Highly Pathogenic Avian Influenza Detected in Oakland County Flock

Using personal protective equipment and other biosecurity protocols remain essential to protecting both animal and public health

LANSING, MI - Following an investigation by the Michigan Department of Agriculture and Rural Development (MDARD), the Michigan State University Veterinary Diagnostic Laboratory has detected the presence of highly pathogenic avian influenza (HPAI) in a backyard flock from Oakland County. This is the second case of HPAI in Oakland County since the virus was first detected in Michigan in 2022. Adhering to biosecurity measures and using personal protective equipment (PPE) continue to be vital in helping ensure the health of Michigan's domestic animals and the general public.

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 animals, by equipment, and on the clothing and shoes of caretakers. The affected premises is currently under quarantine, and the birds will be depopulated to prevent disease spread.

According to the U.S. Centers for Disease Control and Prevention, the public health risk associated with avian influenza 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.
• 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 uses. 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 sick domestic animals 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, diarrhea, sneezing/coughing, or an increase in sick birds.
