The aim of this work was to evaluate the contamination of chicken meat sold in Rabat and Salé by Listeria monocytogenes (L. monocytogenes). This pathogen was isolated from 300 samples of chicken meat collected in supermarkets and in traditional slaughterhouses during the period from June 2011 to December 2012. The prevalence of L. monocytogenes found from the 300 samples analyzed was 3.66% (n=11). Statistical analysis showed that there was no significant difference between the different sampling locations (p1 = 0.4424; 1 = p2 and p3 = 0.5598) in regards to contamination of the chicken meat by L. monocytogenes even if these sites have a big difference in respect of the good hygiene practices.

Abstract: (french)
L’objectif de ce travail était de contribuer à l’évaluation de la contamination de la viande de poulet commercialisée dans 10 grandes surfaces (GS), 10 tueries traditionnelles situées au niveau des différents quartiers (TTQ) de la ville de Rabat et 10 tueries traditionnelles situées au niveau d’un bidonville à la ville de Salé (TTB) par Listeria monocytogenes (L. monocytogenes). De même, montrer statistiquement s’il y a une différence significative entre ces sites de prélèvement de point de vu contamination par ledit pathogène. Ce germe pathogène a été isolé à partir de 300 échantillons de viande de poulet prélevés durant la période allant de juin 2011 à décembre 2012. La prévalence de L. monocytogenes trouvée dans les 300 échantillons analysés était 3,66 % (n = 11). Tandis que, la prévalence trouvée dans les 100 échantillons prélevés au niveau des sites de catégorie 1 (GS) était 5% (n = 5), celle trouvée au niveau des sites de catégorie 2 (TTQ) était 2% (n = 2) et celle trouvée au niveau des sites de catégorie 3 (TTB) était 4% (n = 4). L’analyse statistique a montré qu’il n’y a pas de différence significative entre les différents sites de prélèvement (p1=0,4424 ; p2=1 et p3=0,5598) de point de vue contamination de la viande de poulet par L. monocytogenes, même si ces sites présentent une grande différence pour ce qui est respect des bonnes pratiques d’hygiène.
