The ten-million-dollar loss posted by Organic Valley during 2017 is the company’s first financial loss in 20 years of operation.  Leaders say increased milk inventories, falling prices and a slowdown in sales growth are to blame.  Gross sales were up four percent to more than one-point-one-billion dollars.  The La Farge-based company is now the top national brand for organic, 100 percent grass-fed dairy and meat.  Organic Valley leaders say they plan to be the largest food company in the world powered only by renewable energy no later than next year.
