Yum! Brands Inc. says there's no truth to the rumor that its Chinese division is being implicated in the investigation of a supplier of mislabeled, tainted mutton. Said the company’s SVP and chief public-affairs officer, Jonathan Blum, “Somehow, a rumor became the story, and there’s no truth to it,” Blum said. The story originated with a wire service report about a raid on a wholesale market selling packages labeled “New Zealand mutton.”
