STUBBORN FOOD SAFETY WORRIES
The Shanghai Food and Drug Administration investigated the chicken contamination incident. It did not bring a case against Yum China and did not assess a fine.
The restaurant operator quickly responded by cutting poor performers from its poultry supplier network.

A limited-time half-price offer on buckets of KFC chicken fueled a 16 percent increase in same-restaurant sales for the first 10 days of November. But once the promotion expired, sales were down about 8 percent for the remainder of the
