icravecheese - totally right. I'm pregnant and living in France at the moment. I was given a (long) list of foods I cannot eat. There is a lot more of what we can't eat over here than in the UK because there is a fair amount of food/cuisine that uses unpasturised milk, uncooked egg whites, uncooked meats etc as well as the French determination to never cook meat to 'well done'.
At the beginning of the pregnancy I got tested for toxoplasmosis. As I tested negative, I have monthly blood tests for it. One month, because I had an upset stomach, I had to have two blood tests...!
Salad out of the home, where the level of washing cannot be verified, is totally out too, as are preprepared sandwiches and anything else in delis... It's not that French woman are strict with themselves, they are strongly advised not to eat (a lot) of foods.
My MIL (French) will not serve me salad. She makes salad for the whole family and will make boiled veggies for me, because she wants to make sure that I'm eating 'properly' and won't get ill. She did, however, tell me, "Don't worry about alcohol. A little bit now and again won't do any harm." She's tea-total!
Back to the brie, and as long as it says that it is pasturised, it should be ok. That is the 'rule' over here.
