The nation's two biggest suppliers of organic milk are embroiled in a lawsuit. An employee responsible for milk procurement with Horizon Organics (a part of WhiteWave Foods, owned by the $13-billion dairy giant Dean Foods) quit his job in May 2012 and took a similar position with Organic Valley less than two weeks later. Horizon and WhiteWave have brought a lawsuit alleging a breach of contract and the misappropriation of confidential information and trade secrets. Larry Hansen, the former Horizon employee at the center of the dispute, is also named in the lawsuit. While employed by Horizon, he covered the West Coast region and the states of Texas and New Mexico. According to the legal filing, Hansen oversaw 48 farms that supply "over 35% of the organic milk produced for Horizon Organic."
