The “use-by” and “best-by” dates printed on milk cartons and gallon jugs may soon become a thing of the past, giving way to more accurate and informative QR codes.

In the U.S., dairy products are among the top three food groups with the largest share of wasted food, said Samantha Lau, a doctoral student in food science who works in the lab of Martin Wiedmann, the professor of food safety in the College of Agriculture and Life Sciences.
In the early spring semester, Lau, also working with Cornell’s Milk Quality Improvement Program, connected with the Cornell Dairy Bar, which sells fluid milk in addition to ice cream on campus. She wanted to assess consumer acceptance for QR code
