Alarming Rise in Waterfowl Deaths Across Lower Michigan Linked to Suspected Avian Influenza OutbreakSource: Facebook/Michigan Department of Natural Resources

Michigan wildlife authorities report over 300 dead wild birds across Lower Michigan, with highly pathogenic avian influenza suspected. According to the Michigan Department of Natural Resources, the virus is spreading, with recent cases in five counties. Allegan County’s Allegan State Game Area recorded 77 dead Canada geese and one mallard, while over 80 geese were found in Shiawassee County’s Shiawassee River. Ingham County near Williamston Lakes reported about 25 dead geese, Eaton County’s Grand Ledge along the Grand River had 20, and Washtenaw County recorded around 100 dead birds.

Preliminary testing at the Michigan State University Veterinary Diagnostics Laboratory indicates the presence of avian influenza, with samples sent to the U.S. Department of Agriculture’s National Veterinary Services Laboratory for confirmation, which may take weeks or months. "Confirmed positive cases are posted on the DNR HPAI webpage. However, HPAI is widespread in wild birds throughout Michigan." The Michigan Department of Natural Resources advises that the virus may be present even in counties without confirmed cases. To reduce risk, DNR Wildlife Health Supervisor Mitch Marcus stated, "If you find a dead wild bird, you should leave it alone; however, if you need to remove it, do not touch it with your bare hands. You should wear gloves and other personal protective equipment."

The Michigan Department of Natural Resources is monitoring highly pathogenic avian influenza in wildlife. While the disease is present, officials do not expect major impacts on the state's overall waterfowl populations. However, "the populations immediately near the sites with positive test results could see a decline, but there should not be impacts to the statewide population." The Michigan Department of Natural Resources advises the public to avoid close contact with wildlife and keep domestic animals away from potentially infected animals. The Michigan Department of Agriculture and Rural Development provides biosecurity guidance for flock and herd owners, while the Michigan Department of Health and Human Services offers public health recommendations. The risk to human health is considered low, but precautions are advised for those in contact with infected animals or environments.
