Clarification: In the Dec. 5, 2013, edition of The Daily Illini, the article “UI Dining Services uses local, sustainable sources” stated that 686,000 gallons of milk are collected from on-campus cows. Prairie Farms is the only company to have a contract with and handle the University’s dairy products. The milk is collected and processed by Prairie Farms and sold back to the University. The Daily Illini regrets the error.
