Fight over GM crops on California ballot

A high-stakes food fight in California is getting more heated. A proposal to require labeling of foods with genetically engineered ingredients has qualified to appear on the state ballot Nov. 6.

That puts California on the front line of a national fight over genetically engineered crops. Such crops have had their DNA artificially altered by genes from other plants, animals, viruses or bacteria, says Stacy Malkan, a spokeswoman for the California Right to Know group, which launched the ballot measure.
