Michigan officials confirm avian influenza (aka Bird Flu) in a commercial flock, stressing biosecurity and prevention for both animals and humans.
Ottawa County Reports First Avian Influenza Case Since May
LANSING – The Michigan Department of Agriculture and Rural Development (MDARD) has confirmed a new case of Highly Pathogenic Avian Influenza (HPAI) in a commercial poultry facility in Ottawa County. This marks the first detection of the disease in Michigan since May 2024 and the second case in Ottawa County since 2022.
Officials emphasize that biosecurity measures remain critical to containing the virus and protecting both animal and public health. MDARD Director Tim Boring underlined the importance of vigilance. “Slowing the spread of HPAI to protect human health is a top priority. Expanding biosecurity and surveillance efforts are key strategies to prevent domestic infection and broader human threats.”
Virus Transmission and Containment Measures Underway
HPAI, a highly contagious virus, spreads easily through wild birds, infected animals, contaminated equipment, or caretakers’ clothing and shoes. The affected facility is currently under quarantine, and all birds will be depopulated to prevent the spread of the disease. Officials stress these measures also ensure the safety of the commercial food supply.
State Veterinarian Dr. Nora Wineland highlighted the seasonal risks. “Cold weather and HPAI circulation in wild bird populations create ideal conditions for virus spread. Keeping domestic animals isolated and maintaining strict cleanliness are essential.”
The U.S. Centers for Disease Control and Prevention (CDC) has assessed the public health risk as low. HPAI-infected birds or products will not enter the commercial food chain. Nevertheless, health experts recommend properly handling and cooking all poultry and eggs as a standard precaution.
Biosecurity Measures Urged for Poultry Owners
Farmers and backyard bird owners are urged to follow key preventative measures to protect domestic flocks:
- Prevent contact between domestic and wild birds by bringing poultry indoors or enclosing outdoor areas.
- Wash hands before and after handling birds and between coop visits.
- Disinfect boots, gear, and equipment to limit contamination.
- Avoid sharing tools or supplies between flocks or farms.
- Use clean well or municipal water as a drinking source.
- Keep poultry feed protected from wild birds and rodents.
MDARD officials are coordinating closely with local, state, and federal agencies to respond quickly to new reports and limit the spread.
How to Report Sick Birds and Potential Cases
MDARD encourages bird owners to watch for signs of avian influenza, including sudden deaths, decreased egg production, significant drops in water intake, diarrhea, coughing, or multiple sick birds. Suspected cases in domestic birds should be reported immediately to MDARD at 800-292-3939 (daytime) or 517-373-0440 (after hours).
For wild bird concerns, individuals can report unusual or unexplained deaths to the Michigan Department of Natural Resources (DNR) by:
- Using the DNR’s Eyes in the Field app and selecting “Diseased Wildlife.”
- Calling the DNR Wildlife Disease Laboratory at 517-336-5030.
