Dans la présente étude, une étude de qualité microbiologique a été réalisée afin de déterminer la présence de Salmonella et d’E. coli dans les saucisses de dinde vendues dans les supermarchés de la zone nord de Guayaquil. Il s’agit d’une étude expérimentale qualitative qui a permis de déterminer la présence de micro-organismes dans les échantillons de saucisses de dinde analysés. Les analyses ont été réalisées au laboratoire de microbiologie alimentaire de la faculté des sciences chimiques de l’université de Guayaquil de mai à août 2018. La détermination de Salmonella a été réalisée par la méthode traditionnelle en utilisant la gélose XLD (Xylose, Lysine, Désoxycholate) sélective pour Salmonella. Pour E. coli, des plaques Petrifilm AC ont été utilisées, ce qui facilite l’identification et le dénombrement de la population totale de bactéries présentes sur les produits de consommation humaine ou les surfaces. Les résultats obtenus indiquent qu’il n’y a pas de présence de Salmonella et d’E. coli dans aucun des échantillons analysés, et l’étude a également montré la présence de coliformes totaux dans les fourchettes autorisées par les normes INEN consultées.
