Avian Influenza Detected in Michigan's Ionia County

By Andi Anderson

The detection of highly pathogenic avian influenza (HPAI) in a commercial poultry facility in Ionia County, Michigan, underscores the importance of preventive measures as wild birds complete their spring migration. This marks the fourth detection of HPAI in a commercial facility since its initial discovery in Michigan in 2022 and the first in Ionia County.

Dr. Nora Wineland, State Veterinarian, stresses the critical need for vigilance, particularly as cool weather persists and wild birds continue their migratory journey. Preventative measures remain paramount to keep HPAI out of Michigan's domestic animal population.

HPAI is highly contagious and spreads through various channels, including contact with infected poultry, wild birds, equipment, and even caretakers' clothing and shoes. The affected premises in Ionia County is currently under quarantine, with depopulation efforts underway to curb disease spread and safeguard the commercial food supply.

Dr. Nancy Barr, executive director of Michigan Allied Poultry Industries, commends the proactive stance of Michigan's egg farmers and emphasizes the importance of strict biosecurity measures in preventing HPAI transmission.

Detection of HPAI, the public health risk remains low, according to the U.S. Centers for Disease Control and Prevention. Additionally, no infected animals or products will enter the commercial food chain. However, proper handling and cooking of all food items are advised.

To protect Michigan's domestic bird population, whether backyard flocks or commercial operations, adherence to key biosecurity measures is imperative:

• Prevent contact between domestic and wild birds.
• Maintain proper hand hygiene before and after handling birds.
• Disinfect equipment and footwear when moving between coops.
• Avoid sharing equipment between coops or farms.
• Ensure secure poultry feed storage to prevent contact with wild birds or rodents.

MDARD continues to collaborate with local, state, and federal partners to swiftly respond to HPAI reports and provide necessary outreach. Domestic bird owners and caretakers are urged to remain vigilant and report any suspicious symptoms promptly to MDARD.

For potential cases involving wild birds, citizens are encouraged to report unusual or unexplained deaths to the Michigan Department of Natural Resources via the Eyes in the Field app or by contacting the DNR Wildlife Disease Laboratory.
