Food and Drug Administration officials on Friday set a threshold of 1 part per million of melamine in formula, provided a related chemical isn't present. They insisted the formulas are safe.
The setting of the standard comes days after The Associated Press reported that FDA tests found traces of melamine in the infant formula of one major U.S. manufacturer and cyanuric acid, a chemical relative, in the formula of a second major maker. The contaminated samples, which both measured at levels below the new standard, were analyzed several weeks ago.
The FDA had stated in early October that it was unable to set a safety contamination level for melamine in infant formula.
Dr. Stephen Sundlof, FDA's director of food safety, said Friday the agency was confident in setting the 1 part per million level for either of the chemicals alone. although there has been no new scientific studies since October that would give regulators more safety data. He had no ready explanation for why the level wasn't set earlier. http://abcnews.go.com/Health/wireStory?id=6357398
