Meanwhile, a manager at a KFC in Beijing's Chaoyang district who gave his name only as Feng said on Sunday that all of the restaurant's chicken is supplied by "qualified manufacturers in Shandong province, not Shanxi".
"Business has been as usual, and there's been no decline in sales since the report," he added.
KFC Corp posted a statement on the micro-blogging website Sina Weibo that said only about 1 percent of its chickens are supplied by Suhai Group, and those that they receive pass quality checks.
McDonald's also said on Sina Weibo that Suhai Group is not its current supplier.
