ST. LOUIS — Tyson Foods Inc. plans to invest $27 million in upgrades to a prepared foods plant in Caseyville, Ill.

The Landshire Sandwiches plant was previously owned by AdvancePierre Foods before it was sold to Tyson in the summer of 2017. Tyson said it is adding three production lines to the facility which has the capability of producing 16 million lbs of product a year.

Company spokesman Derek Burleson said the upgrade would create approximately 100 jobs, with the new plant lines expected to be operational by March 2020.

According to the Northwest Arkansas Democrat-Gazette, the facility produces meat-and-cheese stuffed pretzels, tuna sandwiches, baked goods and other foods.
