A 4-year-old doe killed on a deer damage shooting permit in Dickinson County's Waucedah Township has tested positive for chronic wasting disease, marking the first confirmation of the incurable deer disease within Michigan's Upper Peninsula.
The finding was verified by Michigan State University's Veterinary Diagnostic Laboratory in East Lansing and the U.S. Department of Agriculture's National Veterinary Services Laboratory in Ames, Iowa.
The deer was shot on an agricultural farm about 4 miles from the Michigan-Wisconsin border.
"We remain committed to maintaining healthy Michigan wildlife for the residents of, and visitors to, this great state, now and into the future," said Michigan Department of Natural Resources Director Keith Creagh. "Fortunately, over the past few years, with the help of hunters, the U.P. CWD Task Force, DNR staffers and others, we are far better prepared to respond to threats posed by chronic wasting disease in the U.P."
Chronic wasting disease is a fatal nervous system disease found in deer, moose and elk. The disease attacks the brain of infected animals, creating small lesions, which result in neurologic symptoms. The disease is always fatal in animals that contract it.
To date, there have been no reported cases of CWD infection in humans.
"We are taking immediate action to address this situation in the Upper Peninsula. In the short term, stepped-up testing and active surveillance is the priority to better understand where the disease exists," said Russ Mason, chief of the DNRs Wildlife Division. "To do this, we need to step up our efforts to collect deer heads for testing in this area. We need to determine if this deer is an individual outlier or whether there are more deer infected in the area."
The DNR has tested hundreds of deer from Upper Peninsula counties bordering Wisconsin. This year alone (as of Oct. 11) a total of 625 deer-damage permit, roadkill and hunter-killed deer have been tested from Dickinson, Gogebic, Menominee and Iron counties.
Chronic wasting disease has been found in free-ranging deer in six additional counties in Michigan - Clinton, Ingham, Ionia, Jackson, Kent and Montcalm. A total of 63 deer within these counties have tested positive for the disease.
The DNR recognizes that deer movements, densities and habitat vary from the U.P. into the Lower Peninsula. DNR officials will review Michigan's CWD Surveillance and Response Plan and the Association of Fish and Wildlife Agencies CWD Best Management Practices in considering additional measures going forward.
"For next hunting season and beyond, the DNR will discuss possible response actions with U.P. hunters and other stakeholders to determine the best approach to fighting CWD in the region," said Chad Stewart, DNR deer management specialist.
A roughly 10-mile core area has been set up, centered on Waucedah Township. Within this area, the DNR has set a goal to test a minimum of 600 deer to better determine the extent of possibly infected deer.
"We need hunters to help us reach this goal, by voluntarily submitting entire deer heads for testing. Hunters can keep the venison," Mason said. At this point, we are not establishing a mandatory deer check in the area, but that may become necessary, if we don't reach our goal.
Several actions will be taken by the DNR including:
- Providing additional drop boxes for deer heads within the area, especially in convenient, high-traffic places.
- Offering disease control permits to interested landowners who have more than 5-acres of land and are within 5-miles of the center of the surveillance area.
- Allowing baiting for deer to continue for the rest of this year. Future decisions on feeding deer will be based on the results of the surveillance efforts.
- An ongoing DNR U.P. deer migration study will be adjusted to include the affected area within its boundaries. Deer will be collared in the area to better understand the movements of deer.
In North America, a total of 25 states and three Canadian provinces have confirmed the presence of chronic wasting disease in free-ranging or captive deer, elk or moose, or both.
