Beijing's food safety and quality watchdog has responded to media reports that duck meat was found in mutton for sale in a local wholesale market, Beijing News reported on Monday.

The largest mutton and beef wholesale market, Xinfadi, in South Beijing's Fengtai district, was reported to have sold mutton mixed with duck meat.

The average price of sliced mutton is 56 yuan ($9.15) per kg. However, when sold to hot pot restaurants, the price went down to 20 yuan per kg.
