These samples were examined for the presence ofSalmonellae by cultural methods and biochemical tests. The isolates were characterized using serotyping testing. As a result, nine (6.9%) of them were positive for Salmonella, in which the most common serovar were Salmonella typhimurium (6/9). The positive rates of eggs, fish, chicken, pork and beef were 11.1% (2), 10% (2), 9.5% (2), 6.9% (1) and 5.3% (1), respectively. In addition, Salmonella paratyphi (1) and Salmonella choleraesuis (2) were also isolated. Potential hazard of Salmonellosis did not be underestimated in free market. In order to reduce Salmonellosis, it is important to strengthen food sanitation management especially to animal products.
