A federal judge has certified a nation-wide class-action lawsuit for farmers who claim beef packers conspired to lower prices for their csttle.
The judge dismissed U.S. Premium Beef shareholders from the lawsuit, but certified it against Tyson Foods, JBS, Cargill and National Beef for cattle they bought between June 1, 2015, and Feb. 29, 2020.
The judge refused certification for traders and suppliers of feeder cattle.
He rejected a motion from the packers to have expert witness Dr. Basil Lamb dismissed from testifying for the farmers.
