Detection of species adulteration in meat products is important for consumer protection and food labeling law application. The threat and risk of food adulteration and mislabeling have become a large concern and challenge for the food control authorities and consumers. In this study 10 samples of Luncheon (beef) and 10 samples of Corned beef were collected from the local markets in Kafrelsheikh Governorate and examined for mislabeling detection by means of multiplex PCR. Results showed that 8 of the 10 samples Luncheon and all the 10 samples Corned beef were adulterated with goat's meat, while one sample of Luncheon was adulterated with equine meat, which were not in compliance with the label on the examined product. So, a strict national program by the concerned authority is required to protect consumers and prevent adulteration of food stuff.
