Survey shows Americans in the dark regarding genetically modified foods.

Americans pay little attention to genetically modified foods, have difficulty separating fact from fiction when it comes to the science behind them, and are willing to believe unsubstantiated rumors about them.

According to a national study of 1,200 Americans commissioned by the Food Policy Institute (FPI) at Rutgers-Cook College, while most Americans say they are interested in the technology and have opinions about it, most lack the tools and background needed for an informed assessment.

Genetic modification (GM) involves the transfer of genes from one plant or animal to another with the purpose of expressing a desired trait, such as pest resistance or increased productivity. Estimates suggest that as much as 80 percent of processed foods in the United States contain a component from a genetically modified crop, such as corn starch, high-fructose corn syrup, canola oil, soybean oil, soy flour, lecithin, or cotton-seed oil.

Despite the abundance of products with GM ingredients, the FPI study found that fewer than half of Americans are aware that such products are currently for sale in supermarkets, and fewer than a third realize they regularly consume GM foods. Even those who say they are aware of GM foods are confused as to which foods are out there; the majority (79 percent) incorrectly believed that GM tomatoes are available, possibly due to Calgene's highly publicized (but now defunct) GM tomato marketing effort in the mid 1990s.

On a quiz about the basic science behind GM technology, 87 percent of Americans could not score a passing grade. Seven in 10 don't believe it is possible to transfer animal genes into plants, six in 10 don't realize that ordinary tomatoes contain genes, and more than half believe that tomatoes modified with genes from a catfish would probably taste fishy. Fewer than half understand that eating a genetically modified fruit would not cause their own genes to become modified.

"People seem to have a great number of misconceptions about the technology," says the study's lead author, Rutgers psychologist William Hallman. "As a result, they seem to be willing to believe just about anything they hear about GM foods." Most Americans find it believable that people have had allergic reactions to GM food, and more than half find it believable that a large fast-food chain used chickens so altered by genetic modification that they are not considered chickens anymore (both untrue rumors widely disseminated on the Internet).

Most Americans say they have heard little and know little about GM foods, and nearly two-thirds say they have never talked about the technology with anyone. Nevertheless, some respondents reported strong support or opposition for the technology, with 27 percent approving and 23 percent disapproving of it. However, most Americans said they were unsure or could not take a position.

Even though they lack a solid information base, most Americans report passive interest in the topic of GM food. That is, while very few have actually looked for information about GM food, most say they would be very interested in watching television shows about the technology, particularly shows addressing concern about potential risks.

The study is the third in a series funded by a grant from the USDA under the Initiative for Future Agriculture and Food Systems Program to examine consumer perceptions of agricultural biotechnology.
