Sen. Mark Begich, D- Alaska, is urging a major international food contractor that has multi-million dollar contracts with the federal government to reconsider its decision to serve only Marine Stewardship Council certified seafood to federal agencies.

Begich said in a letter to George Chavel, president and chief executive officer of Sodexo USA that he applauds the company’s commitment to sustainability, but is deeply concerned by reports that Sodexo USA only sources seafood certified by a single broker: the Marine Stewardship Council.

Begich took issue with reliance on sustainability certification from London-based MSC, an organization that has come under harsh criticism by Alaska fishermen for their growing logo fees, inconsistent standards and increasing licensing costs.

“Alaska was into sustainability before sustainability became cool,” he said.
