New World Screwworm Emergency Response
NWS Outbreak in Central America and Mexico
APHIS is partnering with other USDA agencies, the U.S. Department of State, the Food and Agriculture Organization of the United Nations, and affected countries to respond to an outbreak of NWS in Central America and Mexico.
The materials on this page are specific to New World screwworm (NWS). You can use these tools and resources to prepare for and respond to an outbreak of this pest.
We also offer general materials that apply not only to NWS, but other foreign animal pests and diseases as well. To view these materials, visit Foreign Animal Disease Preparedness and Response.
