Ben & Jerry's has made a pledge to remove all GMO ingredients from its ice cream. The company has taken a vocal stand in recent years in support of states looking at legislation that would require manufacturers to disclose food that is made with genetic engineering. And Vermont recently passed a law that will require labeling starting in 2015. Ben & Jerry's co-founder Jerry Greenfield [then] launched a campaign to help fill the coffers of Vermont's crowd-sourced defense fund set up to combat lawsuits over its labeling law. Some other mainstream companies are carefully - and much more quietly - calibrating their non-GMO strategies. General Mills' original plain Cheerios are now GMO-free, but the only announcement was in a company blog post in January. Grape Nuts, another cereal aisle staple, made by Post, is also non-GMO. And Target has about 80 of its own brand items certified GMO-free. Megan Westgate runs the Non-GMO Project, which acts as an independent third-party verifier of GMO-free products, including Target's. She says her organization knows about "a lot of exciting cool things that are happening that for whatever strategic reasons get kept pretty quiet." The Non-GMO Project has certified more than 20,000 products since it launched in 2007, and Westgate says this is one of the fastest growing sectors of the natural food industry, representing $6 billion in annual sales.
