Flesh-eating screwworms head for American livestock

Federal and state officials are preparing for a potential New World screwworm invasion near the U.S.-Mexico border, which could disrupt livestock markets and raise beef prices. A ban on Mexican cattle imports and sterilization efforts are underway, but experts warn eradication may be challenging. Beef prices have already surged 77% since January 2020 due to supply shortages and high demand.
