USDA allocates $105 M to fight New World screwworm outbreak

The U.S. Department of Agriculture has granted $105 million to 40 research projects under its New World Screwworm Grand Challenge, aiming to improve detection, control and eradication of the invasive parasite. Texas A&M AgriLife will lead seven proposals and contribute to seven others, focusing on sterile‑fly production, novel traps, therapeutics and preparedness tools.

The USDA is also partnering with the Department of Homeland Security to deploy AI‑controlled drones and other innovative methods, while the American Veterinary Medical Association has set up a centralized hub of clinical resources to help veterinarians diagnose and treat infected animals. Twelve animal cases—cattle, sheep, goats and a dog—have been confirmed in Texas and New Mexico, with active monitoring by state and federal officials.

Ranchers and auction barns in Texas are tightening biosecurity, using ivermectin treatments and adhering to quarantine protocols, while the Texas Animal Health Commission coordinates the response with USDA and Texas A&M AgriLife. In response to the spread, Pennsylvania and New Jersey have issued quarantine orders, increased monitoring, and urged farmers and pet owners to inspect wounds and report any infestations.

Overall, the coordinated federal, state and industry effort seeks to protect livestock health, safeguard the food supply and prevent potentially billions of dollars in economic losses.
