How do you lose 800 metric tons of wheat gluten? ChemNutra says it imported the stuff from Xuzhou Anying Biologic Technology Development, then shipped it to Menu Foods and other companies. Both the Chinese government and Xuzhou claim that the company has never exported wheat gluten to the US or Canada.
All of this matters, of course, because the wheat gluten turned out to be contaminated, leading to a massive pet food recall, lots of sick pets, lots of unhappy owners, and inevitable lawsuits. The earliest known source of the stuff -- ChemNutra, at the moment -- is in a world of trouble with their customers.
