California voters who cast ballots on Tuesday didn't embrace Proposition 37, a measure that would have mandated labeling breakfast cereals, baked goods, and other processed foods containing genetically modified ingredients, NBC News reports. A dozen similar initiatives have been struck down this year in other states. Proponents argue that consumers deserve transparency to allow them to make informed choices. Opponents fear that labeling will dissuade customers from purchasing bioengineered food, even if it doesn't differ from non-GMO items in terms of taste, texture, or nutritional content. The onus would be on grocers to ensure that their shelves were stocked with appropriately labeled products. A citizen's petition, which is pending before the U.S. Food and Drug Administration, aims to enforce these requirements nationwide.
