On this forum (pretty much dedicated to discussion and news of H5N1 but many related topics) there has been an ongoing discussion about the China/poison/melamine topic for quite some time. Here is a link to the latest page of the thread:

The Lesson from the Pet Food and Spinach Recalls
There are a lot of knowledgeable people discussing this. You have to tolerate (not on this thread so much) some liberal bias; if you can’t tolerate the occasional leftist opinion don’t go there. There is also a security window thingie that comes up, just click yes and you’re on the site. It’s fine, I’ve been reading the site since its inception.
There is very valuable information about melamine, cyanuric acid (or whatever it is) and so on.
Thanks; that looks like a good site.
As to being able to tolerate some liberal bias, well I did go to school & college in the SF-Bay area, in the 60s...and survived.
