Based on Law no. 18/2009 of the Republic of Indonesia concerning Animal Husbandry and Animal Health that food of animal origin must be safe, healthy, whole and halal. From one aspect, the content of pork and rat meat in processed food products is an act of counterfeiting that is detrimental to consumers and this is against the law because of allergy and halal issues. In practice, meat adulteration by means of mixing pork or rodent derivatives with beef or chicken had been frequently detected by using molecular technology in some market in Java, Indonesia. Unfortunately, very rare information has been available in Bali and Nusa Tenggara. The purpose of this study was to confirm the meat adulteration issues in the region, by analyzing the surveillance data provided by the Disease Investigation Center Denpasar Indonesia. A total of 181 various kinds of samples were collected during active and passive surveillance, although only 85 samples consisting of various animal products namely meatballs, sausages, burgers and fresh meat were analyzed and reported in this study. The method used to obtain the samples were food safety key indicators approach and tested to detect species-specific, cytochrome b (cyt b) coding genes of porcine and rodent. For this, genomic DNA of porcine and rodent were isolated and subjected to PCR amplification using specific set of primers for each animal species. The PCR test showed that a box of meat sample that was previously thought to be beef was PCR positive to contain porcine DNAs. However, all of the animal products tested were negative PCR, suggesting no evidence of pork and rodent meat ingredients in the processed foods tested. It was concluded that the molecular technique could specifically be used to confirm meat counterfeit. This finding confirmed there was a degree of security guarantee for meat adulterations in processed food but not in fresh beef which has medical aspect for allergic consequences and halal fatwa.
