| Abstract | |
Food safety has become one of the biggest concerns to public health authorities, in view of the millions of victims of foodborne diseases world spread. Face to the social and economical changes in the societies, the public health risks are arising. As a reflex, the popularity of street food commerce exposes the consumers\' health to other threats. Bento is an ancient Japanese tradition of bringing ready-to-eat meals wherever you are, which surpassed the modem way of life and is still a convenience way to have a fast meal. But face to the trading features and composition its quality is doubtful. Therefore, the aim of this study was to evaluate the nutritional and microbiological qualities of bentos sold at the oriental district, in São Paulo. Sixty samples were purchased during spring and summer seasons from 17 points of sale and they were classified according to their epidemiological risk. The macronutrients were determined and the sanitary conditions were evaluated through the research of coliform organisms, Escherichia coli, Staphylococcus aureus, Bacillus cereus and Salmonella spp. The samples composition ranged from raw fish to :full course meals. The nutritive value presented a large variation and the average proportions of macronutrients in relation to the total energy value was 16% of protein, 19% of lipids and 65% of carbohydrates. The portion energy value ranged from 136 to 885Cal. B. cereus posed the greatest percentage risk of contamination, among the pathogens. The hygienic conditions of the bentos were critical in 65% of the samples. No statistical difference was observed in the microbiological counts related to the sample collection season or its sort. In general, 73.3% of the samples were unsuitable for consumption and considering the time-temperature abuse such proportion can reach higher degrees. The consumption of bentos poses a potential health hazard, showing to be necessary greater investments in health education for every sector of the food chain, including the consumers, as an effective way of inhibiting the risks to public health.
