Understanding PEDV: How Feed Plays a Role in Prevention

In this podcast, Dr. Francisco Domingues unpacks the complex challenge of Porcine Epidemic Diarrhea Virus (PEDV), a highly contagious disease that continues to impact swine production due to its rapid spread and severe impact on piglet mortality. While farm-level biosecurity is well-known, feed has emerged as a critical but often overlooked vector for PEDV transmission. Research shows that PEDV can survive in certain feed ingredients—especially those of animal origin or with high moisture content—making the entire supply chain a point of vulnerability. Dr. Domingues emphasizes the importance of practical interventions, such as thermal processing, use of feed mitigants, and strict transport protocols to reduce contamination risk.
