SPRINGDALE, ARK. — Tyson Foods, Inc. is exploring the sale of its TNT Crust pizza crust business as part of its “strategic focus on protein,” Tyson said.

The sale would include the TNT Crust’s business of partially baked crusts, flat breads and self-rising crusts as well as the company’s two manufacturing facilities in Green Bay, Wis. Tyson would retain the tortilla production from the facilities that will be used in other parts of its business, Tyson said.

“We’re focused on maximizing the full potential of our core business, and this divestiture will help pave the way for growth in our protein brands,” said Sally Grimes, group president of Prepared Foods for Tyson. “We believe a potential buyer will see the value of the pizza crust business as a whole, including the TNT Crust brand, the facilities and the talented team members, and will be able to focus on its future.”

Tyson recently agreed to sell Circle Foods L.L.C., producer of flatbreads, tortillas and Mexican food products, to Ajinomoto Co. Inc.
