The bacterial microbiota found in live fish is directly related to the microbiota of the environmente, in the words, the microorganisms present in their body surface, gills, gastrointestinal tract and muscle are related to the same environment in which it is inserted. Fish naturally have a wide range of bacteria, which may also be commonly found in the water. However, the bacteria of fecal origin, such as E.coli and Enterococci, are not common inhabitants of the intestinal flora of fish, being his presence linked to contamination by human feces or other warm-blooded animals in the water capture. Thus, the monitoring of the microbiological quality of the water and the fish caught for human consumption, it is necessary, since they can cause harm to human health, causing public health problems. The objective of this study was to evaluate the microbiological quality of fish (Eugerres brasilianus, Curvier 1830) and waters of the estuary of the River Itanhaém, SP (Brazil). Three bacteria were used to assess the microbiological quality of water and fish, two of human fecal origin, Escherichia coli and Enterococci, and a source not fecal, Staphylococcus aureus, all obtained by membrane filtration. The fish were evaluated for their gills and muscle. The results showed that during the entire period of the study, the waters of the river Itanhaém presented within the limits set by legislation CONAMA resolution 357/05, however the use of E.coli, proved to be insufficient to assess the quality of the water, since the density of Enterococci was high throughout the study in all points analyzed. The analysis of fish, were found high concentrations for the three bacteria used, with the gills presenting with greater number in relation to the muscle. According to the RDC 12/05, the fish were evaluated during the study were unfit for consumption. In the proximity of the ETE-Anchieta, located to the left boarder of the river, the bacteria S.aureus was more ...
