Springdale, Arkansas-based Tyson Foods, the world's largest processor and marketer of beef, chicken and pork, has unveiled its plans to restructure its live swine operation in order to more effectively position the group for the future. The restructuring will result in the elimination of approximately 200 jobs, the closure of company-owned and leased hog farms, and discontinuing relationships with 132 contract hog producers in Arkansas and eastern Oklahoma. All together, 159 farms will be affected.
