A new biotechnology disclosure law allows food producers to use digital codes rather than product labels to inform consumers that certain foods contain genetically modified ingredients… Nearly half of Americans say they would be much less likely or somewhat less likely to purchase a food product if they learned it contained genetically modified ingredients… “The statements mean both the participants in the survey and Americans in general because the results obtained from survey participants are used to project to the U.S. population,” said William Hallman, a visiting scholar at the Annenberg Public Policy Center and professor in the department of human ecology at Rutgers University. “Because the survey participants are representative of the U.S. population, the percentages in the statement represent the percentages of Americans in general who would have responded similarly had we had the opportunity to interview all 320 million of them.”
