"What happened at Husi Shanghai is completely unacceptable," said Sheldon Lavin, chief executive of privately held OSI Group.



Yum Brands, the parent of KFC, Taco Bell and Pizza Hut, said on Wednesday it had stopped buying food from OSI in China, Australia and the United States after Shanghai police detained five people connected to the meat supplier's factory. OSI was not a major supplier of Yum, according to the restaurant.



Starbucks also is severing its relationship with the OSI's unit Husi after it had to pull chicken-apple panini sandwiches from stores in some Chinese markets, including Henan, Yunnan, Jiangxi and Guizhou, Bloomberg reported.
