Lyndsey Layton reports in the Washington Post:
The FDA has been testing hundreds of food products for melamine in the aftermath of a scandal this year involving Chinese infant formula tainted with melamine. Chinese manufacturers deliberately added the chemical to watered-down formula to make it appear to contain higher levels of protein. More than 50,000 Asian infants were hospitalized, and at least four died.
The FDA collected 87 samples of infant formula made by American manufacturers, tested all but 10 of them and held a conference call Monday with manufacturers to alert them to the preliminary findings, FDA spokeswoman Judy Leon said. She said she did not know when the agency was planning to inform the public.
