Left overs at home - I was told to heat the crap out of it and you're all good. I often took left overs to work for lunch and was fine.

Also apparently McDonald's ice cream/thick shakes are a no go due to listeria. And I did hear something about BBQ chickens

I basically wouldn't eat anything that wasn't freshly cooked (if eating out - ie nothing from those Chinese places in food courts where food was sitting out). And if I was to reheat it would be piping hot.

Not sure about anything else as staying away from cheese is easy for me (I'm allergic) and I did have the odd ham/cheese/tomato toasted sandwich.

Good luck with the rest of your pregnancy.
