The Wisconsin Department of Natural Resources said a deer in Waukesha County has tested positive for chronic wasting disease.

The agency said it's the first deer in the southeastern Wisconsin county to test positive for the mad-cow-like brain disease.

DNR area wildlife supervisor Tim Lizotte said the finding was not unexpected, since a CWD-positive deer was found 16 miles away in Jefferson County.

Part of Waukesha County is in the existing CWD Management Zone. A landowner in the Town of Delafield reported the sick-looking deer to the DNR.

The sampling result does not change the current management zone boundary. But since Washington County is within 10 miles of where the deer was found, a baiting and feeding ban will go into effect for Washington County before the 2013 deer season.
