Des Moines Register: It’s Hy-Vee’s turn to sue over alleged price fixing in the pork industry. Following a well-worn playbook, the West Des Moines-based grocer has filed a lawsuit against the country’s biggest meatpackers as well as a data firm accused of enabling collusion between them. The lawsuit alleges that the firm, Agri Stats, sold detailed reports to the packers that revealed how many pigs their competitors were raising and slaughtering. The upshot, the lawsuit contends: Meatpacking giants like Tyson Foods and Smithfield Foods used the reports to decrease the amount of pork on the market and raise prices, violating antitrust laws.
