What started as a single detection of New World screwworm in Zavala County on June 3rd has expanded to multiple confirmed cases across Zavala, La Salle, and Gillespie Counties in Texas, as well as Lea County, New Mexico. Cases have been found in cattle, and notably, a dog in Andrews County, Texas — a reminder that this pest affects all warm-blooded animals, not just livestock. USDA has activated a sterile fly release facility at Moore Air Base in Edinburg, Texas, with aerial drops now underway in affected areas of Texas and northern Mexico near the border.
At TFP Nutrition, we're committed to staying on top of this situation and keeping our dealers and customers informed as it develops. If you work with cattle or other livestock in South Texas or border regions, inspect your animals daily for draining wounds or unusual signs of discomfort — and contact your veterinarian or state animal health official immediately if something looks off. Early detection is one of the most effective tools available. We've faced this threat before and eradicated it, and with the right response, we can do it again. We're here to support the operations and communities that depend on us. For the latest confirmed detections, visit screwworm.gov.
