The aim of the study was to determine the efficacy of acidified sodium chlorite (ASC), chlorine dioxide and trisodium phosphate (TSP) in the reduction of contamination levels regarding total microbial count, coliform bacteria, Staphylococcus aureus and Salmonella Enteritidis in chicken carcasses after a decontamination process. Experimental material comprised skin sections from the neck collected from chickens on the production line. Each sample consisted of skin sections coming from three carcasses, each at approx. 20 g. Next each section was divided into two parts, one being the control and the other was the tested sample. Samples were decontaminated by immersion in solutions of analyzed antimicrobial compounds. Control samples and samples after decontamination were subjected to microbiological analysis in which total microbial count, coliform bacteria and Staphylococcus aureus were determined in accordance with the standards PN-EN ISO 4833:2004, PN-ISO 4831:1998, PN-EN-ISO 6888-1:2001 and PN-EN-ISO 6888-1:2001/A:2004, while Salmonella Enteritidis was determined according to the recommendations of the manufacturer of the Chromagar Salmonella Plus medium. An effective antibacterial effect of the applied compounds was found in the limitation of bacterial counts on chicken carcasses. The greatest reduction of total bacterial count, amounting to approx. 25%, was shown when applying acidified sodium chlorite. Trisodium phosphate was the most effective agent against coliform bacteria, reducing their number by 92%. The best antibacterial effect in relation to Staphylococcus aureus was obtained using chlorine dioxide. A 44% reduction of the count of Salmonella Enteritidis was observed for all the applied compounds. A considerable decrease in the level of microbial contamination in poultry carcasses, including pathogens, effectively enhances the standard of health safety in poultry meat.
