Some of us are aware of this.

I have a strong hunch that some things are being taken out of context. When the Chinese say they've been adding melamine for a long time, I don't doubt it. But [unless I'm totally out of bed here] they've been selling this as livestock feed and feed additives. That translates to ruminants, who can easily digest this stuff with no problem at all. It's only been more recently that they've been adding more melamine to the recipe and selling it to pet food manufacturers.

Again, I could be the one who's misunderstanding, though I tend to suspect there's a real messy paperwork trail in terms of purchase orders and resales. I even wonder if American buyers truly understand the difference between an animal with one stomach versus an animal with 4. And do they know exactly what the potential of serious injury is to the animal if given the wrong food?

I also have a hunch that with the unskilled Chinese workers and unregulated quality that precise measurement of NPN's was not a critical issue, as it should have been. Which would explain why some bags in a lot had higher melamine concentrations than others.

If only someone would go underground........in China.......and as an purchasing agent in the US. Oh, the stories I'll bet they could tell.
