This was just released yesterday from a committee chaired by Fred Gould:

"This consensus report examines a range of questions and opinions about the economic, agronomic, health, safety, or other effects of genetically engineered (GE) crops and food. Claims and research that extol both the benefits and risks of GE crops have created a confusing landscape for the public and for policy makers. This report is intended to provide an independent, objective examination of what has been learned since the introduction of GE crops, based on current evidence."
