Yum's China restaurant sales drop as chicken scare hurts KFC

KFC parent Yum Brands Inc on Monday reported a 6 percent drop in fourth-quarter sales at established restaurants in China after a food safety scare ensnared some of its chicken suppliers in its top market.

Yum warned in early January that fourth-quarter, same-restaurant sales for China would fall 6 percent after excessive levels of chemical residue were found in chicken from some of its suppliers.
