It was a busy day at the youth swine exhibition as competitors, aged 3 to 21, prepared their pigs for the show ring. Amidst the bustling atmosphere, Dr. Andrew Bowman, a molecular epidemiologist at Ohio State University, made his way through the pig barn, clad in waterproof green overalls. His objective: to collect swine samples for testing.
Dr. Bowman, along with his colleagues, has been studying the dangers associated with swine shows for over a decade. Pigs have long been known as a source for novel flu variants, and outbreaks of swine flu have occurred repeatedly in the United States. By swabbing pigs at these shows, Dr. Bowman’s team has discovered a national network of events that result in human infections in a cyclical fashion.
The spread of new flu variants begins in the spring, with regional and national “jackpot” shows bringing together pigs from various farms, facilitating the spread of the virus across the country. The summer and fall see a larger number of children bringing their pigs to county or state fairs, where the risk of transmission increases due to close contact between humans and pigs.
Fairs such as these have become hotspots for zoonotic disease spread, with the pigs shedding the influenza virus and potentially infecting other animals and people. This poses a significant public health risk, as demonstrated by the 2009 swine flu pandemic that originated in pigs in Mexico and claimed thousands of lives worldwide.
Dr. Bowman and his colleagues have identified several factors contributing to the risk of transmission at swine shows. Inadequate hand sanitation practices and lack of guidance on proper usage have been noted. Additionally, the standard weigh-in procedure, in which pigs are lined up nose-to-tail, can accelerate transmission if one infected pig contaminates the common surface.
To address these issues, the researchers have shared their findings with show organizers and health officials, promoting changes such as improved signage, reducing opportunities for mingling of pigs, and implementing better biosecurity measures.
While larger shows have begun sending pigs home after 72 hours to minimize transmission risks, not all shows have been receptive to these changes. Consequently, the Ohio State team has taken a bottom-up approach by targeting young exhibitors through their Swientist program, which focuses on teaching proper biosecurity measures to keep pigs and humans healthy.
At swine shows across the country, Ohio State researchers engage with children, educating them about hand hygiene, proper use of personal protective equipment, and overall disease prevention practices. The program has proven successful, with children actively participating in activities and demonstrating an understanding of biosecurity measures.
Initially met with skepticism, the researchers have built trust within the swine exhibition community by sharing data and positioning themselves as collaborative partners. The goal is to foster a culture of biosecurity that can reduce the risk of zoonotic disease transmission at these events.
The need to address the health risks associated with swine exhibitions is a pressing concern, as zoonotic diseases continue to pose significant threats to public health worldwide. By emphasizing the importance of responsible human behavior and implementing robust biosecurity measures, researchers hope to make swine shows safer environments for both animals and participants.
As Dr. Bowman aptly states, “If it’s the next pandemic, then it’s really bad.”
