The first U.S. case of the New World screwworm fly in 60 years has been detected in a calf near the Texas-Mexico border, prompting a livestock quarantine and urgent containment efforts by the U.S. Department of Agriculture (USDA). The flesh-eating parasite, which can decimate cattle herds and local wildlife, was found in La Pryor, Texas. Texas Governor Greg Abbott declared a state of disaster, urging the federal government to accelerate the construction of a sterile fly production facility, which is critical for preventing spread during the summer months. Canada has imposed temporary import restrictions on livestock from Texas. USDA workers are fanning out across Zavala County to release sterile flies and inspect animals. Ranchers and pet owners are on edge, with fears of further infestations impacting the cattle industry.
