Chronic wasting disease test results
CWD testing history
Chronic wasting disease (CWD) was originally detected in Dane County in 2002. An extensive CWD surveillance program has been conducted in Wisconsin since then. Of Wisconsin's 72 counties 18 currently have CWD detected in the wild deer herd. Of the 18 counties 15 are within the area previously known as the CWD Management Zone (CWD-MZ), three counties of which include positives just outside of the border of the former zone (Grant, Waukesha and Juneau). Three counties with positives are outside of the former zone (Washburn, Portage and Adams).
The recent disease detections in areas such as Adams, Juneau and Portage counties as well as locational data collected within the former CWD-MZ, indicate the disease is spreading. The department welcomes public involvement in new areas of detection via the county based citizen County Deer Advisory Councils (CDAC).
CWD test results can searched for individually or viewed in a summary. To search for an individual result a customer ID or CWD barcode will be needed. Tests results are added as they become available. Negative test results are released within a day after they are received. Positive test results are released as soon as they are confirmed and the hunter has been contacted.

Interactive CWD mapping application
A CWD results mapping application is available for users to explore CWD results in all areas of the state as well as create maps. This application shows harvest locations of all deer tested for CWD including the positive test results.
