Officials confirmed three new cases of New World screwworm in Texas, prompting efforts to contain the parasite that threatens livestock.
TEXAS, USA — Three new cases of the New World screwworm have been confirmed in Texas as state and federal officials continue efforts to contain the parasite and prevent its spread.
The U.S. Department of Agriculture (USDA) announced Sunday that the latest cases were found in a lamb in Crockett County and two calves in Edwards County. The new detections bring the total number of confirmed New World screwworm cases in the United States this year to 15.

The New World screwworm is a parasitic fly whose larvae feed on the living tissue of warm-blooded animals. The pest can infest cattle, sheep, goats, deer, pets and other wildlife. In rare cases, it can also affect people.
According to the USDA, the three newest Texas cases were identified through ongoing surveillance efforts. Officials say early detection and rapid treatment remain critical to limiting the parasite’s spread.
To combat the outbreak, the USDA is releasing millions of sterile male flies. The strategy is designed to prevent the pests from reproducing, helping reduce populations and stop the infestation from expanding into new areas.
The agency says it will continue monitoring for additional cases across Texas and other southern states.
State and federal officials are urging ranchers and livestock producers to regularly inspect animals for unusual wounds or signs of infestation and report suspected cases immediately so investigators can respond quickly.
