I just wanted to say that everyone here is so educated. Sometimes you'll read a message board and the advice is just absurd!!
The posts here are right on the money!
I have gotten true food poisoning twice. Once it was at Applebees from a dessert - I was told it was likely staph and I won't go into that, but it was miserable.
The second time DH and I shared a Cobb salad in chicago at some restaurant in the mall (sustainable agriculture type place) and uuuugh - we were soooooo sick the next day. (That was the only thing that we both ate so we knew it was the culprit). It took a bit longer for me to get sick, since I only had a small amount, and he was sick FAR worse than I was. Pretty cut and dry.
So, now, when eating out I avoid the following:
no lunch meats, unless heated to steaming (listeria) same for hotdogs (we don't really eat either of those anyway, but just FYI)
never eat ground beef - uuugh.
Raw/undercooked food - eggs in particular! These are major culprits (scrambled that are undercooked or raw yolks). I always get egg beaters, which are pasteurized.
When I get a filet at Les Cellier, for example, I ask for it well done and butterflied - this opens it up all the way and makes sure it is cooked thoroughly (now, realistically, it is only when you poke through undercooked meat that you introduce bacteria - because it is a muscle, it is sterile) But, that's another Alton episode
I avoid real caesar salad dressing, for sure - and raw oysters, etc. Also, when I got sick at applebees the health department said that the main carriers of staph are in dairy items that are kept at room temperature - like creamy salad dressings that aren't cold, custards, etc.
However, I can attest to the fact that the maple creme brulee at Les Cellier was WOOONDERFUL and came perfectly chilled with a warm, crackly crust.
Oh - and I never eat salads out of my house anymore. It's WAY too easy for someone to be dealing with raw meats and then step over to make the salad. (which is what I'm sure happened with our salad). Plus, if the lettuce isn't washed properly it can harbor e-coli, and that's a whole other brain-liquifying disease you don't even want to go near!
But, good hygiene - making sure you wash your hands after you sit down for your meal and before you eat, avoiding their disgusting water like the plague (and no, brita bottles do not remove the things IN the water),
