FILE - In this April 24, 2014, file photo,, Katie Spring rolls up plastic that was used to cover certain plants during the winter in a field at the Good Heart Farmstead in Worcester, Vt. Spring and her husband Edge Fuentes, who both own the farm, back the GMO labeling bill passed by the Vermont legislature. Genetically modified foods have been around for years, but most Americans have no idea if they are eating them. The Food and Drug Administration says they don't need to be labeled, so the state of Vermont has moved forward on its own. On May 8, Gov. Peter Shumlin signed legislation making the state the first to require labeling of GMOs _ technically genetically modified organisms. (AP Photo/Wilson Ring, File) less
