Statement by the AAAS on the safety of genetically modified foods:
http://www.aaas.org/news/releases/2012/media/AAAS_GM_statement.pdf Unfortunately this has become the equivalent of climate change denial on the left. Not so long ago, one could say that US Republicans had a near monopoly on the misrepresentation of science, but the FUD surrounding GMOs has reached the point where that is no longer the case.
Ironically, this is a situation where the many good reasons to be skeptical of the value of GMO technology - concerning its political and economic effects - are buried under a mountain of fake debate. In the long run, GMO opponents are hurting their own cause.
