The study aimed to isolate and compare the incidence and the count of salmonella. The results showed that the mean values of salmonella in crop skin of the chickens of large and small companies were 2.143 and 1.926 log10 cfu/g, respectively. The mean values of salmonella in under wing of the chickens from large and small companies were 2.056 and 1.837 log10 cfu/g, respectively, and these from breast meat (shallow) were 1.931 and 1.1693 log10 cfu/g, respectively. The mean values of total salmonella isolated from breast meat (deep) of chicken from large and small companies were 1.731 and 0 log10 cfu/g, respectively. The number of salmonella in chickens produced by large companies were significantly (P
