Something to think about... Bait sites can harbor infectious CWD Prions in the soil and plants for years.

Animals can be infected by oral ingestion of prion-contaminated plants
Prions are the protein-based infectious agents responsible for prion diseases. Environmental prion contamination has been implicated in disease transmission. Here we analyzed the binding and retention of infectious prion protein (PrPSc) to plants.
Wild type hamsters were efficiently infected by ingestion of prion-contaminated plants. The prion-plant interaction occurs with prions from diverse origins, including chronic wasting disease. Furthermore, leaves contaminated by spraying with a prion-containing preparation retained PrPSc?for several weeks in the living plant. Finally, plants can uptake prions from contaminated soil and transport them to aerial parts of the plant (stem and leaves). These findings demonstrate that plants can efficiently bind infectious prions and act as carriers of infectivity, suggesting a possible role of environmental prion contamination in the horizontal transmission of the disease.
It has been shown that infectious prions bind tightly to soil and remain infectious for years in this material.
The main goal of this study was to evaluate whether plants can bind, retain, uptake and transport prions in an experimental setting. Overall, our findings show that grass plants efficiently interact with prions, suggesting that they may play an important role in natural prion transmission, particularly in wild animals.
