This is the first detection of HPAI in a commercial poultry operation in Michigan.

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 flocks in Michigan, the premises is currently under quarantine, and the birds have been depopulated to prevent disease spread. These efforts also help to ensure the safety and integrity of the commercial food supply.

“Before Michigan’s first detection of HPAI in backyard poultry in late February, MDARD has been preparing for all types of outbreak scenarios, including within a commercial setting, allowing the department to take swift action in partnership with the producer. The department has already identified a control area and surveillance zone to monitor for and prevent further spread of the virus,” said State Veterinarian Dr. Nora Wineland.

“We will continue to ask every poultry owner, whether a backyard owner or commercial grower, to take preventative actions to help stop the spread of HPAI. It’s a team effort to defend the flocks in Michigan.”

“Michigan’s family poultry farmers take the health of their flocks and neighbor farms seriously,” said Allison Brink, Executive Director of Michigan’s Allied Poultry Industries. “By working together to limit the spread of HPAI, Michigan farmers are ensuring there is no disruption in the local turkey, chicken, or egg supply.”

According to the U.S. Centers for Disease Control and Prevention, the public health risk associated with these avian influenza detections remains low. No birds or bird products infected with HPAI will enter the commercial food chain.

As a reminder, people are encouraged to properly handle and cook all poultry and eggs.
