The Exotic Wildlife Association’s New World Screwworm (NWS) Resource Guide was developed to provide producers, ranchers, and animal owners with a centralized reference for the latest information on NWS. The guide includes an overview of the parasite and its life cycle, signs of infestation, species at risk, reporting procedures, treatment and prevention considerations, movement restrictions, regulatory updates, and links to additional state and federal resources. It is designed to help producers better understand the threat posed by NWS and support preparedness and response efforts across the industry.
Early detection and rapid response remain critical to preventing the spread of NWS. Producers are strongly encouraged to establish and maintain a valid Veterinarian-Client-Patient Relationship (VCPR) before an issue arises, as timely access to veterinary guidance can be essential when suspicious wounds or infestations are observed. If NWS is suspected, contact your veterinarian immediately and follow all applicable reporting requirements. Regular animal inspections, prompt treatment of wounds, and ongoing communication with your veterinarian are among the most important steps producers can take to protect animal health and support statewide response efforts.
