Chinese police detained six executives from Shanghai Husi Food, which reportedly supplied tainted meat to McDonald’s and KFC-parent Yum! Brands (YUM.NYSE), Reuters reported, citing state media. Official Xinhua News Agency reported that Shanghai’s chief of police and deputy mayor Bai Shaokang told local radio that the executives of Shanghai Husi Food, a unit of U.S.-based OSI Group, had been taken into custody. Regulators closed the Shanghai Husi plant on July 20. After the scandal broke, Yum quickly cut all ties with OSI, which was not a significant supplier to the chain. McDonald’s, which was much more dependent on the supplier, also ended its relationship with OSI China.
