Sumario:Cheeses and sausages are ready-to-eat foods, and the products prepared by artisanal process are susceptible to microbial contamination. Few studies on the quality of foods from different Brazilian regions have been done. In this context, this study aimed at evaluating the microbiological quality of 32 cheese and 13 sausages samples purchased from artisanal food stores or producers markets located in the metropolitan areas of 10 capital cities of Brazilian states. Microbiological analyses were performed to determine the counts of microbial contamination indicators, including Escherichia coli and coagulase-positive staphylococci, as well as for evaluating the presence of Listeria monocytogenes and Salmonella spp. using bacteriological methods. E. coli was detected in 50.0 % of samples, coagulase-positive staphylococci in 34.4 %, and Salmonella spp. in 6.3 % of cheese samples. In fermented sausage samples, coagulase-positive staphylococci were isolated from 23.1 % samples and Salmonella spp. from 7.7 %. According to the Brazilian Sanitary Legislation, 63.0 % of cheese samples and 23.0 % of artisanal fermented sausage samples from the metropolitan areas of 10 Brazilian capital cities were unsuitable for consumption, indicating the importance of conducting the close monitoring of these foods and the application of the effective measures for preventing food-borne outbreaks.
