I can hardly believe it but USA Today reports that Chinese infant formula has been found to be contaminated with melamine, the very same toxic ingredient that caused the pet food recalls of 2007. Melamine-laced pet foods killed cats and dogs. Who knows what it might do in infant formula. Melamine is high in nitrogen. Tests for protein just test for nitrogen and don’t care where it comes from. Melamine, which is cheap, makes pet foods and infant formulas look like they have a lot of protein, which is expensive. That would be bad enough but melamine and one of its by-products, cyanuric acid, form crystals that block kidney function. The fraudulent addition of melamine to pet food is precisely the subject of my book, Pet Food Politics. It’s subtitle is The Chihuahua in the Coal Mine. Now you know why.
