Highly Pathogenic Avian Influenza Detected in a Kent County Commercial Flock

By Jennifer Holton

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 commercial poultry flock from Kent County. This is the second detection of HPAI in Kent County since the virus was first detected in the state in 2022. MDARD continues to strongly recommend owners remain vigilant and actively protect their animals from HPAI, especially as the wild birds carrying this virus complete their spring migration.

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.

According to the U.S. Centers for Disease Control and Prevention, the public health risk associated with avian influenza remains low. 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 protecting 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.
