PIERRE, S.D. (KCCR) – Chronic wasting disease, which impacts deer, moose and elk has been found in four new central South Dakota counties in the last month. Those counties include Sully, Lyman, Ziebach and last Friday Mellette. Wildlife Program Administrator Chad Switzer with the South Dakota Game Fish and Parks Department says the movement east is of interest to them.

Switzer says the Game, Fish and Parks Department is getting good participation from hunters with surveillance for Chronic Wasting Disease.

Switzer says while Chronic Wasting Disease is worth watching other diseases that afflict big game are of more concern, especially to hunters.

Sully, Lyman and Mellette Counties are the farthest east C-W-D has been found and Sully County means the disease has crossed into East River South Dakota.
