If it wasn’t confusing enough, three more toxins were found in the urine and kidneys of sick pets.
Researchers in at least three labs found cyanuric acid, amilorine and amiloride — all by-products of melamine — in the crystals of animals’ urine, tissues and kidneys…
Finding cyanuric acid is the more significant finding, Hoff, Goldstein and Mullaney said, although they are not yet certain how toxic it is to animals.
The Centers for Disease Control and Prevention’s Web site said, “When ingested (by humans) in large amounts, the substance may have effects on the kidneys, resulting in tissue lesions.”
Also, pigs that ate contaminated rice protein were slaughtered and sold before the government could quarantine them. It is not clear whether the meat made it into consumers’ hands. The pigs ate salvaged pet food from Diamond Pet Foods.
Researchers also ruled out aminopterin, previously announced by NY state. No explanation is given as to how this decision was made.
