No presente trabalho foi efectuado um estudo de qualidade microbiológica para determinar a presença de Salmonella e E. coli em enchidos de peru comercializados em supermercados da zona norte de Guayaquil. O estudo foi de carácter experimental qualitativo, o que permitiu determinar a presença de microrganismos nas amostras de enchidos de peru analisadas. As análises foram realizadas no Laboratório de Microbiologia Alimentar da Faculdade de Ciências Químicas da Universidade de Guayaquil, de maio a agosto de 2018. A determinação de Salmonella foi realizada pelo método tradicional utilizando ágar XLD (Xilose, Lisina, Desoxicolato) seletivo para Salmonella. Para E. coli, foram utilizadas placas Petrifilm AC, que facilitam a identificação e enumeração da população total de bactérias que existem em produtos ou superfícies de consumo humano. Os resultados obtidos indicaram que não há presença de Salmonella e E. coli em nenhuma das amostras analisadas, e o estudo também mostrou a presença de coliformes totais dentro dos intervalos permitidos pelas Normas INEN consultadas.
