Wal-Mart has been caught selling diseased pork ribs, reported National Business Daily on Tuesday.

Regulators of the animal husbandry sector in Dazhou, Sichuan province, found in a routine inspection this January that some pork ribs in Wal-Mart's cold storage warehouse were from diseased pigs, local media reported.

This incident took place not long after the company's Chongqing "green pork" scandal last year, where Wal-Mart was fined for labeling ordinary pork as "green pork" in a number of its outlets in Chongqing. The "green pork" scandal had caused the company an unprecedented crisis of confidence.

An officer of the Dazhou Animal and Health Inspiration Station confirmed the incident to National Business Daily.

Wal-Mart Stores Inc told the newspaper that the company has attached great importance to this incident and a task force guided by company headquarters has been established. All pork products related to the incident have been removed from shelves immediately, and cooperation with the suppliers have ended.

Meanwhile, Wal-Mart is cooperating with local government departments to work on this matter.
