Abstract

This study aimed to determine the prevalence Listeria monocytogenes in raw chicken meat samples at hypermarkets and wet markets Chicken drumsticks breasts and thighs were randomly selected The most probable number IMPN) PCR method was used to quantify the I_ monocytogenes in the samples Listeria monocytogenes was detected in 20% of the samples Occurrence of L monocytogenes was highest in breast (42 03%) followed by drumstick (1127%) and thigh (7 14%) Samples from hypermarkets showed higher occurrence (2511%) of L monocytogenes compared with wet markets (14 29%) The density of L monocytogenes found in samples ranged from <3 0 to 16 firiPN g 1 The presence of L monocytogenes in raw chicken meat is unwanted but unpreventable Thus further research on the processing method to reduce and eliminate this kind of bacteria in chicken meat before consumption is necessary The presence of L monocytogenes in chicken samples suggests the importance of this pathogen in chicken Thus more study is needed to find ways to eliminate this pathogen from poultry. 2012 Poultry Science Association Inc
