For decades, the Hershey Co. has used sugar made from both sugar beets and sugar cane, but it decided earlier this year to stop buying beet sugar because it comes from genetically modified, or GM, seeds. Hershey communications director Jeff Beckman confirmed that the kisses and many other products stocked on shelves since Halloween no longer contain beet sugar. The company also is transitioning away from artificial to natural ingredients, he said. About 55 percent of domestic U.S. sugar is produced from sugar beets, and nearly 100 percent of the beet seeds are genetically modified to tolerate the herbicide glyphosate, the active ingredient in Roundup. Hershey is the only national brand that has dropped beet sugar, although other companies have been asking questions and there has been a lot of chatter about GM sugar on social media. Part of the pressure on Hershey came from a coalition of groups called GMO Inside that began a campaign in 2013 suggesting that consumers tell Hershey and Mars, another large candy manufacturer, to drop all GM ingredients from their products. Elizabeth O'Connell, campaigns director for Green America, one of the groups in the anti-GM coalition ... said consumer groups will continue to pressure companies to remove GM ingredients from food, or at least to label them so consumers know what they're buying. A current priority is dairy products, she said, because cows are fed mixtures of soy meal, corn and other products from GM seed.
