Yum and McDonald's profits drop after supplier scandal

5. Pizza Hut

When Shanghai Husi Food Co was shut down, Pizza Hut was also found in the list of chains that have been using the expired meat.

Yum! Brands, which owns Pizza Hut, said that they have halted buying meat products from the Shanghai supplier, and reiterated that they have zero tolerance for illegal behavior in food safety.

The fast-food chain's Chongqing location last year has also been reported to serve customer 'expired food'. A woman bought one serving of fried rice only to find it not only to be the wrong order, but also a plate of cold food that was cooked four hours ago. The angry customer accused the famous chain to be 'indifferent toward customer's health'.
