New World Screwworm Resources

Overview

New World screwworm (NWS) is a serious pest of livestock and wildlife. USDA is leading a coordinated One Health response to combat NWS. This is not a food safety issue—the U.S. food supply remains safe. The current risk to animals and people in the United States is very low.
