“In 2014, the state of Vermont passed a mandatory genetically modified (GM) ingredient labeling law that requires most human food products containing GM ingredients to include on-pack labeling as of July 2016. To comply with that law, Mars is introducing clear, on-pack labeling on our products that contain GM ingredients nationwide.”Notice that a law was passed in one state, Vermont. Mars is not doing this out of the concern for human health. Let's just make that clear.
General Mills will also label GMO ingredients in its products. Vermont's law about GMO labeling will take effect in July 2016.
