I just read the below article which makes an already well-hidden problem even worse - China's hepatitis epidemic, which according to the 2012 CFTU Annual report, caused 179 foreign teachers to contract the horrible disease last year. As you can see from this article many restaurant chains reuse uneaten rice and vegetables.http://www.echinacities.com/news/Yoshin ... Dinnerware
Even worse, perhaps one out of ten restaurants even know what a sterilizer is and thousand of people have used the spoon or chopsticks that you eat with today. Ditto for the cups and glasses. They just use soapy water to clean them. There was a blog post from a doctor who said you have a 1 in 18 chance of contracting the disease for every ten visits to China restaurants, but the government has now deleted the comment.
So anyone going to China should bring their own eating utensils and collapsible cup.
