A coalition of nonprofit consumer safety and environmental groups sued the Food and Drug Administration (FDA) in the U.S. District Court for the Northern District of California on December 21, 2011. The coalition is led by the International Center for Technology Assessment (ICTA), and includes Friends of the Earth, Food and Water Watch, the Center for Environmental Health, the ETC Group, and the Institute for Agricultural and Trade Policy. ICTA states that its lawsuit “demands” FDA respond to the coalition’s 2006 petition. The 2006 petition requested FDA take several actions, including requiring specific product labeling and health and safety testing; analyzing the environmental and health impacts of nanomaterials in products approved by FDA; and regulating sunscreens containing nanomaterials. In the December 21, 2011, complaint, the coalition states that, since 2006, “nanomaterial consumer products have continued to proliferate without oversight.” The coalition asks the court to order FDA to respond to its 2006 petition without further delay.
