On a somewhat related note, Tyson just lost a class action lawsuit in Federal Court to cattle producers that claimed their subsidary, IBP, had depressed beef prices in the Southeast. Needless to say Tyson is appealing this...

the jury found that Tyson's "conduct in manipulating and controlling the price it paid for cattle was in violation of an 80-year-old law…This should be considered an extraordinary day for cattle producers in this country."
