Consumers and GM Food Labels : Providing Information or Sowing Confusion?

Abstract

Labeling policies for genetically modified (GM) foods are under intense scrutiny and development worldwide. The fact that Codex Alimentarius Commission (Codex) -- the international body primarily responsible for food standards including labeling practices -- has been unable to reach consensus on GM food labeling is indication enough that this has been a rather contentious issue. Consumers, on the other hand, appear to be in agreement about the need for labels, if public opinion surveys are any indication. If labels are indeed implemented, what sorts of labels would be useful and under what conditions? What do we know about consumers' use of labels and their effectiveness?
