U.S. Beef Industry Faces Screwworm Risk After Program Cuts

Background on the threat Screwworm is a parasitic fly whose larvae feed on the living tissue of warm-blooded animals, including cattle. An unchecked outbreak can cause rapid herd losses and require extensive treatment and quarantine measures.

Current status No confirmed cases have been reported in Texas or elsewhere, according to the post. The absence of routine surveillance means any new infestation would likely be identified only after visible symptoms appear in herds. The post notes that earlier detection historically relied on systematic inspection and laboratory testing now discontinued.
