Mmm-mmm Melamine, Part II

Via ProMED-mail: the Washington Post reports on more Chinese melamine in the food chain:

At least 2.5 million broiler chickens from an Indiana producer were fed pet food scraps contaminated with the chemical melamine and subsequently sold for human consumption, federal health officials reported yesterday.
Hundreds of other producers may have similarly sold an unknown amount of contaminated poultry in recent months, they added, painting a picture of much broader consumption of contaminated feed and food than had previously been acknowledged in the widening pet food scandal.
[...]
Meanwhile, the FDA expanded the number of plant-based protein products from China on its "do not import" list, pending the completion of further tests on various kinds of glutens, protein concentrates and other products.
At the center of the problem are pet foods spiked with melamine, a mildly toxic chemical that can make food appear to have more protein than it does. Most of the food went to pets, but scraps were sold in February to the Indiana poultry producer, officials said. The contaminated material may have made up about 5 percent of the chickens' total food supply.
That small fraction, and the fact that people, unlike pets, do not eat the same thing day after day, suggests that consumers who ate contaminated pork or chicken would probably have ingested extremely small doses of melamine, well below the threshold for causing health effects, officials said. Experts conceded, however, that they know little about how the toxin interacts with other compounds in food.
