Colorado · Disease surveillance
CWD and EHD in Colorado.
Colorado is the historical origin region for CWD in wild cervids — the disease was first identified in captive mule deer in the 1960s and confirmed in wild populations by 1981. CPW manages CWD across most of the state's deer and elk units. Verify current testing requirements per game management unit.

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.
