The U.S. Department of Agriculture has confirmed a case of New World screwworm in South Texas.
The Wednesday night confirmation came hours after the USDA announced earlier in the day that there was a possible case in South Texas, with National Veterinary Services Laboratories in Ames, Iowa, working to confirm it.
According to the USDA, the detection of the parasitic fly in a 3-week-old calf in Zavala County, Texas, was confirmed, the only U.S. detection so far. Larvae were identified in the calf’s umbilical area.
