Commercially sold refreshments are stored in juice dispensers that, if improperly cleaned, will be a means of contamination, therefore making the consumer vulnerable to foodborne diseases. Assessment of the microbiological quality of food provides information that enable to evaluate, in terms of processing, storage and distribution, the useful life of foodsand risks to public health. Given the current consumption of fruit refreshments and the assumed severity of contaminated food ingestion, this study aimed to evaluate the microbiological quality of juices stored in dispensers and marketed in the cities of Barra Mansa and Volta Redonda-RJ. We collected seven samples of refreshments, five of cashew juice and two of orange juice, in 250 ml sterile packages, from commercial establishments such as coffee shops and bakeries. For microbiological analyzes, we investigated for the presence of Salmonella sp. and fecal coliforms; and for the physicochemical analyzes, determinations of titratable acidity and pH were performed. Two of the seven samples were not in conformity with the norms established by the current legislation regarding the presence of coliforms at 45º C or thermotolerant. The results of Salmonella sp. analyses indicated that all samples were in accordance with the applicable legal standards, all samples (100%) of cashew juice analyzed for titratable acidity were in accordance with the law, but , this was not observed for the orange juice sample (50%). It was concluded that 29% (2) of the analyzed samples were unsuitable for consumption and may pose a health risk to consumers.
