A group of organic dairy farmers in Maine has formed its own company with its own brand of milk. Shoppers soon will be able to buy MOOMilk – short for Maine’s Own Organic Milk – at stores in Maine and Massachusetts. The dairy farms – from Aroostook, Penobscot, Kennebec and Washington counties – formed a cooperative after not having their contracts renewed with the H.P. Hood milk company. They then launched their own company, Maine’s Own Organic Milk Co. MOOMilk’s general manager, Bill Eldridge, says the milk should start appearing in stores in November.
