USDA: Flesh-eating screwworm found in Texas calf, containment zone established
The USDA confirmed a New World screwworm infection in a 3-week-old calf in Zavala County, Texas, and launched a 12-mile infested zone with quarantines, border traps, and an Incident Command Team to eradicate the parasite; a sample is being validated by the NVSL, and authorities note thousands of cases in Mexico and the potential risk to livestock and rare human infections.
