Texas Screwworm Outbreak Reaches 16 Animal Cases as Farm Workers Face Higher Spillover Risk

Summary
Sixteen screwworm cases have now been confirmed in goats and sheep across three Texas counties, with no human infections reported so far.
Agricultural workers face the highest human exposure risk because the fly lays eggs in even tiny wounds and is concentrated around livestock, yet many workers live and work in conditions that increase contact.
Long hours, remote housing, lack of insurance, language barriers and fear tied to immigration enforcement can delay treatment and keep workers out of disease surveillance, clinicians said.
The outbreak's main economic threat is to the $347.7 billion U.S. meat and poultry industry; the FDA has authorized emergency animal antiparasitic use as ranchers step up wound care, protective clothing and livestock treatment.
Producers say containment will require aggressive response in herds, sterile-fly deployment and coordination with Mexico and Central American countries to push the parasite back south.
