Consumers are saying NO to GMOs: In some cases, consumers have made up their minds before scientists have reached consensus, but many restaurant customers are declaring genetically modified organisms to be deal killers for dining. Consumers agree with calls for clearly labeling GMOs on menus and food packaging; some will go further and gravitate toward restaurants that advertise a GMO-free menu. That will be a major issue for the nation’s food supply, since many crops—particularly soy fed to livestock and other animal feeds—have been modified to boost their yields and productivity.
