Santos RM. Evaluation of the sanitary quality of fish commercialized in Municipal Market at the city Sao Paulo. [dissertation]. Sao Paulo (BR): Faculdade de Saude Publica da Universidade de Sao Paulo; 2006. Introduction. Due to the increase consumption of raw fish, observed mainly in the Japanese culinary, and the fact of the fish can carry a number of microorganism capable of producing food borne disease, this research was delineated. Objective. To evaluate the sanitary conditions of collection sites and the sanitary quality of fishes sold in the Municipal Market in Sao Paulo city with the purpose to be consumed raw and compare the data with the current legislation. Methods. Observation of the environment through 10 predetermined items. Microbiological enumeration of thermo-tolerant coliform bacteria, Staphylococcus aureus, presence of Escherichia coli, Salmonella in 25g and Vibrio sp, according to APHA in 20 fish samples. Results. Punctuation obtained varied from 2 to 8 points representing attendance to the 10 selected items. From the 20 samples, 2 (10%) presented thermo-tolerant coliform and 1 (5%) S. aureus above the established limits. Three samples presented strain characteristic in the biochemical test and positive serum, for Salmonella sp, however after the selection for the PCR none was considered positive. E. coli was obtained from two samples. The presence of potentially pathogenic Vibrio sp (V. fluvialis and V. Metschnikovii) was observed in 3 fish samples. Conclusion. Despite the good infrastructure in the majority of fish shop observed, it was possible to identify a deficiency in the adoption of good manufacturing practices. The traditional methods of identification of Salmonella spp, can result in false-positives. The existence of potentially pathogenic Vibrio species, which are not contemplated by the current legislation, may represent a risk to the public health.
