Public health groups, consumer advocates and members of Congress blasted the Food and Drug Administration yesterday for failing to act after discovering trace amounts of the industrial chemical melamine in baby formula sold in the United States. This FDA, this Bush administration, instead of protecting the public health, is protecting industry," said Rep. Rosa DeLauro (D-Conn.), who chairs the Appropriations subcommittee that oversees the FDA budget. "We're talking about babies, about the most vulnerable. This really makes me angry." 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. The FDA has been testing hundreds of food products for melamine in the aftermath of a scandal this year involving Chinese infant formula tainted with melamine. Chinese manufacturers deliberately added the chemical to watered-down formula to make it appear to contain higher levels of protein. More than 50,000 Asian infants were hospitalized, and at least four died.
