The U.S. Department of Agriculture has recalled 143 million pounds of frozen beef from a Southern California slaughterhouse that is being investigated for mistreating cattle.
Officials say it's the largest beef recall in the United States, surpassing a 1999 ban of 35 million pounds of ready-to-eat meats.
The federal agency says the recall will affect beef products dating to February first, 2006, that came from Chino-based Westland-Hallmark Meat Company.
Officials say the company supplies meat to the federal school lunch program and to some major fast-food chains.
