I ate out last week and had a horrible gastro-intestinal problem that lasted two days. I'm thinking it was either from the Mexican restaurant that previous Sunday or from the McDonalds' fish burger that Monday. It got me good. During it, I swore I would not eat out anymore, but I've already broken that pledge.
Yeah, try not to eat out. If you are really busy, try doing crockpot foods.
Whenever you eat out you're taking your life in your hands. One horrible bout with food poisoning was enough for this infidel. Found this, 
practically a miracle cure for food poisoning and other things too. Will never eat out without it as a backup now.
