This work has been done to assess how the street-juices, sold by the moved street- vendor, can be of a possible source for pathogenic microorganisms. Evaluation of the microbiological quality of forty-three juices samples, included in four types of juices, as well as ten washing water samples, was done using three different microbiological examination methods including classic selective media, chromogenic media, as well as rapid food-system kits. The results indicated that populations of the total bacterial count ranged from 102 to 106/ ml while the average counts of mould and yeast in positive samples were 103 / ml. Fifty-percent of the examined samples were found to be contaminated with Staphylococcus aureus, 40% were positive for the presence of both Listeria monocytogenes, Yersinia enterocolitica, Bacillus cereus, and Salmonella typhimurium however 30% of the investigated juice samples were positive for the presence of Escherichia coli 0157:H7. It seems that this contamination is mainly due to poor quality of the used water as well as poor hygienic conditions applied during preparation and serving of the drink. These results may help to clarify the epidemiology of the diseases in the country and draw the attention to issue hygienic regulations for those mobile street-vendors in order to ensure safe street-vended juices.
