Opponents of genetically modified foods are making headway in California with a proposed ballot initiative that would require food companies to label many products containing such ingredients.Backers of the initiative, including consumer activists and organic-food groups, said Wednesday they had submitted nearly double the number of signatures required by the state to place the proposal on the Nov. 6 ballot. California officials will take at least several weeks to certify the initiative, but people on both sides of the issue expect it to appear on the ballot. 

Supporters of a proposal to require labeling for genetically engineered foods sold on California shelves took a step toward qualifying for the ballot by submitting nearly a million signatures today.Initiative proponents announced today that they submitted 971,126 signatures to county election officials across the state. Roughly 504,000 valid voter signatures are needed to qualify for the November ballot."We're very confident that we'll be on the ballot in November," spokeswoman Stacy Malkan said.
