Californian organic dairy producer Straus Family Creamery and Horizon Organic Holding Corp, a leading brand of organic foods in the US and UK, have filed a lawsuit in the US District Court for the Northern District of California over California's Milk Stabilisation & Pooling Plans. Horizon and Straus are also seeking an injunction to prohibit the continued application of the Plans to their organic dairy operations. The complaint alleges that the Plans violate their rights to equal protection and due process, and that state-imposed pooling fees require the two companies to subsidise the conventional dairy industry.
