Pinnacle Foods is planning to add 160 jobs to its plant in Fayetteville. The jobs are part of an eight million dollar expansion that will make the plant the sole production point for all Swanson frozen dinners sold nationwide. Patrick Murray, manufacturing director of frozen foods for Pinnacle, says the expansion will allow the Fayetteville plant to assume production from a plant in Omaha, Nebraska, which is closing. The Fayetteville expansion is expected to be finished by the end of the year. The expansion, which includes a new line and upgrades to two existing production lines at the plant, is the second in two years made at the Fayetteville plant to make up for production lost from the closing of Swanson facilities in Omaha.
