Traces of the toxic chemical melamine have been discovered in samples of U.S. baby formula, the Food and Drug Administration has admitted.
However, in an interview with the Associated Press, the FDA said that the low levels detected are considered by the department to be "perfectly fine" and not dangerous to public health.
In China, melamine has been linked to the death of at least three babies, as well as the illness of tens of thousands of other children. The FDA previously said that it would not set a limit on "acceptable" levels of the chemical in U.S. formula.
Documents obtained by the AP reveal that out of 77 samples of infant formula, one product contained trace amounts of the chemical. Additionally, cyanuric acid – a byproduct of melamine – was discovered in a different product.
The FDA said that the melamine had likely contaminated the formula during the manufacturing process and had not been added deliberately. Trace amounts are defined as under 250 parts per billion.
"There’s no cause for concern or no risk from these levels," agency spokesperson Judy Leon told the New York Times.
