If you are squeamish about food you should not eat out anywhere in the world. Many of the people working in your local restaurants do not care much about your health. Observe a men’s room and see how many wash their hands. Do you think they would start doing it just because they got a job handling food? probably not. At any rate, the health concerns are justified as hygiene in China is virtually unknown. If you are squeamish Chinese restaurants are not the best place to be. I, not being squeamish in the least, enjoy them, like I enjoy Mexico. My only precaustion is that I will only eat food that has just been cooked. Soup from a pot that has been boiling for a long time is a pretty safe bet. But food that has been sitting around for a while is something I will not eat anywhere in the world.
