U.S. farmers are in a near panic because of growing uncertainty over genetically modified crops, and the American Corn Growers Association has even claimed that multinational seed and chemical companies “misled” farmers by encouraging them to plant millions of acres without warning them that the crops don’t have consumer acceptance. In the past month, Japan’s two biggest breweries, a major Mexican corn tortilla maker, and a large U.S. pet food maker said they would no longer use certain genetically modified corn varieties. U.S. activists have started following the lead of European enviros, uprooting fields of gene-altered plants during midnight raids at company test plots in California, Maine, Minnesota, and Vermont.
