I put very little stock into the whole pregnancy no-nos, at least as far as food goes. I eat the same way when pregnant as when I'm not. I agree it's a moderation in all things issue. I don't normally eat a lot of raw fish at sushi anyway, and I never drink alcohol, so my diet really doesn't change. I think even unpasteurized dairy, if it came from a source you know and trust, would be just as safe as anything coming out of a factory. When you look at the big food scares in the past few years, it's all sourced to factories (peanut butter, eggs, tomatoes, bagged spinach...). I don't eat all farm raised food or something-- not at all. But I'm just saying anything we eat can have huge risks, and you can't make yourself paranoid because you need food. So I'd say go for it and just heat it up if you feel concerned. But I take a very relaxed view of this stuff, so do what makes you comfortable.
