AUSTIN, Texas — **Editor's note: This story has been updated to reflect that the dog case initially reported in Andrews County, Texas, has been reclassified as the first confirmed case of New World screwworm in New Mexico, according to USDA.
New World screwworm has spread to the Texas Hill Country after federal officials confirmed a case in a Gillespie County goat Monday.
As of Monday, three calves, a dog, and a goat have confirmed cases of New World Screwworm.
The U.S. Department of Agriculture's Animal and Plant Health Inspection Service confirmed that the dog case initially reported in Andrews County, Texas, has been reclassified as the first confirmed case of New World screwworm in New Mexico. Investigators determined the dog resides in Lea County, New Mexico, though the treating veterinarian who reported the case is based in Texas.
The first two confirmed cases were calves in Zavala County in South Texas. A third calf was infected in nearby La Salle County in South Texas. But the dog in New Mexico and goat in the Texas Hill Country are spread hundreds of miles apart and have federal and state officials treating this as an aggressive emergency.
“These developments obviously represent a serious threat to our livestock and wildlife, but they have not caught us off guard. We have been tracking this pest for a long time. We have fought it off before and we will do so again,” said U.S. Secretary of Agriculture Brooke Rollins.
