Senecavirus A (Seneca Valley Virus) in Swine

Aug 07, 2015

Recently, there have been 4 cases of vesicular disease observed in unrelated diagnostic case submissions (3 cases from exhibition swine in Iowa, 1 case from a commercial finishing operation in South Dakota) at the ISU-VDL since July 28, 2015. Foreign animal disease investigations were initiated and samples all tested negative to FMDV, but positive to Senecavirus A. Other vesicular diseases have been ruled out as well. AASV originally reported on the presence of Seneca Valley Virus in October 2012. That article describing the clinical presentation associated with earlier introductions can be accessed on the AASV website. In addition, Drs. Chris Rademacher, Darin Madson, Rodger Main, KJ Yoon, Daniel Linhares, and AJ Smit at Iowa State University Veterinary Diagnostic Lab have compiled a fact sheet entitled Senecavirus A (Seneca Valley Virus) in Swine describing the virus and clinical presentation of the recent cases. This document can be viewed on the AASV website by clicking here.

Video: What Really Drives Meat Quality in Pork? - Dr. Yan Huang

In this episode of The Swine it Podcast Show Canada, Dr. Yan Huang from University of Arkansas explores how genetics, nutrition, and stress management shape pork quality. He explains how molecular pathways influence fat deposition, muscle growth, and meat flavor while balancing production efficiency. Listen now on all major platforms!

"The most important driver of pork quality. Feed plays a very important role in the meat quality."

Meet the guest: Dr. Yan Huang / yan-huang-77829421 is an Associate Professor in Nutritional Skeletal Muscle Biology at the University of Arkansas. With academic experience across China, South Korea, and the United States, his work focuses on the genetic and molecular regulation of muscle growth and fat deposition in swine. His research connects genetics, nutrition, and pork quality to improve production efficiency and consumer satisfaction.
