Objectives: Coliform and Escherichia coli are the bacterias that cause different digestive diseases in animal and human. The purpose of this study was to determine the contamination rate of the broiler carcasses to Coliform and Escherichia coli in slaughterhouse in bandarabbas. Material & Methods: Total Viable Count (TVC), Coliform count and Escherichia coli count of broiler carcasses in different stages of slaughtering process were performed by sampling from ten broiler herds. Number of twenty samples was taken by using wet and dry swabbing method, from the neck skin, in each of five stage of processing. Results & Conclusion: Coliform count, Escherichia coli count and TVC were higher after postmortem inspection and evisceration stages. Fridman statistical analysis showed the median amount of coliform count and e.coli count was significantly different between the stage of processing (p<0.05). wilcoxon statistical analysis for coliform count and E.coli count also showed significant increase between after plucking stage with other stages of processing (p 0.05). it seems performing evisceration stage manually is the cause of increasing bacterial contamination of poultry carcasses after this stage. also, increasing after post mortem inspection stage is due to mishandling and after the chiling stage caused by using contaminated ice blocks. So, it seems it is necessary paying most attention to hygiene points for reducing the bacterial contamination between the stages of slaughtering in slaughterhouses.
