The Grocery Manufacturers Association (GMA) will petition US food safety regulators and bring pressure on Congress to enact labeling changes for genetically modified foods, according to a Reuters interview of Louis Finkel, executive vice president of government affairs for GMA. The campaign is an effort to avoid setting labeling requirements for GMO on a state-by-state basis, while allowing non-GMO products to be marketed with "natural" claims. Finkel says GMA is working with a broad coalition of stakeholders, including biotech crop developers, to compile the proposals. He also says the proposed legislation should be introduced soon.
