Notice: Hunters who harvest a deer from a CWD Management Zone county on Nov. 14th & 15th will not be required this year to bring their deer to an MDC sampling station on the day of harvest due to Public Health concerns tied to the ongoing COVID-19 Pandemic. However, 71 sampling stations in these counties will remain open and hunters are encouraged to voluntarily participate in CWD sampling on those days.

Hunters who harvest a deer in a CWD Management Zone county should be aware of new carcass transport regulations.

Chronic Wasting Disease (CWD) is a deadly illness in white-tailed deer and other members of the deer family, called cervids.

The disease has been found in Missouri and is slowly spreading. The Missouri Department of Conservation is working with conservation partners to find cases and limit its spread. CWD remains relatively rare in the state at this time.
