MDARD Urges All Michiganders to Help Protect Against Highly Pathogenic Avian Influenza this Fall

Precautions are needed as wild birds continue to spread HPAI during their fall migration

LANSING, MI – With a second detection of highly pathogenic avian influenza (HPAI) in a 

domestic flock during the fall migration season for wild birds, the Michigan Department of 
Agriculture and Rural Development (MDARD) is urging Michiganders to avoid feeding wild 
waterfowl, continue to suspend their use of backyard bird feeders, and take other precautions to 
limit the spread of the virus.

Following an investigation by MDARD, the Michigan State University Veterinary Diagnostic 
Laboratory detected the presence of HPAI in a non-commercial backyard poultry flock from 
Macomb County. This case marks the third detection of HPAI in Macomb County this year. The 
premises is currently under quarantine to protect other flocks in Michigan, and the birds were 
depopulated to prevent disease spread. The flock contained approximately 40 birds of various 

“This newest detection is not unexpected as the virus is known to be carried by wild birds. 
However, this case does highlight the need for everyone to take steps to avoid attracting wild 
birds to their property—especially if they have a poultry flock,” said State Veterinarian Dr. Nora 
. “Keeping domestic birds away from natural bodies of water, not feeding them next to 
wild birds, and preventing them from interacting with wild birds are all essential practices to 
ensure domestic birds can stay healthy and safe.”

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.

According to the U.S. Centers for Disease Control and Prevention, the public health risk associated with this avian influenza detection remains low. Also, no birds or bird products infected with HPAI will enter the commercial food chain. As a reminder, people should 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 multiple sudden deaths in the flock, 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).
