The article goes on to say that the FDA is not yet finished testing samples.
FDA tests found "very low levels" of the industrial chemical melamine in Nestle's Good Start Supreme with Iron formula, said Stephen Sundlof, director of the FDA's Center for Food Safety and Applied Nutrition.
It also found low levels of cyanuric acid in Mead Johnson's Enfamil Lipil with Iron, Sundlof said. Mead Johnson is a unit of Bristol-Myers Squibb.
Those findings "do not raise public health concerns," Sundlof told a conference call. "The domestic supply of infant formula is safe."
Representatives for Nestle and Bristol-Myers could not immediately be reached for comment.
The FDA earlier this week said it had found one brand of formula containing melamine, a chemical used widely in the production of plastics and fertilizer, but declined to name the company to Reuters.
