New World screwworm (NWS) has officially landed on U.S. soil, ending more than six decades without the destructive livestock pest and putting dairy producers on alert.

USDA recently confirmed a case in South Texas near La Pryor. The infestation was identified in a 3-week-old calf and confirmed by USDA’s National Veterinary Services Laboratories in Ames, Iowa. Federal animal health officials have activated response efforts as they work to contain the pest and prevent further spread.
