Why would I want to be careful? You shot off your own toes with your own post" The origin of CWD is unknown, and it may never be possible to definitively determine how or when CWD arose." Many people know the disease started west of the Mississippi, had been there for years and recently and by recently I don;t mean last year, it appeared on the east side of the Mississippi. It is also known it is in the same family as scrapie and Mad cow disease. So I don't have to be care, I posted most of this a while back. It is likely the disease was carried across the Mississippi by someone bringing new stock to a deer farm but no one knows. However your pronounce that the government brought it east of the Mississippi and I assume from you post by bringing elk east to start a herd is the culprit is pure speculation as are all the other posibilities. As far as interstate transportation now that we know about CWD and the inability to destroy it and its longevity living in the soil and plant roots,it is flat out stupid for anyone to do so, including state agencies. The big thing no one wants to talk about is the proclivity of prions to jump species barriers and affect other species that it in the past did not affect. That would include humans as Mad cow affects humans and there is no cure except death. If mad cow jumps the species barrier to affect humans and perhaps domestic cattle, deer hunting will be a thing of the past in any state where CWD pops up. You may want to promote a caviler approach to CWD but prion diseases are little understood by science so caution is the prudent tack to take.
