Tamesbm,
China is a huge country and by far the most populated one. So if the crime rate there is the same as that of your country, it could be a few times more noticeable.
In terms of tea production practices, I have seen the best and the worst in there. From advanced machines with modern management, the strictest practice of organic productions, tiny tea farms run by families with very traditional practices, and irresponsible enterprises interested only in margin and turnover. They are all there.
I have no reliable data (official says it’s almost 99%) as to how much of the country’s throughput conforms to United Nations food safety standards. However, all normal exports should conform to the food safety regulations set by the importing country. If the customs office in your country is doing their job, the tea you are getting should be as safe as any other grocery items.
