Highly Pathogenic Avian Influenza Detected in Wexford County Backyard Flock
April 28, 2022
Michigan bird owners need to take every precaution to keep wild birds away from their flocks
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 non-commercial backyard poultry flock from Wexford County. This most recent finding of HPAI emphasizes the ongoing high risk for the disease in Michigan and underscores the need for bird owners to maintain their vigilance in protecting their flocks.
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 will be depopulated to prevent disease spread.
The flock contained approximately 60 birds of various species.
“Even though temperatures have cooled, wild birds are continuing to migrate and spread the virus. The best strategy we have against HPAI is prevention,” said State Veterinarian Dr. Nora Wineland. “Backyard and commercial flock owners need to do everything they can to keep wild birds and their germs away from domestic flocks. MDARD is continuing to promptly respond to all suspected cases of HPAI to minimize the impact of the disease.”
According to the U.S. Centers for Disease Control and Prevention, these HPAI detections do not present an immediate public health concern. No human cases of these avian influenza viruses have been detected in the United States.
Also, no birds or bird products infected with HPAI will enter the commercial food chain. As a reminder, people are encouraged to use caution when selecting food for themselves and their families as well as 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).
