The flesh-eating New World screwworm has been confirmed in a Texas calf, marking the first detection of the parasite in U.S. livestock in decades. The Department of Agriculture announced Wednesday that a three-week-old calf in Zavala County, Texas, tested positive for New World screwworm, a parasite whose larvae feed on the living tissues of warm-blooded animals, and yes, sometimes humans. The confirmation comes one day after The Daily Wire reported on a suspected case in South Texas and follows a growing outbreak in Mexico that prompted federal officials to warn that the pest could eventually cross into the United States. According to the USDA, the screwworm infestation was found in the calf’s umbilical area. The parasite typically enters animals through open wounds, where larvae burrow into the flesh and feed on living tissue. Federal officials said no additional cases have been identified in the United States. As far as meat and produce go, the USDA noted the food supply is safe because screwworms do not infest meat, fruits, vegetables, or other food sources.
