Fertilizer companies commonly add melamine to their products because it helps control the rate at which nitrogen seeps into soil, thereby allowing the farmer to get more nutrient bang for the fertilizer buck. But the government doesn't regulate how much melamine is applied to the soil. This melamine accumulates as salt crystals in the ground, tainting the soil through which American food sucks up American nutrients.
A related area of agricultural concern is animal feed. Chinese eggs seized last month in Hong Kong, for instance, contained elevated levels of melamine because of the melamine-laden wheat gluten used in the feed for the chickens that produced the eggs.
To think American consumers are immune to this unscrupulous behavior is to ignore the Byzantine reality of the global gluten trade. Tracking the flow of wheat gluten around the world, much less evaluating its quality, is like trying to contain a drop of dye in a churning whirlpool.
More ominous, the United States imports most of its wheat gluten. Last year, for instance, the F.D.A. reported that millions of Americans had eaten chicken fattened on feed with melamine-tainted gluten imported from China. Around the same time, Tyson Foods slaughtered and processed hogs that had eaten melamine-contaminated feed. The government decided not to recall the meat.
Only a week earlier, however, the F.D.A. had announced that thousands of cats and dogs had died from melamine-laden pet food. This high-profile pet scandal did not prove to be a spur to reform so much as a red herring. Our attention was diverted to Fido and away from the animals we happen to kill and eat rather than spoil.
Frightening as this all sounds, the concerned consumer is not completely helpless. We can seek out organic foods, which are grown with fertilizer without melamine -- unless that fertilizer was composted with manure from animals fed melamine-laden feed (always possible, as the Tyson example suggests).
We could further protect ourselves by choosing meat from grass-fed or truly free-range animals, assuming the grass was not fertilized with a conventional product (something that's also very hard to know).
But as all the caveats above indicate, these precautions will only go so far. Melamine, after all, points to the much larger relationship between industrial waste and American food production. Regulations might be lax when it comes to animal feed and fertilizer in China, but take a closer look at similar regulations in the United States and it becomes clear that they're vague enough to allow industries to "recycle" much of their waste into fertilizer and other products that form the basis of our domestic food supply.
