I know in my last post I stated that in order to get sick from food within a few hours that it would have to be so rancid that you wouldn't want to put it in your mouth........there are however several bacterial infections that are tastless, and oderless. SO don't let the nose always be your guide. If you saw a food service worker with an open wound.......I'd only use my nose to guide me to a new place to eat lol.
