C. Can Consumers Avoid G.M.O.'s?

Narrator: This is Science Today. As the controversy over genetically modified organisms, or G.M.O.'s, continues to swirl, one thing is clear - it's becoming almost impossible for consumers to avoid them. Norman Ellstrand, a professor of genetics at the University of California, Riverside, says it would be hard to avoid eating food in this country that doesn't have some portion that was genetically engineered in the last twenty-four hours.

Ellstrand: All our processed food has items in them from soybeans and corn, which the vast majority of both crops in the United States are genetically engineered now, so it's very likely that if you eat processed foods, you're going to contact something that's genetically engineered.

Narrator: Regardless of one's opinion of G.M.O.'s, Ellstrand emphasizes it's an important industry and people need to educate themselves on the topic.

Ellstrand: I think the other thing I would emphasize is nobody should listen to one person, that scientists are all specialists and each of us specialists - like the blind men of India - touch a different piece of the elephant and come up with a different view. The best way to get educated is to seek a lot of information.
