Tiny bit of melamine in food is OK, experts say/ But U.S. officials emphasize they won't tolerate deliberate additions

...officials stressed the scientific assessment does not mean that U.S. authorities will tolerate any melamine that is deliberately added to foods. In China, unscrupulous suppliers appear to have been adding melamine to make watered-down milk seem protein-rich in quality-control tests. That's because melamine is high in nitrogen, as is protein.

"If products are adulterated because they contain melamine, (authorities) will take appropriate actions to prevent the products from entering commerce," the FDA said in a statement. The agency said it was setting the 2.5 parts-per-million standard to address situations in which the chemical accidentally comes into contact with food, such as in cases where it is used for industrial purposes in a factory that makes food products.

Officials also stressed that infant formula sold to U.S. consumers must be completely free of melamine.

"There is too much uncertainty to set a level in infant formula and rule out any public health concern," the FDA said.
