Following an investigation by the Michigan Department of Agriculture and Rural Development (MDARD), the Michigan State University Veterinary Diagnostic Laboratory has detected highly pathogenic avian influenza (HPAI) in a commercial poultry facility in Muskegon County. 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.”
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.
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.
- Disinfecting boots and other gear when moving between coops.
- Do not share equipment or other supplies between coops or other farms.
- Cleaning and disinfecting equipment and other supplies between uses. If it cannot be disinfected, discard it.
- Using 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 sick or dead domestic birds to best mitigate the spread of HPAI and provide outreach.
Reporting Possible Cases
For Domestic Birds
Domestic bird owners and caretakers should watch for unusual deaths, a drop in egg production, a significant decrease in water consumption, or an increase in sick birds. If avian influenza is suspected in domestic birds, contact MDARD immediately at 800-292-3939 (daytime) or 517-373-0440 (after-hours).
For Wild Birds
If anyone notices what appears to be unusual or unexplained deaths among wild bird populations, please report these cases to the Michigan Department of Natural Resources (DNR) by:
- Using the DNR’s Eyes in the Field app. Choose the “Diseased Wildlife” option among the selections for “Observation Forms.”
- Calling the DNR Wildlife Disease Laboratory at 517-336-5030.
