Technically, it’s never been proven that deer can contract CWD from the ingestion of plants. Although, apparently mice and hamsters can.
But, prions suck. Even bleach won’t kill these bastards.
Hell, although there’s no real, strong evidence to suggest it actually has made the jump, and research has shown it would be really difficult, its probably not impossible. If you ENTERTAIN the stories about the people suspected of possibly contracting CWD, it’s even more scary. (Yes, I know the study does more to disprove human infection, than not, but it does a good job of outline suspected cases)
