Flesh-eating parasite detected in South Texas, only the 3rd US case of screwworm in decades

The New World screwworm fly has reached South Texas, the U.S. Department of Agriculture confirmed Wednesday, the first time in decades that the parasite with flesh-eating larvae has threatened the nation's cattle industry and only the third time it's appeared in the U.S. in that time. Agriculture Secretary Brooke Rollins said the case was in a 3-week-old calf in LaPryor, Texas, about 50 miles (80 kilometers) from the Mexico border. Texas State Veterinarian Bud Dinges said he has established a 12-mile (20-kilometer) quarantine zone, prohibiting the movement of any warm-blooded animal — including pets — outside that zone without an inspection. Rollins said there have been no other detections of the fly in the U.S., and officials were quick to say that while the fly's larvae are a threat to livestock production, they don't infest food. Properly treated, even the infested calf should recover, Rollins said.
