One of the world’s largest meat processors shut down nearly all of its U.S. operations Tuesday as federal agents raided plants in six states in a crackdown on illegal immigrants who allegedly used stolen identification to get their jobs, reports USA Today. It was unclear how many people were arrested in the raids at Swift & Co.’s headquarters in Greeley, Colo., and its plants in Grand Island, Neb.; Cactus, Texas; Hyrum, Utah; Marshalltown, Iowa, and Worthington, Minn.
The plants have thousands of workers, and Tuesday’s massive roundup – which involved 1,000 federal agents – was one of the U.S. government’s largest moves ever against illegal workers. The raids come eight months after Immigration and Customs Enforcement (ICE) arrested 1,187 illegal workers at plants operated by IFCO Systems, a company that makes pallets. The Swift probe, which began in February, uncovered a massive identity fraud scheme, officials said.
