The meat is kosher, but the conditions?

The New York Times's immigration reporter, Julia Preston, today has a troubling story about the kosher meatpacking plant in Postville, Iowa that was raided by the feds in May. Preston, who travelled to Iowa and interviewed workers, reports allegations of "pervasive labor violations." An excerpt:

"Elmer L. said that he was clearing cow innards from the slaughter floor last Aug. 26 when a supervisor he described as a rabbi began yelling at him, then kicked him from behind. The blow caused a freshly-sharpened knife to fly up and cut his elbow. He was sent to a hospital where doctors closed the laceration with eight stitches. But he said that when he returned, his elbow still stinging, to ask for some time off, his supervisor ordered him back to work."
