A pest that many producers thought was confined to the history books is making headlines again. In this episode, Dr. Colt Knight sits down with Ashley Wright of the University of Arizona Cooperative Extension to discuss New World screwworm, a devastating livestock pest that has reemerged in North America. They explain what screwworm is, how it differs from ordinary fly strike and why veterinarians and livestock producers are taking the threat so seriously.
The conversation covers the history of screwworm eradication, recent cases detected in the southern United States, impacts on cattle markets and cross-border livestock movement, and practical steps producers can take to protect their animals. From wound management and biosecurity to sterile fly control programs, this episode provides timely information every livestock owner should know as the industry works to prevent another major outbreak.
