Abstract :
Listeria spp. Has been isolated from poultry , red meat products and fish in many countries around the world. Listeria monocytogenes has been isolated from water and ice used for relating freshness of food. Chiller water could possibly increase the microbial contamination of poultry carcasses in slaughter-house. Therefore, the aim of this study was to investigate the effects of water chiller on Listeria monocytogenes contamination of poultry carcasses before and after chilling process in four industrial slaughter house of western Azarbaijan province was investigated. 180 poultry carcasses from 4 industerial slaughter house in western azarbaijan was investigated for Listeria monocytogenes befor and after chilling process using the modified Canadian version. All of the isolated belongs to the serogroup 1 and 4. Paired – samples T test indicated significant difference (P<0.05) between the contamination levels before and after chilling process.
