Your doc should give you a list of things not to eat. Oysters are ok in moderation as long as they are smoked or cooked well. There is a lot of fish you can't eat but as you don;t like fish it shouldn't be a prob. Salmon is ok as long as it's north atlantic salmon. As I live in montreal all our salmon is from the north atlantic so it's fine to eat a couple of times a month. Check the label. Also you can't eat anything with raw eggs- certain salad dressings, egg nog (which sucked for me as I was preggers last x-mas (you might have your baby by then-lol)
certain cheeses you can't eat-brie, feta and others. I remember those 2 cause they are 2 of my faves and I have been craving feta and can't have any!!! Anything that is raw or unpasteurized you can't have. But your doc should give you a list of what not to eat.
Good luck and congrats on your new pregnancy!
