But there is no reliable evidence that genetically modified foods now on the market pose any risk to consumers.
The Food and Drug Administration says it has no basis for concluding that foods developed by bioengineering techniques present different or greater safety concerns than foods developed by traditional plant breeding. Nevertheless, bills are pending in several states to require mandatory labeling of genetically modified ingredients (a referendum to compel such labeling was narrowly defeated in California last November). For now, there seems little reason to make labeling compulsory.
Consumers can already find products free of genetically engineered ingredients, with labels voluntarily placed by the manufacturers.
