I'm another one who is highly cautious about the turnover and hygene but will eat what ever my body is craving. During pregnancy I stick to well known food outlets which adhere to strict standards. I would eat prepacked salad if it had an excellent used by date and was being refridgerated properly (but probably not one with mayo). I eat soft cheese that is packaged, not cut in the deli. If I ate red meat I would also eat the packaged (sealed) slices but not the deli cut ones. And especially be careful at home and at friend's places. You might think you are "safe" not eating a huge list of foods but there is a risk in trying to simplify things for yourself that you will inadvertedly eat something because you stop noticing hazards in preparation and storage.
