...or any other foodstuff not gathered from the wild.
Nothing wrong with trying to eat pre-agricultural foods :) It saved my life and got me back to work.
I like to know what is in my food, and I understand the farmers who saw crop damage because some other farmer exposed them to risk without their consent. At the same time, I realize how impossible it is to track every detail of contamination and cross-over in agriculture, so I don't really think these types of lawsuits will be very useful.
