I think the most important part of keeping the food supply healthy isn't the compost (where we will have to agree to disagree - e coli, etc aren't going to "survive" after 2 or 3 years in the compost, they just aren't) - it's to wash the produce that has been handled in the grocery store. By multiple people, from the produce clerk to random customers to the checkout clerk and the bagging person, if there is one. I often give produce a quick swish through the dishwater and rinse it well.
