It would be nice, but most people don't even get their venison tested in the first place. Not unless they live in a state where cwd is super common and mandate testing.

I would be willing to guess most processors who work with deer have unknowingly processed a deer with cwd on a fairly regular basis. Even in states who mandate testing, the testing usually doesn't come back until after you've already done the processing. Some states mandate the processor hold the meat until the testing come back, some don't.

We're just very fortunate that it doesn't seem to fuck up humans to a noticeable degree.
