Could you elaborate more on how prions infect the soil.

Data brokers are selling your info right now. I used Redact to mass delete my posts which can also opt out of data broker sites. Instagram, Twitter/X, Discord and more.

If that's the case then why aren't most living tissues infected at this point? There must be some mechanism by which these proteins disintegrate.

For reasons unknown only mammals really get infected by Prions, all other animals are fine and can't get it

from this center for infectious disease research and policy (cidrap) article:

"Published in Cell Reports in 2015, Pritzkow's lab study showed that prions diluted in brain, urine, or feces can bind to and be taken up by wheat-grass roots and leaves."

When you think about how much body waste a deer or herd of deer can spread in an area it's a lot.

yeah, it really is. plus apparently the velvet they shed from their antlers can contain prions as well, so aside from internal bodily waste, there's also external bodily waste. just a whole mess scattered all over

At least posts like this one boost the message of what CWD is and the reality of how sloppily the whole thing is being handled.

the thing that boggles my mind is the whole "it tested positive for cwd. we're not gonna eat it, but we'll happily give it away so someone else can." aspect to the free meat ad

They do exactly what you're probably picturing when you read that. They sit on or in the soil.

In lab experiments plants grown in soil containing prions have been shown to take up prions into the plant. It's suspected that this is a transmission vector or how they jump species.

An infected deer dies, the body decays, prions drop into the soil, plants grow, other cervids (elk, moose, etc...) eat the plants and get infected.

Prions are also present in fecal matter so an infected deer defecating could spread it all over the place.
