As the holiday season approaches, Eastern Iowa is facing an unsettling development: H5N1 avian influenza has been confirmed in turkey farms in Minnesota and appears to be moving into our region. This resurgence of bird flu-first detected in 2022-is happening right as demand for turkeys peaks.
During the devastating 2015 outbreak, transmission of avian flu was largely farm-to-farm. Today’s situation looks different. According to poultry experts, the virus seems to be moving south with the fall bird migration. As migratory birds land in the Midwest, they can carry the virus to local farms-especially those with high-density poultry populations.
Compared to chickens and ducks, turkeys are more susceptible to H5N1. Part of this vulnerability comes from how turkeys are raised. As Dr. Yuko Sato of Iowa State University notes, turkeys are typically floor-raised rather than caged. This management style can accelerate virus spread between birds and flocks, making biosecurity harder to enforce.
Since the 2015 outbreak, producers have strengthened biosecurity to keep farm-to-farm transmission low. These measures include:
Stricter health screenings for new birds entering the flock
Physical barriers to keep wild or external birds away from barns
Segregating or culling infected flocks to prevent virus spread and keep infected birds out of the food chain
Thanks to these protocols, farms are far better prepared now than they were a decade ago. But preparedness does not equal immunity.
If the virus continues spreading south, we may see an impact on turkey prices before Thanksgiving. Early detection offers some hope-if the virus peaks quickly, the fallout may be limited. However, a sustained outbreak through fall and winter could lead to significant supply disruptions and higher prices for consumers.
H5N1 isn’t only about poultry economics. Avian flu can cause:
Mass bird die-offs, affecting wild bird populations and ecosystems
Severe illness in poultry, leading to large-scale culling and economic loss
Limited but real risk of cross-species transmission, especially to humans working closely with infected birds
While the current strain poses a very low risk to the general public, experts keep a close eye on mutations that could make the virus more easily transmissible to humans.
Rachel Ruden, state wildlife veterinarian for the Iowa DNR, notes that this year’s early activity could “burn bright but short” or persist well into the winter. Either way, producers are far more knowledgeable and proactive than in 2015. Vigilance, strict biosecurity, and rapid response remain the best defenses.
Migrating wild birds remain a significant vector for H5N1
Turkeys are more susceptible than other poultry, making farms higher-risk zones
Biosecurity measures can’t be relaxed even during “low-risk” seasons
Price fluctuations are possible heading into Thanksgiving and the winter holidays
Bottom Line: H5N1 is back on the radar in Eastern Iowa. While farms are better prepared than before, the combination of migration patterns, turkey vulnerability, and high holiday demand creates a challenging situation. Staying informed-and supporting producers’ biosecurity efforts-can help mitigate the risks to both agriculture and public health.
