NPR's Joe Palca reports that a new study has shown that genetically engineered foods can produce unexpected food allergies. In the study, being published in The New England Journal of Medicine, researchers found that genetically engineered soybeans could provoke an allergic reaction in people who are allergic to nuts that supplied the engineered genetic material. An editorial accompanying the study says it raises questions about the adequacy of safeguards by the Food and Drug Administration.
