RANCH BEAT: New World Screwworm Is Back

from UNWON with Keely Covello · host Keely Covello

The flesh-eating parasite the U.S. wiped out 60 years ago is back across the border, and suddenly everyone has a PhD in parasitology.This episode of Ranch Beat covers the facts: what New World Screwworm actually is, how it clawed its way back up through Central America and Mexico, steps the USDA is taking to address it, and why some of the loudest voices online are doing real damage with bad information. Dr. Brazil, a large animal veterinarian of almost 40 years, walks ranchers through exactly what to watch for, how to treat it, and what really happens when APHIS shows up at the gate. And they end where these stories always should: not with the grandstanders, but with the rancher who caught that very first case by paying close enough attention to a newborn calf. The quiet, daily care that the people who actually do this work never stop giving.Show NotesSponsored by Ranch Vision: www.ranchvision.ioSpecial thanks to Josh Woolwine for creating our intro.
