I have a handout from my midwife (in the bounty pack) which lists all the foods to be avoided by pregnant women, and includes 'cold cooked meat' like pre packed ham. Avoiding this isn't mentioned in any of my other books/leaflets etc - is it just an old handout or is ham, cold meat etc best avoided? Also it says no prepaked salads, does that include ready made sandwiches from boots etc? Thanks!
