This month we sat down with Dr. Rosemary Sifford - Deputy Administrator and Chief Veterinary Officer for USDA-APHIS to discuss a zoonotic health threat that is creeping closer to the United States: New World Screwworm. Dr. Sifford explains what New World Screwworm is, why it is a threat to US livestock, and what veterinarians should do if they suspect they are dealing with an infected animal. Veterinarians play a key role in surveillance for diseases such as NWS and early reporting is imperative.

*Note: There are no known cases of NWS in livestock in the US as of the publication of this podcast.*
