New research shows the Tyson Fresh Meats animal slaughtering facility in Hillsdale was the top water polluter in Illinois among major agribusiness operations in 2014.
That year, the Tyson Fresh Meats plant released over 2 million pounds of pollutants into the state's waterways, according to the Environment America Research & Education Center's report.
The environmental advocacy group examined the "water pollution footprints" of Tyson Foods and four other major agribusinesses, Cargill, JBS, Perdue and Smithfield, in Illinois and other states. Forty-four percent of the nation's pork, chicken and beef is produced by those five companies, according to the report.
Researchers analyzed the most recent 2014 data from the federal Toxics Release Inventory (TRI) on pollution discharges into waterways from the five major agribusinesses. Among the findings, Tyson's facilities released the most pollutants nationwide -- nearly 21 million pounds.
That's more pollutants "by volume than even Exxon Mobil or DuPont," according to the environmental group.
