Michigan Urges Continued Vigilance Against Avian Influenza for Bird Owners

By Andi Anderson

While the Michigan Department of Agriculture and Rural Development (MDARD) reports no new cases of highly pathogenic avian influenza (HPAI) in domestic poultry flocks since December 2023, the virus persists in wild birds across the United States and Michigan. MDARD urges bird owners to remain vigilant and take preventive measures to ensure the health of domestic flocks.

Dr. Nora Wineland, DVM, MS DACVPM, the State Veterinarian, emphasizes the continued risk posed by HPAI, especially with the ongoing spring migration of wild birds. Wild birds can carry and spread the disease, making it crucial for bird owners to prioritize protective measures.

Since the detection of Michigan's first case of HPAI in a domestic flock on February 24, 2022, MDARD has received numerous calls and conducted investigations. Out of 93 investigations, 29 infected flocks were detected, spanning backyard, hunting preserves, and commercial flocks in 18 counties.

Despite no new domestic cases in 2024, MDARD has already responded to calls regarding sick or dead domestic birds. Two potential cases were investigated, both testing negative for HPAI. The public health risk, according to the U.S. Centers for Disease Control and Prevention, remains low, with assurance that infected birds or products will not enter the commercial food chain.

MDARD underscores the importance of preventive measures for all bird owners, regardless of flock size. Key steps include:

Prevent Contact with Wild Birds:

• Bring birds indoors or ensure outdoor areas are fully enclosed.

Personal Hygiene:

• Wash hands before and after handling birds.
• Disinfect boots and gear when moving between coops.

Equipment and Supply Management:

• Avoid sharing equipment between coops or farms.
• Clean and disinfect equipment between uses.

Water and Feed Security:

• Use well or municipal water for bird drinking.
• Secure poultry feed to prevent contact with wild birds or rodents.

MDARD commits to monitoring national HPAI trends, receiving and responding to reports of sick or dead domestic birds, and collaborating with state and federal agencies. Bird owners are encouraged to report any signs of avian influenza in domestic birds promptly.

Reporting Possible Cases:

• For Domestic Birds: If avian influenza is suspected, contact MDARD immediately at 800-292-3939 (daytime) or 517-373-0440 (after-hours).
• For Wild Birds: Report unusual or unexplained deaths among wild bird populations to the Michigan Department of Natural Resources (DNR) through the Eyes in the Field app or by calling the DNR Wildlife Disease Laboratory at 517-336-5030.
