New World Screwworm Spreads Beyond Texas, Threatening U.S. Cattle Industry
The USDA confirms three additional New World screwworm cases, including one in New Mexico, signaling the parasite’s spread beyond Texas. Authorities have quarantines around affected areas and are ramping up sterile‑male fly releases as part of a long‑term program to halt the outbreak, while researchers seek faster sterile‑fly production and a potential Texas fly factory. Beef prices remain steady for now, but the parasite threatens the U.S. cattle industry if containment fails.
