Waterloo-Cedar Falls Courier: A Tama meatpacking plant is being bought by a Kansas City-based meatpacker. National Beef announced Monday on its website it has bought Tama-based Iowa Premium, pending conditions and a waiting period. Iowa Premium opened as Iowa Premium Beef in October 2014. With the help of $4 million in state tax credits, the company rebuilt the former Iowa Quality Beef plant, which closed in 2004, at a cost of $48.6 million.
