Abstract: Shortening Duration of Swine Exhibitions to Reduce Risk for Zoonotic Transmission of Influenza A Virus

Sep 23, 2022

Reducing zoonotic influenza A virus (IAV) risk in the United States necessitates mitigation of IAV in exhibition swine. We evaluated the effectiveness of shortening swine exhibitions to <72 hours to reduce IAV risk. We longitudinally sampled every pig daily for the full duration of 16 county fairs during 2014-2015 (39,768 nasal wipes from 6,768 pigs). In addition, we estimated IAV prevalence at 195 fairs during 2018-2019 to test the hypothesis that <72-hour swine exhibitions would have lower IAV prevalence. In both studies, we found that shortening duration drastically reduces IAV prevalence in exhibition swine at county fairs. Reduction of viral load in the barn within a county fair is critical to reduce the risk for interspecies IAV transmission and pandemic potential. Therefore, we encourage fair organizers to shorten swine shows to protect the health of both animals and humans.

Video: Biosecurity Compliance - Dr. Jean-Pierre Vaillancourt

In this episode of The Swine it Podcast Show Canada, Dr. Jean-Pierre Vaillancourt, professor of veterinary medicine at the University of Montreal, discusses the human side of biosecurity compliance. He explains why protocols often fail when people are tired, unconvinced, undertrained, or working with impractical systems, and how leadership, employee input, technology, feedback, and small incentives can make biosecurity more consistent on swine farms. Listen now on all major platforms!

"Biosecurity only works when people repeatedly do the right thing, and that means the system has to support compliance every day."

Meet the guest: Dr. Jean-Pierre Vaillancourt is a veterinarian and professor of veterinary medicine at the University of Montreal. His work focuses on biosecurity, infectious disease control, and practical risk reduction in animal production systems, with experience across swine and poultry health.
