I never thought about health concerns. I certainly could be wrong (since I"ve never checked into it) but I assumed all grocery stores in the US had to adhere to certain standards. However, I've been buying food from Asian groceries for 20+ years and never had any issues.
The only really gross thing I had happen at a grocery store was at a well-known American chain grocery store, and it was a one-time thing. (a fly was in my steak! Ewwwwww! Inside the shrink wrap! Yes, they apologized like mad dogs.)
Anyway, I like Chinese and Thai foods, and I like sushi too, and it's easier and cheaper to buy some of the ingredients at Asian stores. I buy sushi rice, sauces, such as hosin sauce, fish sauce, rice vinegar; bamboo sprouts, tofu, the tiny little pieces of corn, shiitake mushrooms, and nuts. They have great prices on cashews!
As for the language barrier, I've never had a problem handing the clerk my money and getting back the correct change. I don't even recall noticing whether they spoke to me in English or not. Some of the products are a mystery to figure out, but most of them are either labeled in Chinese and English, or it's pretty obvious what it is without reading the label.
Try it out - it's fun to experiment with new ingredients!
