Screwworm Resurgence Threatens Livestock
Description
A nasty parasite thought to be eradicated for decades has made a shocking comeback in the Southwestern U.S., threatening livestock and causing major financial losses. The New World screwworm lays eggs in open wounds, and the maggots burrow in to eat flesh, causing painful, smelly sores. North Carolina has tightened animal import rules to stop the spread, following confirmed cases in Texas and New Mexico. Experts debate how it returned, with some blaming federal staffing cuts, while officials credit cooperation with Mexico and state partners. Thankfully, early treatment usually saves animals — though severe cases may require euthanasia. Humans can get infected too, but it’s rare. If you spot maggots, foul odors, or signs of pain in your animals, call your vet or agricultural department immediately — this is a reportable disease.
