Bird Flu Detected in Commercial Poultry Facility in Ionia County

The Michigan State University Veterinary Diagnostic Laboratory has detected the presence of highly pathogenic avian influenza (HPAI) in a commercial poultry facility from Ionia County. Since the disease was first detected in Michigan in 2022, this is the fourth detection of HPAI in a commercial facility, and the first detection in Ionia County.

Last week, HPAI was detected in cattle in Montcalm County, Michigan that had been transported from an affected premises in Texas.

As wild birds complete their spring migration, it is crucial for every producer to protect their animals from wild birds and the germs they could be carrying.

“As the weather remains cool and wild birds continue their migration, conditions are ideal for the virus to thrive and spread. While these conditions persist, the need to take preventative measures will be high,” said State Veterinarian Dr. Nora Wineland, DVM, MS, DACVPM. “Keeping HPAI out of Michigan’s domestic animals remains a team effort, and it must be a top priority for all.”

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 poultry, by equipment, and on the clothing and shoes of caretakers. To protect other facilities in Michigan, the premises is currently under quarantine, and the birds will be depopulated to prevent disease spread. These efforts also help to ensure the safety and integrity of the commercial food supply.

“Michigan’s egg farmers are among the most proactive in the country, with their diligence leading to rapid detection of HPAI in this flock,” said Dr. Nancy Barr, executive director of Michigan Allied Poultry Industries. “Strict biosecurity measures are in place to protect flocks from the increased threat of HPAI.”

According to the U.S. Centers for Disease Control and Prevention, the public health risk associated with avian influenza remains low. Also, no animals or products infected with HPAI will enter the commercial food chain. As a reminder, people should properly handle and cook all food.

Whether it’s a few backyard birds or a large commercial flock, following a few key steps is fundamental to protect 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 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.

MDARD is continuing to work diligently with local, state, and federal partners to quickly respond to reports of HPAI to best mitigate the spread of the disease and provide outreach.
