First Cases of CWD in Missouri

The first cases of CWD in Missouri were detected in 2010 and 2011 in captive deer at private big-game breeding and hunting facilities in Linn and Macon counties. A total of 11 cases were confirmed in captive deer at the facilities.

What MDC is doing to Slow the Spread of CWD

  • MDC works with hunters, landowners, taxidermists, meat processors and others through mandatory, voluntary, and post-season sampling to collect tissue samples for CWD testing.
  • MDC has removed the antler-point restriction for counties in the CWD Management Zone because young bucks can spread the disease to new areas as they search for territory and mates.
  • MDC allows the use of two firearms antlerless permits in counties in the CWD Management Zone to help prevent undesired population increases in local deer numbers.
  • MDC has restricted feeding deer and placing minerals for deer in counties of the CWD Management Zone.
  • MDC strongly discourages the removal of deer carcasses from counties in the CWD Management Zone.
  • MDC encourages people to report sick deer to local staff.

What People Can Do To Help

  • Have harvested deer tested for CWD through mandatory or voluntary sampling opportunities.
  • Do not move deer carcasses out of the CWD Management Zone.
  • Do not feed deer or place minerals for deer.
  • Report deer that look sick or are acting strange to MDC conservation agents or regional offices.
