LUBBOCK, Texas (RFD News) — Nearly 60 years after New World Screwworm disappeared from U.S. livestock, ranchers are again being asked to serve as the first line of defense.
American Farm Bureau Federation economists say confirmed cases in Texas and New Mexico show the risk of northward movement from Mexico. The pest does not threaten food safety, but it can infest wounds in cattle, sheep, goats, wildlife, pets, and other warm-blooded animals.
The analysis says early detection is critical. Producers are urged to inspect animals daily, treat wounds quickly, and call a veterinarian immediately if they suspect an infestation.
Containment is complicated by large ranches, wildlife movement, small ruminants, and the limited supply of sterile flies used to suppress the pest. USDA response actions include quarantine zones, trapping, outreach, and expanded sterile fly production.
The bigger challenge may be trust. Farmers and ranchers need support if reporting brings quarantine costs or market losses.
