Ask long-time Polka Dot milk drinkers and they will tell you: there’s a difference between milk from the “big guys” and the stuff made at Hastings Coop Creamery. Every drop of Polka Dot milk is produced from raw milk shipped to the Hasting Coop Creamery by local farmers who have pledged not to use artificial growth hormones (rBST / rBGH) in their milk-producing cows.
