A proposed class action federal lawsuit alleges nine companies colluded to inflate consumer pork prices. The lawsuit claims the defendants, including Hormel, Tyson Foods, JBS USA and Smithfield Foods, forced consumers to pay higher prices for bacon, ham and other pork products by coordinating output and limiting production, as well as exchanging competitively sensitive and closely guarded non-public information about prices, capacity, sales volume and demand, reported The Wichita Eagle.
