July 23 (Reuters) - Yum Brands Inc's China division has stopped buying from OSI China, after Shanghai police detained five people connected to the meat supplier's factory at the center of a new food safety scandal, Yum said on Wednesday.
"Yum China has decided to immediately terminate all procurement from OSI China," including Shanghai Husi Shanghai Husi Food Co Ltd, Yum said in a statement.
China is the No. 1 market for Yum, whose nearly 6,400 restaurants there are mostly KFC outlets.
Yum's China restaurants, which also include Pizza Hut, have arranged alternative suppliers, and the company said it did not expect any disruptions to its KFC business there.
OSI is not a major supplier to Yum China, the company said.
The five people detained include the head of Shanghai Husi and its quality manager, police said in a statement.
Shanghai Husi on Sunday was the subject of a Chinese TV expose that showed staff at the plant using expired meat and picking up meat from the floor to add to product mixes.
Before the arrests, the official Xinhua news agency cited the Shanghai food and drug watchdog as saying that food safety violations at Shanghai Husi were company-led rather than the acts of individuals.
Yum said in its statement: "It is difficult to believe and completely unacceptable that the management of Shanghai Husi, a division of OSI, would oversee and organize illegal and dishonest operations."
Shares of Yum were up 0.4 percent at $75.15 on Wednesday.
Yum, McDonald's Corp and Starbucks Corp are among the global brands that have pulled products from their outlets after it emerged that Shanghai Husi supplied expired meat to clients in China, as well as Japan, in the latest in a series of food safety scandals in the country.
