In this study we analysed the microflora of chicken feces during the fattening period and the flora on the carcasses at the main slaughter processing steps, using traditional cultural microbiological techniques. There was no relation between composition and concentration of contaminant (enteric) bacteria in feces and on eviscerated carcasses. No significant changes of concentrations of Enterobacteriaceae, E. coli, Enterococci, Staphylococci, Lactobacilli and Pseudomonas were observed after scalding, defeathering and evisceration, whereas during chilling the average counts decreased for >= 0.9 log for all bacterial groups except Staphylococci. None of these bacterial groups was found suitable as an indicator for the contamination of the carcass with bacteria originating from feces, feathers or skin.
