U.S. health officials have uncovered trace amounts of the chemical melamine in a sample of infant formula sold in the United States.
FDA spokeswoman Judy Leon said. "There's no basis for concern because we're talking about trace levels that are so low ... that there's absolutely no risk."
Melamine-tainted formula in China has caused thousands of children to fall ill; several have died. The concentrations in China were as much as 2,500 parts per million — about 10,000 times greater than what the FDA found in the U.S.
The FDA and other experts said the melamine contamination in U.S.-made formula had occurred during the manufacturing process, rather than intentionally as was done in Chinese production. The manufacturers insist their products are safe.
On November 28th, the U.S. Food and Drug Administration (FDA) took a new stance, stating it will allow trace amounts of melamine in infant formula. This partly reverses the agency's October assessment that it was safe to consume food and beverages with melamine levels below 2.5 parts per million, with the exception of infant formula. The FDA said at the time that it couldn't determine if there was a safe level of melamine and melamine-related compounds in infant formula.
