The state of Texas has declared a state of disaster following the confirmation of the first case of New World screwworm, a dangerous pest that infests living tissue of warm-blooded animals. The announcement was made on June 5, 2026, by state officials after the U.S. Department of Agriculture confirmed the presence of the screwworm in a local animal.
What Is New World Screwworm?
The New World screwworm (Cochliomyia hominivorax) is a fly species whose larvae feed on the living tissue of mammals, including livestock, pets, and occasionally humans. Infestations can be fatal if untreated. The fly is native to parts of South America and has been largely eradicated from the U.S. and Central America through sterile insect release programs.
Response Measures
Texas authorities have activated emergency protocols to contain and eradicate the pest. Measures include increased surveillance, quarantine zones, and public awareness campaigns. The U.S. Department of Agriculture is coordinating with state agencies to deploy sterile flies and treatment resources.
- Quarantine areas established around the detection site.
- Livestock inspections intensified across the state.
- Public urged to report any signs of screwworm infestation in animals.
The disaster declaration allows the state to access additional funding and resources to combat the outbreak. Officials emphasize that while the risk to humans is low, precautions should be taken to protect animals.
Impact on Agriculture
Texas is a major livestock producer, and the screwworm outbreak poses a significant economic threat. The pest can cause severe losses in cattle, sheep, and other animals. Ranchers are advised to check animals regularly for wounds and signs of infestation, such as larvae in open sores.
The last major screwworm outbreak in the U.S. occurred in the 1960s before eradication efforts succeeded. This case marks a potential setback, but authorities are confident that swift action will prevent widespread spread.
