 In 2006, the Organic Consumers Association organized a boycott of Horizon Organic (and Aurora Organic Dairy), alleging that the company was not following organic standards.In August, the Cornucopia Institute filed a complaint with the USDA alleging that Horizon Organic violated National Organic Program standards in reference to the amount of time their dairy cows should spend in pasture.As a result of the boycott, one of the largest natural food cooperatives, PCC Natural Markets in Seattle, decided to discontinue Horizon Organic products from their customer offerings.
