Tonight, USDA confirmed the detection of a New World Screwworm (NWS) fly in a 3 week old bovine in Zavala County, Texas.
Livestock markets and dealers remain committed to maintaining an orderly and efficient marketplace while implementing any necessary animal health requirements. Livestock marketers across the country have been preparing for NWS for over a year through training, planning, and coordination with USDA, state animal health officials, and other industry organizations.
Livestock markets and dealers serve as a critical point for animal health surveillance and communication. Marketers are committed to helping identify potential cases, sharing accurate information with producers, and supporting response efforts in affected areas.
Facts, science-based decision making, and cooperation across the industry will be essential to successfully controlling and ultimately eliminating NWS and up-to-date information can be found at www.screwworm.gov.
