Screwworm is officially back in the U.S. A juvenile cow in Zavala County, Texas, was found to be infected by the flesh-eating parasite, which can infect livestock (and occasionally, humans). It was previously eliminated here in 1966. @sciam.bsky.social 🧪 www.scientificamerican.com/article/a-fl...
This marks the first case of the New World screwworm in U.S. livestock since the parasite was eliminated in the country in the 1960s
