Just days after the US Food and Drug Administration found traces of the industrial chemical melamine in some samples of infant formula, the agency wants to assure us that the quantity does not pose any threat to our kids.

Dr. Stephen Sundlof, director of the FDA’s Center for Food safety and Applied Nutrition, said “levels of melamine alone or cyanuric acid alone, at or below 1 part per million in infant formula do not raise public health concerns.” Therefore parents should not change anything in their babies’ diet, as this change could leave babies without the necessary nutrients they so much need in this period of their lives.

The announcement comes after the FDA analyzed 74 of the 87 products it has collected since September, when the Chinese scandal around melamine in baby formula started. None of the samples contained both melamine and a related compound, cyanuric acid. After reviewing the samples and animal studies, the agency decided that either melamine or cyanuric acid alone is safe in formula at 1 part per million or less. The results of the other 13 samples are pending.

Melamine killed four babies in China, while around 50,000 other babies became ill after ingesting baby formula. The chemical can lead to the formation of kidney stones and crystals and related complications.

The brands of formula which include traces of melamine are Mead Johnson's Infant Formula Powder, Enfamil LIPIL with Iron; and cyanuric acid was found in Nestle’s Good Start Supreme Infant Formula with Iron. Both were in concentrations some two thousand times smaller than in contaminated Chinese formula and therefore, they are no threat to babies, the FDA says.
