Wisconsin · Disease surveillance
CWD and EHD in Wisconsin.
Wisconsin confirmed its first wild CWD detection in 2002 in Dane County, becoming one of the first eastern states with established CWD. WI DNR runs free CWD testing and one of the country's most extensive surveillance programs. Most positive counties are in southern Wisconsin.

Carcass transport rules
If hunting in a CWD-positive area, follow your state agency's carcass transport rules — most agencies prohibit moving whole carcasses with brain or spinal tissue across designated zone boundaries. Verify the current rules with your state wildlife agency before transporting any harvest.
Testing
Most state wildlife agencies offer free or low-cost CWD testing of harvested deer at check stations or sample-drop locations during season. Contact the state agency for current testing locations and turnaround times.
