For all the outrage about Chinese melamine, what American consumers and government agencies have studiously failed to scrutinize is how much melamine has pervaded our own food system. In casting stones, we’ve forgotten that our own house has more than its share of exposed glass.
To be sure, in China some food manufacturers deliberately added melamine to products to increase profits. Makers of baby formula, for example, watered down their product, lowering the amount of protein and nutrients, then added melamine, which is cheap and fools tests measuring protein levels.
But melamine is also integral to the material life of any industrialized society. It’s a common ingredient in cleaning products, waterproof plywood, plastic compounds, cement, ink and fire-retardant paint. Chemical plants throughout the United States produce millions of pounds of melamine a year.
Given the pervasiveness of melamine, it’s always possible that trace elements will end up in food.
