California to vote on GM food labeling

California could become the first US state to enforce labeling of genetically modified (GM) foods, in a vote next month pitting agro-chemical giants against opponents of so-called “Frankenfoods.”

The western state will vote on November 6 — the day of the White House election — on Proposition 37, which backers claim would simply let consumers know what they are eating, but critics say will pander to unjustified fears.
