Nov. 26, 2008 -- Tiny "trace" amounts of potentially toxic melamine reportedly detected in U.S.-made infant formula pose little if any risk to kids, experts tell WebMD. Investigative reporters for the Associated Press obtained FDA documents showing the agency has been testing U.S. made baby formula for melamine. According to the AP report, one brand of formula contained very small amounts of melamine. Another brand contained similarly tiny amounts of cyanuric acid, a related chemical. And a third maker of infant formula told the AP that its own tests detected small amounts of melamine in its product.
