The Swine It Podcast: Dr. Declan Schroeder - Stronger Biosecurity with Viability PCR

Dr. Declan Schroeder, Professor of Virology at the University of Minnesota, explains how viability PCR improves virus detection in swine systems. He discusses how this molecular approach distinguishes intact virus particles from residual genetic material, helping evaluate biosecurity risks, feed contamination, and mitigation strategies. Dr. Schroeder also highlights how the method supports better decision-making in disease prevention.
