Michigan deer face potential deadly threat of chronic wasting disease

A serious health threat to state’s wild deer population has been detected in mid-Michigan. 

A six-year-old doe found in Haslett last month has tested positive for chronic wasting disease. 

The neurological disease is always fatal.  The disease is transmitted through saliva and other bodily fluids.   The disease is fatal to deer, elk and moose. 

Chronic wasting disease first was identified in 1967 as a clinical disease in captive mule deer at the Colorado Division of Wildlife Foothills Wildlife Research Facility in Fort Collins, Colorado. Since then, most CWD cases have occurred in western states, but in the past 15 years it has spread to some Midwestern and eastern states.

In all, CWD has been detected in 23 states and two Canadian provinces. 

There was a case in Michigan in 2008.  A white-tailed deer from a privately owned facility in Kent County tested positive for CWD. 

This is the first case involving a free-ranging white tail deer. 

State wildlife officials admit they don’t know where the deer in Meridian Township may have contracted the disease. Genetic testing suggests the deer is from the local area. 

And it may not be alone.

“Nobody can say there aren’t others out there,” says Steve Schmitt, veterinarian-in-charge at the DNR Wildlife Disease Lab. “I would expect that this is not the only CWD-positive deer.”

If CWD is not contained, it could have a serious effect on Michigan’s deer, elk, and moose populations.

“Our hope and thought at this time is we only have one confirmed deer … is that this will not be going statewide,” says James Averill, the state veterinarian.  

State wildlife officials are launching several efforts to contain the potential spread of CWD. During the next three years, the Department of Natural Resources will encourage hunters to kill more deer in parts of Ingham, Clinton, and Shiawassee Counties. The DNR is also stepping up its testing of deer from the affected areas.

“Today’s announcement … is nothing short of tragic and today is a day many of us hoped would never come, though it is not wholly unexpected,” said Dan Eichinger, executive director of Michigan United Conservation Clubs.  

The major hunting lobbying group is urging Michigan hunters to work with state wildlife officials to control and hopefully eradicate CWD in Michigan.  

Anyone observing unusually thin or deer behaving strangely to call the DNR Wildlife Disease Lab at 517-336-5030. There is also a way to file a report with the DNR online.
