On June 3, 2026, the U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) confirmed the detection of a New World screwworm in Texas—the first of its kind in the country.
Officials identified worm larvae in the umbilical area of a 3-week-old calf. To date (6/4/26), there have been no further detections.
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 to livestock and economic losses.
If the presence of screwworm is suspected in samples received at the University of Minnesota Veterinary Diagnostic Laboratory locations in St. Paul or Willmar, they will be forwarded to the National Veterinary Services Laboratory (NVSL) within 24 hours for evaluation.
