What I was told during anitnatel classes was its fine to eat things you have preared at home, but shouldn't be eaten after 24 hrs (even when stored correctly in the fridge). This is due to the bacteria that grows and normally wouldn't be of any harm to us, but can be dangerous to bubby.

As for cheese, they say you should steer clear of soft cheese. So your regular chedder and tastey cheeses, etc are fine. Once again this is due to the bacteria content.

Its a little confusing to start with in regards to all things you shouldn't be eating during pregnancy!
