"Prions -- the infectious, deformed proteins that cause chronic wasting disease in deer -- can be taken up by plants such as alfalfa, corn and tomatoes, according to new research from the National Wildlife Health Center in Madison."

"The research further demonstrated that stems and leaves from tainted plants were infectious when injected into laboratory mice.

The findings are significant, according to the researchers and other experts, because they reveal a previously unknown potential route of exposure to prions for a Wisconsin deer herd in which the fatal brain illness continues to spread. The disease has also become a pressing issue nationwide: The national Centers for Disease Control and Prevention has identified the deer disease in 17 states and predicts it will spread to other states."
