RESUMO
Summary The composition of the microbiota of the Aro cheese marketed in the municipality of Teotitlan de Flores Magon, Oaxaca, Mexico, was determined, quantifying the aerobic mesophilic bacteria, psychrophilic bacteria, total coliforms, Escherichia coli, Staphylococcus aureus, Salmonella, Enterococcus, Streptococcus, lactic acid bacteria, moulds and yeasts. The results showed that the Aro cheese contained pathogenic and spoilage microorganisms as well as those of industrial importance. None of the samples analysed complied with NOM-243-SSA1-2010. Thus this cheese could transmit foodborne illnesses, due to its high content of E. coli, Staphylococcus aureus and Salmonella. The shelf life of the cheese could also be affected causing economic losses to the producers. On the other hand, microorganisms of industrial importance can be obtained (Lactobacillus and Streptococcus). It is necessary to implement quality assurance systems to guarantee the production of innocuous cheeses.
