Regulators and many scientists say these pose no danger. But as Americans ask more pointed questions about what they are eating, popular suspicions about the health and environmental effects of biotechnology are fueling a movement to require that food from genetically modified crops be labeled, if not eliminated. The most closely watched labeling effort is a proposed ballot initiative in California that cleared a crucial hurdle this month, setting the stage for a probable November vote that could influence not just food packaging but the future of American agriculture. Tens of millions of dollars are expected to be spent on the election showdown. It pits consumer groups and the organic food industry, both of which support mandatory labeling, against more conventional farmers, agricultural biotechnology companies like Monsanto and many of the nation’s best-known food brands like Kellogg’s and Kraft.
