The Food and Drug Administration (FDA) confirmed the presence of 'trace amounts' of melamine in a US-manufactured infant formula. The toxic chemical has sickened tens of thousands of infants in China, and killed four - the faked formula having large amounts of melamine added to watered-down milk, to make it appear to have appropriate protein content.
The trace amounts of melamine and its by-product, cyanuric acid, were found in formula from Abbott Laboratories, Nestle and Mead Johnson, which together make more than 90% of all infant formula produced in the United States.
