Tyson Foods says it will merge two Fayetteville plants into one in a move that could cost the community about 230 jobs. A change in the product mix will effect about 50 percent of the Entree plant, which produces value-added chicken products. The "Mexican Original" operations at one site will be consolidated into another site. Workers have been notified in accordance with federal law, the company said, but most workers effected will be offered posts in other Tyson plants. Tyson is based at Springdale and has a number of plants in the area. The "Mexican Original" plant will be closed around October, the company said. After the consolidation is finished, Tyson hopes to sell the shuttered plant.
