A single case of New World screwworm has been confirmed in a calf in La Pryor, Texas, marking the first U.S. detection in decades. This has placed ranchers and pet owners on edge, with concerns about potential decimation of cattle herds and local wildlife. The U.S. Department of Agriculture (USDA) is leading containment efforts, deploying workers to set fly traps, release sterile flies, and inspect livestock at checkpoints. Fears of further infestations have contributed to a rally in U.S. cattle futures. While the USDA stated efforts by the Trump administration had staved off the parasite's arrival until recently, some local officials and ranchers have criticized the agency's preparedness and response. Kinney County has declared a disaster, and calls have been made for Texas Governor Greg Abbott to do the same to trigger federal relief funds.
