MADISON, Wis. -- State wildlife officials said a deer with chronic wasting disease has turned up in eastern Dane County.

A bow hunter shot the 2-year-old buck in Deerfield, about a mile from the Dane-Jefferson county line.

Department of Natural Resources officials said they were surprised by the positive test, based on the pattern of CWD positives to date.

Surveillance efforts have shown a scattered pattern in the eastern part of the county, while the western side where the eradication zone is, is more concentrated.

“It reinforces to us that we have to keep looking for the disease, and doing surveillance, and getting cooperation from hunters like this guy to try to better understand the distribution of the disease,” said Alan Crossley CWD project leader.

The DNR is still waiting on the test results of some 1,800 deer sampled this fall and winter.

Agency officials said they will wait for the results before evaluating the CWD surveillance strategy.
