The U.S. Immigration and Customs Enforcement agency visited Swift & Co. meat-processing plants yesterday as a follow-up to the Dec. 12, 2006, raids. During those raids, 1,300 workers across six plants were charged with immigration violations. A company spokesperson confirmed that ICE arrested three workers at four of the Swift plants.

Swift officials said it was not exactly a "raid", rather a "routine follow-up investigation." The company was not given advanced notice. Two of the workers were taken from the Cactus, Texas, plant. For perspective, ICE agents arrested 295 workers from that plant on charges of immigration failures there in the December raids, reports Charges on the employees have not yet been released. Swift has not been implicated in any wrongdoing. 

ICE agents also visited a Greeley, Colo., beef-processing plant, a pork-processing in Marshalltown, Iowa, and arrested no one at either plant. One worker was arrested at a pork-processing plant in Worthington, Minn.

The December raids cost Swift an estimated $50 million in recovery costs.
