Dear Honorable Tribal Leaders, program personnel, and community members,  

The U.S. Department of Agriculture, Animal and Plant Health Inspection Service (APHIS) greatly values its partnerships with Tribal Nations and communities.

To keep Tribal Nations abreast of USDA news and updates, the APHIS Office of National Tribal Liaison is hosting a Tribal Nations-exclusive webinar on New World screwworm (NWS).

NWS is a serious pest of livestock, pets, and wildlife. USDA is leading a coordinated One Health response to combat NWS.
