FDA’s Center for Veterinary Medicine is writing to follow up USDA’s announcement that New World screwworm (NWS), Cochliomyia hominivorax, has been detected in Texas near the U.S.-Mexico border.

This letter is intended to share resources to help you identify FDA-authorized or conditionally approved drugs for NWS myiasis and to explain veterinarians’ responsibilities when prescribing drugs with Emergency Use Authorizations (EUAs) for the prevention and/or treatment of NWS myiasis. FDA has been diligently working to prepare for NWS, including by issuing EUAs for animal drugs for the first time. We appreciate this is uncharted territory for you, and CVM stands ready to help veterinarians.

FDA issued a Dear Veterinarian Letter about FDA-authorized drugs for New World screwworm + vet responsibilities when prescribing these drugs.

On June 5th, a sample collected from a 30-day-old calf in Zavala County was confirmed to be New World screwworm (NWS). This is the second confirmed case of NWS in Texas, and is located within the existing infested zone. Animal health officials are actively working the case and continuing to expand fly trapping and surveillance efforts to identify additional flies in the area.

Animal owners and livestock producers in Texas should actively monitor their animals and quickly treat and cover any wounds. This area is currently under movement restrictions through the Executive Director Order issued on June 3rd.

JUNE 03, 2026 – The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) confirmed the detection of a New World screwworm (NWS) in a bovine in Zavala County, Texas. NWS is a serious pest that affects livestock, pets, wildlife, and less commonly, people and birds. NWS larvae (maggots) burrow into the flesh of living animals, causing serious damage to livestock and economic losses.

The affected animal is a 3-week-old calf and larvae were identified in its umbilical area. To date, there have been no further detections.
