The Packers and Stockyard Division is actively investigating Tyson Foods, one of the largest meat companies in the nation, according to interviews with contract growers and a USDA employee. Investigate Midwest filed a Freedom of Information Act with the USDA seeking records in May related to potential PSD actions against Tyson Foods after two former contract growers told a reporter they had been contacted by the agency. In May, Investigate Midwest reported that chicken growers who worked with Tyson were left with millions of dollars in debt after the company shuttered plants.
