Abstract
The present work intends to use a mPCR for simultaneous detection of Bos taurus, Bubalus bubalis and Salmonella spp. in samples commercially available on Marajó Island, Pará State, Brazil. For this purpose, a mPCR reaction with different concentrations of DNA and primers with different annealing temperatures was optimized. Next, 28 samples of ground meat marketed as being of bovine origin were collected and a mPCR for the determination of species and for the detection of Salmonella spp. were realized. The results demonstrated the efficiency of the proposed technique for identification of Bos taurus, Bubalus bubalis and Salmonella spp. We conclude that the proposed mPCR technique is efficient and that buffalo meat is marketed as bovine on the Island of Marajó and that such frauds violating the current legislation that normalizes the commercialization of ground beef.
