A federal judge has thrown out a rule allowing pork plants to speed up production lines because the U.S. Department of Agriculture didn’t properly consider the risks to workers before the rule was issued in 2019. Union officials praised Wednesday, March 31, 2021 ruling because they say faster line speeds at pork plants increase the risk of injuries for workers. (AP Photo/Michael Conroy, File)
