Two months after vast quantities of milk from China were found to contain melamine, sickening 53,000 children and sending 13,000 to hospital, the FDA announced all Chinese milk imports will be stopped at the border until they’re proven melamin-free.. While it’s taken them a while to do this, banning entire categories of products from specific countries is a rare move, and it will have long-lasting impact. “It’s impossible to get off the alert list,” said Benjamin England, a former FDA lawyer. Unscrupulous food makers adulterate products with melamine because they fool testing equipment to make the product look high in protein. In spring ’07, about two dozen pets died after eating pet food tainted with melamine.
