1. The objective of this study was to evaluate the effects of dry ice decontamination on equipment and carcase surfaces in a poultry slaughterhouse and to present an effective alternative method to the conventional decontamination processes. 2. Appreciable reductions occurred in total aerobic mesophilic bacterial counts of surface swab samples treated with dry ice (maximum difference 3.92 log CFU/100 cm(2)). 3. After dry ice treatment, Listeria spp. were detected on surfaces of pluckers and chiller cylinders whereas Salmonella spp. were totally inhibited. 4. A dry ice spraying application was more effective than a dry ice immersing application on total aerobic mesophilic bacteria and yeast and mould counts on poultry carcases. 5. Dry ice treatment has advantages over conventional processes. Unlike other decontamination techniques, there are no residues, so no need to wash off chemical residues from surfaces as is removes contaminants effortlessly and is environmentally friendly. 6. Dry ice blasting of production equipment can reduce the microbial load and has potential for use in the poultry industry.
