Postville, Ia. – At least 300 people were arrested today at the Agriprocessors, Inc. meat packing plant, federal officials said.

The operation, which targeted people who illegally used other persons Social Security numbers and were in the U.S. illegally, was the largest of its kind in Iowa, said Claude Arnold, a special agent with U.S. Immigration and Customs Enforcement.

The workers arrested so far were interviewed by agents with the U.S. Immigrations and Customs Enforcement (ICE) and Public Health Service. Public health officials were included to ensure that their humanitarian needs were being met, said U.S. District Attorney Matt M. Dummermuth.

Undocumented workers were paid $5 an hour for their first three or four months on the job, the employee said, and then received a salary increase to $6 per hour.

According to search warrants, ICE agents interviewed a former plant supervisor – identified as “Source 1” – in November 2007, who told them that the plant employed foreign nationals from Mexico, Guatemala and Eastern Europe. Roughly 80 percent of those workers were living illegally in the U.S., the supervisor said.
