DNR announces expansion of Chronic Wasting Disease Core Area and Management Zone

Additional townships and counties are affected

The Michigan Natural Resources Commission expanded the Core Chronic Wasting Disease (CWD) Area to include 17 townships. This area, which will continue to be referred to as Deer Management Unit (DMU) 333, now will consist of Lansing, Meridian, Williamstown, Delhi, Alaiedon and Wheatfield townships in Ingham County; DeWitt, Bath, Watertown, Eagle, Westphalia, Riley, Olive and Victor townships in Clinton County; Woodhull Township in Shiawassee County, and Oneida and Delta townships in Eaton County.

The CWD Management Zone also has expanded; it now will include the remainder of Clinton, Eaton, Ingham and Shiawassee counties, as well as all of Ionia County. The expanded Management Zone will be referred to as DMU 419.

“With the detection of CWD-positive deer in the southern part of Clinton County, we need to better understand the magnitude of the disease in those areas,” said Chad Stewart, Department of Natural Resources deer specialist. “Expanding our surveillance to include those areas is key at this point, and we need help from landowners and hunters within the expanded zone to help us with this effort.”

Other regulation changes include:

  • Banning deer feeding and baiting on all properties within the Core CWD Area and Management Zone.

  • Opening Eaton and Ionia counties to the early antlerless deer season.

  • Allowing roadkill deer in the Core CWD Area to be possessed and kept with a DNR-issued salvage tag from a law enforcement officer or DNR employee, as long as the head is submitted to a DNR biologist, biologist appointee or check station. http://www.michigan.gov/documents/dnr/deercheck_439367_7.html

Continuing from last year, other regulation reminders include:

  • Those hunting within the Core CWD Area are required to present the head of all hunter-harvested deer within 72 hours of harvest to a DNR deer check station.

  • Hunters leaving the Core CWD Area are required to present the entire carcass of all hunter-harvested deer originating from the Core CWD Area within 72 hours of harvest to a DNR deer check station. (A list of deer check stations is available at michigan.gov/deercheck.)

  • All live free-ranging deer from within the CWD Management Zone or Core CWD Area are prohibited from being rehabilitated. Permittees located within the CWD Management Zone or Core CWD Area may no longer rehabilitate deer.

CWD affects members of the deer family, including 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. Since the May 2015 discovery of chronic wasting disease in a free-ranging, Michigan white-tailed deer, more than 5,000 deer have been tested for CWD in order to gauge the extent of the disease across the landscape. Of those tested, seven deer were confirmed positive for the disease in Clinton and Ingham counties.

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

In an effort to end common CWD misconceptions, the DNR in mid-July will launch a 10-week CWD myth-busting campaign. Visit mi.gov/cwd for more information at that time.

The Michigan Department of Natural Resources is committed to the conservation, protection, management, use and enjoyment of the state’s natural and cultural resources for current and future generations. For more information, go to www.michigan.gov/dnr.

*** How Did CWD Get Way Down In Medina County, Texas?


DISCUSSION Observations of natural outbreaks of scrapie indicated that the disease spread from flock to flock by the movement of infected, but apparently normal, sheep which were incubating the disease.


There was no evidence that the disease spread to adjacent flocks in the absent of such movements or that vectors or other host species were involved in the spread of scrapie to sheep or goats; however, these possibilities should be kept open...

Scrapie-like disorder in a Nyala (Tragelaphus angasi)







Spongiform encephalopathy has so far only been recorded in the sheep and goat, man, mink, and several deer including the mule deer, black tailed deer and the elk (most, if not all, of the deer incidents occurred in wild life parts in Wyoming and Colorado). Clinical cases in deer all occurred from 3 1/2 to 5 years old and usually 60-80% losses occurred over a 4 year period...



The clinical and neuropathological findings in F22 are consistent with the spongiform encephalopathies of animals and man. The agents causing spongiform encephalopathy in various species cannot be unequivocally distinguished and some isolates of human agent cause neurologic disease in goats indistinguishable from scrapie. The spongiform encephalopathies are invariably fatal once clinical signs of disease are evident and as very high fatality rates (79% of 67 animals) are recorded in Mule deer it is important that an awareness of the disease is maintained at Marwell.



”The occurrence of CWD must be viewed against the contest of the locations in which it occurred. It was an incidental and unwelcome complication of the respective wildlife research programmes. Despite it’s subsequent recognition as a new disease of cervids, therefore justifying direct investigation, no specific research funding was forthcoming. The USDA veiwed it as a wildlife problem and consequently not their province!” page 26.
