Many Americans assume that anything labeled "USDA Organic" hails from the U.S.. And for produce, at least, the assumption typically holds true, with the exception of obvious imports like mangoes or coffee beans or tomatoes in January. But the farther an item is removed from the soil, the greater the possibility it harbors ingredients farmed abroad. One needn't reach the tail end of the supply chain, where the frozen breakfast burritos dwell, to find foreign inputs. Just consider the steak in your butcher's case. A cow must jump through multiple hoops before earning USDA certification. While the animal may have grazed on chemical-free Iowa pasture all summer, what did it eat during the off-season and where were the feed's ingredients grown?
