USDA Steps Up Screwworm Defense Efforts

USDA’s Animal and Plant Health Inspection Service is expanding its New World screwworm prevention efforts into Texas. Beginning January 30, sterile fly dispersal operations have moved about 50 miles into south Texas along the border with Tamaulipas, Mexico, to stop the pest’s northward spread. Officials say no screwworm has been detected in Texas, and the sterile flies pose no risk to people or livestock. The program is a preventive step designed to reduce egg production and protect U.S. herds from potential infestations.
