Circle Foods, an Otay Mesa-based maker of tortillas and other Mexican foods, was acquired by Tyson Foods for an undisclosed price, Tyson said.

Tyson, a $33 billion company based in Springdale, Ark., and best known for its chicken production, said it acquired Circle from Claridge Inc., a Montreal-based private equity firm.

Circle has a 159,000-square-foot factory with about 600 full-time employees. Tyson said it doesn’t plan any significant changes and that it intends to retain the existing management and production team.

Circle makes branded products that include Nuevo Grille, Tortillaland, and Rotiland. The company’s plant that was built in 2008 produces burritos, chimichangas, enchiladas, quesadillas, tacos, tamales, as well as tortillas and Indian flatbreads.

Private equity firm Claridge is owned by the Stephen Bronfman family of Canada. In addition to its portfolio of companies in the real estate and entertainment industries, it has investments and equity stakes in such food businesses as Plats Du Chef of Montreal and La Terra Fina of California.
