach—regular inspections, watching for warning signs, and acting quickly. It also encourages residents to consult a veterinarian for diagnosis and treatment options and to report suspected cases to the Livestock Board by calling 505-841-6161 or using the reporting resources linked by NMSU.

Local help: free screwworm testing kits via county Extension

New Mexico’s response includes a free New World screwworm testing program. NMSU reports that testing kits are available at all 33 county Extension offices, and that samples should be submitted only if screwworm is strongly suspected.

Where to follow updates next

For ongoing federal tracking and the latest confirmed-detection information, USDA APHIS maintains a New World screwworm “current status” page. It also includes steps for reporting suspected cases and links to related response and regional trade-restriction information.

This isn’t a reason to panic. It is a reason to tighten routines: check wounds quickly and report suspected cases without delay—especially for pets, livestock, and wildlife with injuries that don’t look right.
