SAN ANTONIO — C.H. Guenther & Son, a producer of branded and private label grain-based and other specialty food products, has added two longtime food industry veterans as senior advisers.

Kevin Hunt brings to his advisory role more than 45 years of senior management and food industry experience. Mr. Hunt most recently was president and chief executive officer of Ralcorp Holdings. In addition to working at Ralcorp and its predecessor entities for more than 25 years, Mr. Hunt has held positions at American Home Products Corp. and Morton-Norwich Products.

Mr. Hunt also is on the board of directors at Clearwater Paper Corp. and Energizer Holdings.

Stan McCarthy joins C.H. Guenther as an adviser after most recently holding the post of c.e.o. at Kerry Group. Mr. McCarthy had been with Kerry for more than 40 years in various finance and management positions. He is a member of the board of directors at Ryanair Holdings.

“Kevin and Stan come to us with tremendous experience in the food industry and a wealth of knowledge that will help us to continue to innovate and support our customers,” said Dale Tremblay, c.e.o. of C.H. Guenther & Son. “We are thrilled to add individuals with Kevin’s and Stan’s track records of success to the CHG family.”

Founded in Texas in 1851, C.H. Guenther & Son employs more than 3,000 people in 21 manufacturing locations in the United States, Canada and Western Europe. The company was acquired earlier this year by a group led by PPC Partners in partnership with co-investors and management. Pritzker Group formed PPC Partners on April 2 to buy C.H. Guenther and other “middle market companies.”
