BATTLE CREEK, MICH. — The Kellogg Co. is planning to close its snack plant in Columbus, Ga., by the end of 2015. The move is part of “Project K,” the company’s four-year restructuring program. It will affect approximately 325 positions.

The plant, where Kellogg makes Cheez-It crackers along with restaurant-pack graham crackers and saltines crackers, originally was opened in 1953 as a Sunshine Biscuits facility. Keebler Co. acquired the plant in 1996, and it became part of Kellogg in 2001 when the company bought Keebler.

“We will be making more effective use of our U.S. snacks network by moving production to other plants in the Kellogg snacks network, including our facilities in Kansas City, Kas.; Cary, N.C.; and Jackson, Tenn.,” said Kris Charles, spokesperson for Kellogg.

Earlier this year, Kellogg said it would close its snacks plant in Charlotte, N.C., and eliminate two production lines at its snacks plant in Cincinnati by the end of the year as part of its Project K efficiency program. The Charlotte plant produces Famous Amos, Austin Sandwich Cremes and Iced Animals cookies.
