The U.S. Department of Agriculture (USDA) announced in April that the New World Screwworm (NWS) is closer to the Texas border than ever before in this latest outbreak. On April 20 Texas Agriculture Commissioner Sid Miller warned, “The threat of the New World screwworm is creeping dangerously close to our border. A confirmed case in Nuevo León, just about 60 miles from the United States, in a young calf is a flashing red warning sign we will not ignore.”
