New York’s attorney general says Tyson Foods is refusing to comply with a subpoena for a civil probe into possible price gouging during COVID-19. Letitia James asked a state judge in Manhattan to make Tyson turn over materials like contractual terms, prices, and profit margins for its meat sales to New York retailers between December 2019 and April 2022.

James says Tyson, one of the largest U.S. meat producers, stopped complying after giving limited information based on the company’s argument that New York’s price gouging law didn’t apply to meat products brought in from outside the state. James called that “novel and unfounded,” pointing out in a recent court filing that it can only be tested by examining the same materials that Tyson now refuses to hand over to her office.

Reuters says Tyson declined to comment on the subpoena, saying it raised meat prices to offset soaring labor and feed costs.
