The U.S. Department of Agriculture (USDA) on Monday confirmed two additional cases of New World screwworm in Texas, widening a multi-agency response that has already triggered international trade restrictions. The latest cases involve a calf in La Salle County and a dog in Andrews County. According to the USDA’s Animal and Plant Health Inspection Service (APHIS), preliminary investigations indicate the infested dog had recently been in Mexico, where the parasite is known to be present. With these new detections, federal officials have now confronted four confirmed cases of the flesh-eating pest over the past week.
