Species adulteration of meat products has long been a global issue, which not only relates to import and export, but also has an impact at the retail level. In China, a number of severe events of meat adulteration were revealed in 2011, primarily with poultry or pork substituting beef or mutton. The illegal manufacturers have made prodigious profits from the secretive chain of fraudulent
