Federal Lab Confirms CWD in Montcalm County Deer
Michigan Ag Connection - 10/09/2017

The U.S. Department of Agriculture's National Veterinary Services Laboratory in Ames, Iowa, confirmed late last week that a 3.5-year-old female deer taken during Michigan's youth deer hunting season in September has tested positive for chronic wasting disease.

The animal, harvested in Montcalm Township in Montcalm County, is the 10th free-ranging deer in Michigan found to have chronic wasting disease. The youth hunter who harvested the deer opted to take the animal to a Department of Natural Resources deer check station and then submitted the animal for testing -- steps the DNR strongly encourages hunters across the state to take during the 2017 deer hunting seasons.

"Because this family decided to bring their deer to a DNR deer check station, state wildlife managers were able to gain important information about chronic wasting disease in mid-Michigan," said Dr. Kelly Straka, DNR state wildlife veterinarian. "As we move through the archery and firearm seasons, voluntary deer testing will be critical not only within the currently affected areas, but also throughout the south-central Lower Peninsula and the entire state."

CWD is a fatal neurological disease that affects white-tailed deer, mule deer, elk and moose. It is caused by the transmission of infectious, self-multiplying proteins (prions) contained in saliva and other body fluids of infected animals. Susceptible animals can acquire CWD by direct exposure to these fluids, from environments contaminated with these fluids or the carcass of a diseased animal.

Some CWD-infected animals will display abnormal behaviors, progressive weight loss and physical debilitation; however, deer can be infected for many years without showing internal or external symptoms. There is no cure; once a deer is infected with CWD, it will die.

Since May 2015, the DNR has actively conducted surveillance for CWD. To date, more than 14,000 deer have been tested since the first positive case was found, with 10 cases of CWD confirmed in free-ranging white-tailed deer identified in Clinton, Ingham and (now) Montcalm counties.

To date, there is no evidence that CWD presents any known risk to non-cervids, including humans, either through contact with an infected animal or from handling venison. However, as a precaution, the U.S. Centers for Disease Control and the World Health Organization recommend that infected animals not be consumed as food by either humans or domestic animals.

As additional deer have tested positive for CWD within Michigan, the DNR has put specific regulations in place. Currently, there are two CWD Core Areas, which are deer management units (DMUs) 333 and 359. To review regulations related to those areas, visit michigan.gov/cwd.
