The Michigan DNR’s ongoing disease surveillance indicates that HPAI is widespread in wild bird populations throughout the state.

More than 300 dead wild birds have been collected by Michigan's Department of Natural Resources in 2025. Avian flu is suspected in the mass deaths.

More than 300 dead geese and other waterfowl have been discovered in five counties, and bird flu is likely to blame, officials say.

An investigation into two severe H5N1 illnesses in exclusively indoor cats found that they may have been exposed by symptomatic dairy workers, scientists from the US Centers for Disease Control and Prevention (CDC) and their partners in Michigan reported today in Morbidity and Mortality Weekly Report.

The Department of Natural Resources confirmed highly pathogenic avian influenza, or bird flu, was found in a merganser recovered in early February along the Lake Michigan shoreline in Milwaukee County.

Michigan’s biggest egg producer is advocating for the vaccination of egg-laying hens against the highly pathogenic avian influenza. Herbruck’s Poultry Ranch CEO Greg Herbruck has called on the federal government to take “urgent and critical” measures to address the H5N1 bird flu crisis by implementing an aggressive vaccination strategy.

A growing number of wild birds are being found dead in Michigan, believed to have contracted the bird flu that’s decimated commercial poultry farms nationwide.

As H5N1 avian flu outbreaks in commercial and backyard poultry across the United States continue at a brisk pace, the US Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) has reported a few more detections in domestic cats.

HPAI spreads easily among birds and – while rare – can spread from birds to people. The U.S. Centers for Disease Control and Prevention considers the risk to people from HPAI viruses to be low.
