A few years back I was researching the latest numbers available regarding livestock concentration. Problem was, the best report (done by the University of Missouri) to track the continued consolidation of the packer industry was nowhere to be found. So naturally some calls of concern were made, and what I learned was quite alarming. The livestock sector had become so concentrated that it was now impossible to collect accurate data showing how much consolidation was actually occurring!
As of the last University of Missouri report by Mary Hendrickson and Bill Heffernan, released in April 2007, four beef packers controlled 83.5% of the market. They are Tyson, Cargill, Swift & Co. and National Beef Packing Co. The pork industry tells a similar story with an estimated 66% concentration ratio split between Smithfield Foods, Tyson, Swift & Co. and Cargill.
