Tyson is one of the largest meat producers in the world, with 123 processing plants and 124,000 employees just in the U.S. The company did about $52.94 billion in revenue last year, but the Union of Concerned Scientists (UCS) says it came at a hefty environmental cost. 

A new report from UCS, a nonprofit organization made up of scientists, analysts and policy experts, says Tyson Foods has released billions of gallons of wastewater into U.S. waterways that have been filled with some heinous substances, including nitrogen and phosphorus, which can deplete the oxygen in water, animal body parts and byproducts, like blood and feces, and pathogens and microorganisms, including E. coli.
