MONTPELIER, Vt., May 8 (UPI) -- Governor Peter Shumlin signed into law yesterday a bill that makes Vermont the first state in the country to require the labeling of all GMO foods and prohibiting the use of the terms "natural" and "all natural" on foods containing any genetically modified ingredients.
Several other states have passed similar bills, but due to the prohibitive cost of enforcing such regulations, the laws only take effect when neighboring states agree to similar legislation.
