Minnesota lawmakers will try to block new captive deer farms from opening in an attempt to stop or slow the spread of chronic wasting disease (CWD) in wild deer.
Both Republicans and Democrats in the House have proposed moratoriums on new whitetail farms, which have been hotbeds for the always-fatal CWD — a neurological disease caused by a disordered protein called a prion.
But it's unclear how much support they will have in the Senate to enact a full-fledged ban, as lawmakers weigh the risk that trophy game farms pose to the state's beloved wild deer, moose and elk herds.
Rep. Rob Ecklund, DFL-International Falls, said he understands the stress that deer farm owners have been under as CWD — and state-imposed regulations to fight it — upend their businesses.
"But our wild whitetail deer could be facing the same thing, and that's what I've been working on — making sure we save that industry," he said.
There are about 150 deer and elk farms in Minnesota, down from 400 in 2005. The animals are commonly bred or genetically modified to produce giant bucks for clients to shoot inside the fenced enclosure of a farm. Some raise the animals commercially for venison and to produce deer attractants for hunters, among other uses.
CWD, first discovered in Minnesota on an elk farm in 2002, has been spreading throughout the state. The prion — a misfolded protein that eventually destroys the animal's brain — spreads from deer to deer both directly, when they touch, and indirectly, when a healthy animal comes across infected soil or food.
The quickest way it travels is when infected deer — or deer carcasses — are driven across the state by game farmers or hunters. Over the last five years CWD has been found in wild deer in Fillmore, Dakota and Polk counties and in seven captive deer farms, according to the Department of Natural Resources (DNR).
