Shelisa, actally contrary to your dr being 'ang moh', all the ang mo foods say avoid raw foods (sashimi, sushi, raw yolks, etc.). BUT both my sister and my gynae said go ahead, as long as they're from reputable eating places. I never cut sashimi out from my diet. In fact, I had a sashimi buffet the very same day I tested positive and still have it every now and then.
Gynae said if in other countries, then avoid buying these things from roadside stalls or hawkers. Ditto with raw eye yolks. I LOVE THEM and have been enjoying them with my ban mian or ya kun toast. =) Again, our gynae's both affirmed that Sg eggs generally ok unless you've got your own chicken, I guess.
