摘要： In Mozambique, as in other developing countries, the sale of street food is a source of income for thousands of unemployed families. However, the safety of these types of foods is a serious problem, given their frequent association with food-borne outbreaks. The aim of this study was to assess the microbiological quality and safety of street food sold in the main streets and informal markets of Maputo, the capital of Mozambique. From 83 different vendors selling different types of foods, 83 samples of ready-to-eat (RTE) street food were analyzed. Mesophiles, Escherichia coli and total coliforms were used as quality and hygiene indicators. Listeria monocytogenes, Salmonella and coagulase positive staphylococci were used as food safety indicators. High proportions of unsatisfactory food samples were found in both traditional hot (76.7%) and cold (75%) foods. L. monocytogenes and Salmonella were tested negative in this survey. However, when coagulase positive staphylococci was used as a food safety indicator, approximately 25% (23/83) of the food samples analyzed were classified as unsatisfactory/potentially hazardous. These results, showing that street food sold in Maputo clearly requires adequate sanitary conditions for its preparation and sale, contribute to the development of good manufacturing practices (GMP) for street food in Maputo, Mozambique. This is the first report on the microbiological quality and safety of street food in Mozambique.
