The effects of a health scare about chicken and hormones on China's internet sites is affecting sales of Yum Brands store outlets for Kentucky Fried Chicken (KFC) in China. As most of the stores are company owned compared to 11% in the U.S., this is having an outsized effect on Yum Brands performance. Fast growth in China can be an asset as well as a liability if not carefully handled. Food is an especially difficult field in China with careful management and control of supplies critical. The Chinese public is skeptical about government monitoring and checks of food supplies and pharmaceuticals after years of lax enforcement. Yum Brands has 5400 KFC and Pizza Hut stores in China, 14% of total global store outlets.
