The Wisconsin Department of Natural Resources reports a wild deer in northwestern Wisconsin has tested positive for chronic wasting disease. That deer was found just outside Shell Lake last November. Test results from a laboratory in Ames, Iowa, confirmed the deer was infected. The fatal brain disease was first discovered in Wisconsin near Mount Horeb 10 years ago. The DNR thought it had managed to contain it to a zone around that south-central community by adopting a controversial policy which allowed hunters to kill as many deer as possible there.
