Tyson Foods is the largest chicken, beef, and pork processor and marketer in the world. As of September 30, 2017 Tyson Foods has ~122,000 employees world wide. Tyson Foods was founded in 1931 by John W. Tyson in Springdale, Arkansas.
During the post World War II period the poultry industry was under a lot of pressure from the post-war economy and from a chicken disease out break. Tyson Foods began buying up surrounding poultry producers to mitigate their risk of bankruptcy and from being bought out by larger companies. In 1957, Tyson Foods officially controlled each step of its operations after the completion of its first chicken processing plant in Springdale, Arkansas.
