Japan, the last major importer in Asia still holding out against genetically-modified corn for food use, could soon be buying more GMO material from US farmers as record prices force it to turn to cheaper modified grains. The world’s largest corn importer has long bought GMO corn for animal feed, but buys only a trickle for human food use. But food makers are caught between US farmers demanding a higher premium for GMO-free corn and Japanese grocers and consumers, the last in Asia still resisting modified crops after South Korean processors last month bought GMO corn.
