Abstract: 

Broiler carcasses are considered to be the major source of salmonella detection and enumeration of salmonella in this product are two criteria for evaluation of hygienic quality of the slaughterhouses and the product itself. In this study, contamination of broiler carcasses produced in poultry Industrial slaughterhouses in Tehran province was assessed using three tube MPN methods. According to our results 69 percent of the samples were salmonella positive while not detected the salmonella in the rest of samples. Enumeration of salmonella per carcass indicated that the average number of salmonella in 62/72 of salmonella positive carcasses was 49/5 and in 7/6 percent 2605 and in 16/48 percent 279/5 and in 2/3 percent upper 3300. Our results also showed that number of salmonella per per gram and cm2 of positive carcasses in 93/42 percent were 0/054 MPN /gr and 0/047 MPN/cm2 and in 4/38 percent 1/695 MPN/gr and 1/4 MPN/cm2 and in 1/5 percent upper 1/7 MPN/gr and 1/5 MPN /cm2. The statistical analysis in this study results and calculates the ratio and average indicates that the mean contamination of carcasses exanimate was low although frequency contamination was high.
