LANSING, MI—Following an investigation by the Michigan Department of Agriculture and Rural Development (MDARD), the Michigan State University Veterinary Diagnostic Laboratory has detected the presence of highly pathogenic avian influenza (HPAI) in a backyard flock from Ontonagon County. This is the first case of HPAI in poultry from an Ontonagon County flock since the virus was first detected in Michigan in 2022, and the first case in Michigan’s Upper Peninsula since the spring of 2022 when four infected backyard flocks were found in Menominee County. Adhering to biosecurity measures and using personal protective equipment (PPE) continue to be vital in helping ensure the health of Michigan’s domestic animals and the general public.
HPAI is a highly contagious virus that can be spread in various ways from flock to flock, including by wild birds, through contact with infected animals, by equipment, and on the clothing and shoes of caretakers.
According to the U.S. Centers for Disease Control and Prevention, the public health risk associated with avian influenza remains low. As a reminder, people should properly handle and cook all poultry and eggs.
Whether it’s a few backyard birds or a large commercial flock, following a few key steps is fundamental to protecting the health and vitality of Michigan’s domestic birds:
- Prevent contact between domestic and wild birds by bringing them indoors or ensuring their outdoor area is fully enclosed.
- Wash your hands before and after handling birds as well as when moving between different coops.
- Disinfect boots and other gear when moving between coops.
- Do not share equipment or other supplies between coops or other farms.
- Clean and disinfect equipment and other supplies between uses. If it cannot be disinfected, discard it.
- Use well or municipal water as drinking water for birds.
- Keep poultry feed secure to ensure there is no contact between the feed/feed ingredients and wild birds or rodents.
Reporting Possible Cases
For Domestic Birds
Domestic bird owners and caretakers should watch for multiple sudden deaths in the flock, a drop in egg production, a significant decrease in water consumption, diarrhea, sneezing/coughing, or an increase in sick birds. If avian influenza is suspected in domestic birds, contact MDARD immediately at 800-292-3939 (daytime) or 517-373-0440 (after-hours).
For Wild Birds
If anyone notices what appears to be unusual or unexplained deaths among wild bird populations, please report these cases to the Michigan Department of Natural Resources (DNR) by:
- Using the DNR’s Eyes in the Field app. Choose the “Diseased Wildlife” option among the selections for “Observation Forms.”
- Calling the DNR Wildlife Disease Laboratory at 517-336-5030.
Subscribe to receive email notifications by visiting MDARD’s Media Room website and clicking on the “Avian Influenza” link. After entering a valid email address, subscribers will receive updates and alerts regarding the status of avian influenza in Michigan whenever there are new developments to report. Additional resources can also be found at Michigan.gov/BirdFlu.

Highly Pathogenic Avian Influenza Detected in Ottawa County Backyard Flock
January 28, 2026
llowing an investigation by the Michigan Department of Agriculture and Rural Development (MDARD), the Michigan State University Veterinary Diagnostic Laboratory has detected the presence of highly pathogenic avian influenza (HPAI) in a backyard poultry flock from Ottawa County. This is the first detection of HPAI in a Michigan domestic flock in 2026, and the 16th case in an Ottawa County poultry flock since the virus was first detected in the state in 2022. Even with the cold temperatures, the virus is still present in the environment and travelling through infected wild birds. MDARD continues to strongly recommend owners remain vigilant and actively protect their animals from HPAI.
“While there has not been a detection of HPAI in a Michigan domestic flock since November 2025, the virus continues to circulate in wild birds, posing a risk to the state’s poultry farmers. As these birds move and migrate, their movement increases the risk of disease spread,” said State Veterinarian Dr. Nora Wineland, DVM, MS, DACVPM. “Bird owners must continue to take every preventative measure they can to protect their flocks from being exposed to wild birds and the germs they could be carrying. Keeping Michigan’s domestic birds healthy needs to remain a priority.”
