What it would do: Require most genetically engineered processed foods and produce sold in supermarkets and other retailers to be labeled as such. GMO foods also will be prohibited from using the phrase “natural” on their labels. Meat, dairy, alcohol and restaurant foods are exempt.

Support: Consumer groups and the organic food industry say the measure gives shoppers more information about what they’re eating and allows them to decide whether they want to buy food made with genetically modified ingredients.
