Pathogenic bacteria are responsible for a significant number of food poisoning in humans through infected Poultries. Our study was aimed to evaluate the effect of post-chilled washing process in a slaughterhouse and types of temperature dependent-transport vehicles on bacterial load of common food-borne pathogens; Staphylococcus aureus, Salmonella spp. and Escherichia coli of chicken carcass. One hundred and eighty fresh chicken carcasses were randomly gathered from a commercial poultry processing plant in West of Tehran After sampling in slaughterhouse, the carcass samples were taken from 3 types of vehicles, pickup, cool isolated and cool-off isolated vehicles. The mean value of the total count of whole carcasses in pickup group reached the maximum (18.63×106 ±2.82×106) and showed greater value (p<0.05) than the standard value (5×106) CFU/gr while in cool-off isolated vehicle reached the minimum (0.65×106±0.048×106) lesser in comparison to the standard. it is concluded that chicken transport by un-cooled or unusual vehicles could prepared inappropriate condition cause to integrated growth the bacteria and resulted in transmission the food borne zoonotic pathogens to humans.
