USDA Confirms New World Screwworm Detection in Texas, Prompting Agricultural Response
The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) has confirmed the detection of a New World screwworm (NWS) in a bovine in Zavala County, Texas. This pest, which affects livestock, pets, wildlife, and occasionally humans, was found in a 3-week-old calf. The larvae of the screwworm burrow into the flesh of living animals, causing significant damage and economic losses. This marks the first detection of NWS in the United States in decades, prompting immediate responses from agricultural groups. R-CALF USA and the National Cattlemen’s Beef Association (NCBA) have both issued statements emphasizing the need for a coordinated response to protect livestock and the national food supply. Measures are being taken to eradicate the pest, including building a domestic sterile fly facility and increasing fly surveillance.
