As cattle supplies dwindle, Tyson Foods is permanently closing its plant in Denison, Iowa. The plant closing will result in a loss of 400 jobs to the area, says Omaha’s KETV. Tyson said it’s reducing its beef production due to a continued lack of available cattle. The company said while it plans to close the plant, it will keep the rendering operation open. Workers impacted by the cuts are being offered work at other Tyson plants. The beef plant opened in 1961. It was the first plant operated by Iowa Beef Packers. IBP was purchased by Tyson Foods in 2001. Tyson is a multinational corporation based in Springdale, Arkansas.
