Farmer owned. Community loved. Since 1933. Our farmers pledge: no artificial growth hormones (no significant difference has been shown in milk from cows treated with the artificial growth hormone rbST and non rbST treated cows). A farmer-owned brand of Dairy Farmers of America. Pasteurized. Reiter Dairy is 100% owned by a dairy farm cooperative that includes family farms right in your community. Bringing fresh, high-quality dairy to families like yours is our farmers' purpose and passion.
