| Objectives of this study were to investigate the process sensitivity to Campylobacter spp. and to assess the reduction efficiency of ozonation and chlorination in chilling step of the poultry process using data derived from mCCDA plating and SimPlate MPN methods. Samples of 80 were collected from 4 process steps in the processing plant (scalding, plucking, inside outside washing, and chilling). Numbers of Campylobacter spp. on mCCDA at the respective steps were 3.35, 3.20, 2.68 and 0.20 logCFU/ml, while the SimPlate MPN had 2.54, 2.48, 2.31 and 0.84 log CFU/ml, respectively. Chilling is the most sensitive process to reduce the number of bacteria on both media. Chlorination at 1.5 ppm reduced Campylobacter spp. by 97.46% and 58.62% on mCCDA and SimPlate... |
