Abstract

Californians will soon vote on Proposition 37, mandating that genetically modified (GM) food is labeled. Supporters argue that mandatory labeling responds to consumers' rights, offers greater choice, and provides more information on food content. But the specifics of Prop 37 will result in a much different outcome. Food category choice will decrease and the added labeling information will be imprecise. Prop 37 will introduce a double standard for accidental GM purity in organic versus non-organic foods, favoring organic.
