“A case of New World screwworm has been found in Texas six decades after the flesh-eating pest was largely eradicated in the United States, sparking an aggressive response amid fears about its potential impact on the livestock industry. The U.S. Agriculture Department confirmed the parasite was detected in the umbilical area of a 3-week-old calf in Zavala County. There have been no further cases detected, and efforts are underway to contain and eradicate it, the agency said in a statement Wednesday. New World screwworm is a parasitic fly that affects livestock, pets and wildlife, as well as people in rare cases. It lays eggs in open wounds or orifices, with the hatched maggots burrowing into and feeding on flesh. It’s typically found in South America and parts of the Caribbean but has moved north through Central America and Mexico since 2023, according to the Centers for Disease Control and Prevention.” (06/04/26)
