What happens when you get a positive result?

If your harvested deer tests positive for CWD you will be notified by email if your email address is included in your GoWild customer account, or by letter if your email address is not provided. The U.S. Centers for Disease Control and Prevention states that to date, there have been no reported cases of CWD infection in people. Nonetheless, as a precaution, the Wisconsin Department of Health Services (DHS) recommends that people only consume venison from healthy-appearing deer with test results indicating that CWD was not detected. This is consistent with recommendations from the Center for Disease Control (CDC) and World Health Organization (WHO). Unwanted deer carcass waste or packaged meat should be disposed of in a landfill that accepts this waste.

A replacement deer harvest authorization will be issued to your GoWild customer account within a day of result notification if the result is received before the 9 day gun deer hunting season. If the result is received after the 9 day, the authorization will be issued in late summer for the following hunting season. The replacement authorizations are not weapon specific but will replace the type that was used for the CWD positive deer.

Clean all equipment used to process the deer with soap and water to remove all organic material and rise with water. Then for non-steel items soak in a 50/50 solution of bleach and water for an hour, and for steel items soak for a minimum of 5 minutes. For additional processing details see the carcass handling page.

Interactive CWD results mapping application

The CWD results mapping application lets users explore statewide CWD results. The application allows you to add a layer of CWD sampled or CWD positive deer by township or section. Results can be viewed for one specific year or a range of years. Results are added to the map as soon as they are made public.
