On June 3rd, New World screwworm (NWS) was detected in a 3 month calf in Zavala County, Texas. NWS is a serious pest that affects livestock, pets, wildlife, and less commonly, people and birds. NWS larvae (maggots) burrow into the flesh of living animals, causing serious damage and economic losses to livestock producers.
