Also things like nuts and shellfish (cooked of course) should only need to be avoided if you have a family history of an allergy. I've eaten all sorts of nuts throughout my pregnancy. JUst check things to make sure they are pasturised. My friend made her life very difficult by being really picky and not eating salads or reheated meals because it was in her pregnancy book about making sure they are washed/reheated properly. Now I am very careful anyway (having had Salmonella) and have eated Salad and I've cooked extra portions of meals I can eat for lunch the next day and I have been fine. Try not to worry, just be sensible and avoid the things mentioned in other posts like soft cheese, runny eggs and undercooked meat.
