In November, California voters will decide on a ballot initiative that would require labeling of all foods containing ingredients from genetically modified crops. The initiative made it to the ballot after almost 1 million Californians signed a petition in favor of it—nearly double the 504,760 signatures needed under the state's proposition rules.
