The CDC has activated an emergency response plan for potential human cases of New World screwworm as the flesh-eating parasite spreads in animals across the U.S. Federal health officials say no locally acquired human infestations have been reported in the United States so far, but the current outbreak has already moved north through Central America and Mexico, where more than 171,700 animal cases and more than 2,070 human cases have been reported since 2023. New World screwworm larvae feed on living tissue and can infect livestock, pets, wildlife, and, in rare cases, people.
Why This Matters:
When the CDC activates an emergency response plan, it shows this is no longer just a ranching issue. A parasite that threatens livestock can also raise public health concerns, especially if it continues spreading across borders and into new areas. For households, this is another reminder that food supply and health risks are often connected. Having long-term food storage in place gives families a backup when pests, disease, or public health concerns create uncertainty around everyday food.
