The New World Screwworm (NWS)— a parasitic pest eradicated from the U.S. in 1966— is climbing north from Panama, and getting a little too close to the homeland. Secretary of Agriculture Brooke Rollins closed the U.S./Mexican border for live imports of cattle, equine and bison for a second time this year as eradication protocols ramp up in Central and South America. Alabama State Veterinarian Dr. Tony Frazier with the Alabama Department of Agriculture & Industries joined host Erin Beasley in studio to discuss this pest and the measures it will take to keep it out of the U.S. cowherd.
