I will be killing a deer or two this week to give to the Missouri Department of Conservation to check for CWD. I am looking for older deer knowing that young deer seldom have the prions. I also want bucks, because research has shown the disease is more prevalent in bucks than does. If the deer test negative, I will give the venison to a needy family. But there is still that grain of doubt as to whether or not the testing is always perfect and accurate.
