Figuring Out What's In Your Food
Consumers Are Left To Wonder Which Genetically-Modified Foods They Might Be Eating

CBS) According to a recent CBS News/New York Times poll, 53 percent of Americans say they won't buy food that has been genetically modified. But CBS News chief investigative correspondent Armen Keteyian reports that it's not that easy to avoid. While most packaged and processed foods do contain genetically modified ingredients, the labels don't have to say so.

Robyn O'Brien teaches her kids to keep a close eye on the labels of the foods they eat.

"In terms of labeling," she says, "they're not always comprehensive and thorough."

What concerns parents like O'Brien is not what's listed, but what is not. Particularly foods made with genetically modified organisms - or GMOs.

"My concern as a mother is, are these kids part of a human trial that I didn't know that I had signed them up for," O'Brien says.
