"A measure that would require most foods made with genetically engineered ingredients to be labeled in California was significantly behind early Wednesday."

"Supporters of Proposition 37 said consumers have a right to know whether food has been genetically altered, particularly when the long-term health impacts are unclear. Opponents argued that the labels would stigmatize foods that are scientifically proven to be safe.

With more than 94 percent the precincts reporting, voters rejected the proposed labeling law. California would have been the first state in the nation to pass such an initiative."
