I go back and forth on federal or state regulation, much less global regulation, but this furtherance of the melamine scenario is very very disheartening.

As I understand it, it does almost no good to not buy stuff with china on the label, as the products are very well distributed to other countries which could be named as sources.
I'd say that cheating seems to be the way there, except .... I'm aware of the western world history.
