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: Advancing Swine Disease Traceability: USDA's No-Cost RFID Tag Program for Market Channels

On-demand webinar, hosted by the Meat Institute, experts from the USDA, National Pork Board (NPB) and Merck Animal Health introduced the no-cost 840 RFID tag program—a five-year initiative supported through African swine fever (ASF) preparedness efforts. Beginning in Fall 2025, eligible sow producers, exhibition swine owners and State Animal Health Officials can order USDA-funded RFID tags through Merck A2025-10_nimal Health.

NPB staff also highlighted an additional initiative, funded by USDA Animal and Plant Health Inspection Service (APHIS) Veterinary Services through NPB, that helps reduce the cost of transitioning to RFID tags across the swine industry and strengthens national traceability efforts.

Topics Covered:

•USDA’s RFID tag initiative background and current traceability practices

•How to access and order no-cost 840 RFID tags

•Equipment support for tag readers and panels

•Implementation timelines for market and cull sow channels How RFID improves ASF preparedness an
