Americans don't know a lot about genetically modified food ingredients, but still want to be advised of any foodstuff that contains it, according to a consumer survey by the Pew Charitable Trust, a newly formed nonprofit group hoping to stimulate debate on the topic among biotech companies, green groups and federal policymakers.
The survey of 1001 consumers showed that a large number of consumers -- about 46 percent -- don't know what to make of genetically modified foods. Those who have formed an impression are evenly split: Some 29 percent believe they are safe while 25 percent believe they are unsafe.
