Kristie - i wouldn't worry about it! i eat sushi nearly every day for lunch and my doctor says it's perfectly fine. i do make sure i go to shops with a high turn-over to increase the likelihood that it's been freshly prepared, but as my OB says - pregnant women in Japan eat sushi all the time without any problems!!

CelticMoon - i wish i was as good as you - making your own sushi at home - how organised!! i'm WAY too lazy to do that! (plus my own sushi never tastes as good as the shops!)
