The New World screwworm fly is a parasitic fly whose larvae feed on animals, particularly livestock, wildlife, and pets, causing serious injury or death if untreated; however, it is not a food safety issue or an infectious disease that spreads like a virus. Prevention and control involve releasing sterile flies to break the reproduction cycle, with Texas implementing a statewide disaster declaration, deploying sterile fly production facilities, and establishing surveillance zones. The condition is highly treatable with proper veterinary intervention, and early detection through public reporting is critical for effective response.
