Really? It's one thing to understand that whatever pathogen you were infected with is (also) foodborne. But tracking the infection to something particular which you ate is generally quite hard, and it is even harder to track accidental contamination.

And many people do not understand where actual danger comes from. For example it is a really bad idea to rinse raw chicken meat. Yet this practice is still widespread.
