SHIC-FUNDED SYSTEMATIC LITERATURE REVIEW REVEALS JEV KNOWLEDGE GAPS

Due to the ongoing risk of Japanese encephalitis virus emergence in the US, the Swine Health Information Center funded a systematic literature review intended to increase understanding of the virus’s biology, components and dynamics of transmission, and environmental factors necessary for incursion and establishment. The recently completed systematic review is in addition to a separate JEV Risk Assessment funded by SHIC that is still in progress. As the US is considered a susceptible region with potential for the introduction of JEV, SHIC has focused on these projects designed to further strengthen US swine industry preparedness and inform response efforts, should they be needed.

Led by Dr. Natalia Cernicchiaro, Kansas State University, and in collaboration with researchers from the United States Department of Agriculture National Bio and Agro-Defense facility and the National Feral Swine Damage Management Program, the study synthesized existing information on the role of domestic and feral swine in the transmission of JEV through a systematic review of 228 articles deemed relevant in a process designed to identify knowledge gaps.

The Next Mile, host Dr. Meredith Petersen, Director of Swine Health at the National Pork Board, sits down with Dr. Cara Haden, Director of Animal Welfare and Biosecurity at Pipestone, to unpack the National Swine Health Strategy and what it means for producers across the country.

Meredith walks through how the strategy came together: a producer-led effort launched in March 2025 in response to input gathered at the National Pork Industry Forum, built around two core goals, keeping foreign and emerging diseases out of the U.S. herd and reducing the impact of domestic diseases already here, including long-term elimination targets for PRRSV and PEDV.

Cara then brings the conversation down to the farm level, sharing how Pipestone scores biosecurity across seven key areas: air, feed, water, people, supplies, trucks and pigs, plus everything within the farm perimeter. She and Meredith dig into why farm leadership and daily culture, not just protocols on paper, ultimately determine whether biosecurity efforts stick.

Whether you're a producer, veterinarian, or anyone invested in herd health, this episode offers a grounded look at where the industry is headed and what everyday habits make the biggest difference.
