FILE - In this Jan. 10, 2009 file photo, Holstein cows wait in the milking parlor 9 in Turlock, Calif. Consumers have been led for years to believe California cows are happy, which is why many were sickened when images surfaced of a washed-up milker, too weak to stagger to slaughter, rolled, pushed and run over by a forklift operator. The suffering cow covertly taped by the Humane Society of the U.S. prompted the biggest beef recall in U.S. history and contributed to sweeping legislation over the past 13 months designed to improve the lives of farm animals. But more important for farmers, it awakened the masses to the stark reality for many animals raised for food.
