The FDA found melamine and cyanuric acid, a related chemical, in samples of baby formula made by major U.S. manufacturers. Melamine can cause kidney and bladder stones and, in worst cases, kidney failure and death. If melamine and cyanuric acid combine, they can form round yellow crystals that can also damage kidneys and destroy renal function.
Melamine was found in Good Start Supreme Infant Formula With Iron made by Nestle, and cyanuric acid was detected in Enfamil Lipil With Iron infant formula powder made by Mead Johnson.
Findings by Nestle related to their dairy herds in South Africa, shows that melamine crosses the feed/food barrier, as melamine laced corn gluten fed to dairy cows showed up in infant formula made with the milk.
