Highly Pathogenic Avian Influenza Found in Ottawa County Poultry Facility

The Michigan Department of Agriculture and Rural Development (MDARD) has confirmed a case of highly pathogenic avian influenza (HPAI) in a commercial poultry operation located in Ottawa County, Michigan.

Highly Pathogenic Avian Influenza Found in Ottawa County Poultry Facility

LANSING, Mich. — This is the first reported case of HPAI in a commercial flock in Michigan since May 2024, according to an investigation by MDARD. The Michigan State University Veterinary Diagnostic Laboratory identified the presence of the virus in the Ottawa County poultry flock.

The facility’s name and ownership were not disclosed by MDARD, but officials noted that this is the second instance of the virus affecting a commercial poultry site in Ottawa County since its initial detection in Michigan in 2022.

Protecting Public Health and Containing the Virus

“Protecting human health and minimizing the spread of HPAI remains a top priority,” said MDARD Director Tim Boring. “Enhancing on-farm biosecurity measures and broadening HPAI surveillance are critical steps to safeguard domestic animals and reduce any potential threat to humans.”

HPAI is a highly contagious virus that spreads rapidly among birds through direct contact, contaminated equipment, wild birds, and even on the clothing of workers.

To contain the outbreak, MDARD placed the affected poultry facility under strict quarantine. Additionally, all birds within the facility will be humanely depopulated to stop further spread of the virus.

Worker Safety and Human Health

Dr. Natasha Bagdasarian, Michigan’s chief medical executive, emphasized the importance of protective measures for farm workers.

“Because this virus can affect both animals and the people who care for them, it’s essential that farm workers continue to use personal protective equipment (PPE). These precautions are crucial to protect individuals, their families, and to prevent potential animal-to-human transmission,” she said.

The Centers for Disease Control and Prevention (CDC) assures the public that the risk of HPAI to human health remains low. No poultry products from infected birds will enter the food supply chain, ensuring food safety for consumers.

Preventive Measures for Poultry Owners

MDARD urges poultry owners to implement biosecurity practices to protect their flocks from HPAI. These steps include:

1. Limit exposure to wild birds: Bring domestic birds indoors or use secure, enclosed outdoor areas.
2. Practice hygiene: Wash hands thoroughly before and after handling birds or moving between coops.
3. Disinfect equipment and clothing: Clean boots, gear, and tools when transitioning between coops. Discard items that cannot be properly disinfected.
4. Avoid sharing equipment: Do not share supplies between farms or coops.
5. Use clean water sources: Provide birds with municipal or well water for drinking.
6. Protect poultry feed: Store feed securely to prevent contact with wild birds or rodents.

Reporting Suspected Cases

Poultry owners who suspect HPAI in their birds should contact MDARD immediately:

• Daytime: 800-292-3939
• After hours: 517-373-0440

For wild bird cases, reports can be submitted through the DNR Eyes in the Field app or by calling the DNR Wildlife Disease Laboratory at 517-336-5030.

By following these protocols, poultry owners and farm workers can help minimize the spread of avian influenza and protect both animal and public health in Michigan.
