Highly pathogenic avian influenza (H5N1) cases are rising across the United States, with recent outbreaks affecting both commercial and backyard poultry flocks. In the past month, 29 outbreaks have been confirmed, impacting more than 1.3 million birds and raising concerns for poultry producers according to University of Minnesota's Stephanie Soucheray, MA.
The virus has caused several significant outbreaks in the Midwest. Commercial turkey operations in Minnesota, Wisconsin and North Dakota reported infections affecting thousands of birds, highlighting the continued risk facing the turkey industry.
The largest outbreak reported in October occurred at a commercial egg-laying farm in Illinois, where more than 934,000 chickens were affected. The case accounted for a large share of the birds impacted during the recent surge in infections.
Wild birds continue to play an important role in spreading avian influenza as seasonal migration increases. Their movements can introduce the virus into domestic poultry flocks, particularly in areas along major migratory routes.
Several new backyard flock infections have also been reported on the West Coast, including cases in California and Washington. Backyard poultry operations remain vulnerable when birds come into contact with wild waterfowl or contaminated environments.
California has recorded multiple H5N1 detections in wild birds, including Canada geese and American white pelicans. These findings are consistent with the increased disease activity often seen during migration seasons.
Animal health officials are encouraging producers to closely monitor flock health and strengthen biosecurity practices. Preventing contact between domestic poultry and wild birds remains one of the most important measures for reducing infection risks.
