One hundred and eight of fish samples were randomly gathered from fish farms, also 24 water samples obtained from pools separately in twophases. All samples in order to in order to isolate bacteria including salmonellae, Escherichia coli and citrobacter freundii were examined by selective and purified culture media. Results of this study showed that neither of fish nor water samples was contaminated to salmonella, but contamination of fishes to Escherichia coli and citrobacter were 20.3 and 7.4 percent, respectively. Water contamination to Escherichia coli was 66.7 % but there were not any contamination to citrobacter and salmonellae in water samples. As the result of this study showed, Rainbow trout fishes in this area are not considered such as a source for human salmonellosis; however there are some risks that other enteric bacteria such as Escherichia coli may involve people by this food stuff.
