CDC activates emergency response to screwworm infestations
Federal officials say 110 USDA staffers and millions of sterile flies are being deployed to stop the parasite’s spread.
- On Friday, the U.S. Department of Health and Human Services activated the Centers for Disease Control and Prevention emergency response at level 3 to coordinate containment of the New World Screwworm outbreak.
- The parasite spreads when female flies lay eggs in open wounds, with USDA tracking showing at least nine cases across Texas and New Mexico affecting cattle, goats, and a dog.
- Agriculture Secretary Brooke Rollins reported 110 full-time USDA staffers are working on the problem, while the FDA approved Generic Nitenpyram tablets for cats and dogs weighing at least two pounds and at least four weeks old.
- Colorado implemented new inspection and transportation rules to prevent spread, with state veterinarian Maggie Baldwin noting the response to one case can be "very robust" and "very intensive."
- While the risk to humans is rare, the CDC documented one human infection in 2025 when a traveler returned from Central America, underscoring the need for monitoring exposure during the current outbreak.
