An injunction in the case of Center for Food Safety v. USDA in September, 2010 prevented farmers from planting Roundup Ready sugar beets across the United States until a remedial environmental impact report could be filed, prompting some fear of a sugar shortage.[10] The USDA completed an environmental impact study of Roundup Ready sugar beets in 2012 and concluded that they are safe, at which time they were deregulated.[11]
