Moluscos bivalves: Organismos Bioindicadores da Qualidade Microbiológica das Águas: Uma Revisão

Abstract

The sustainable exploration of marine resources is a challenge to everybody worried with the quality of human life. The cultivation of marine organisms like bivalve mollusks (oysters and clams) is an alternative food source and also an option to the survival of coastal communities while the consumption of grown up in market like happens food in south and southeast regions of Brazil. However, the domestic sewer discharges into water reservoir like rivers and ocean are the pollution source more frequent on aquatic environments endanger the fish product quality. Oysters are filter organisms able to ingest suspension particles including high concentrations of pathogenic microorganisms. On the other hand, the frequent custom of eat this food in natura, without cooking can cause foodborne toxinfection mainly in immune compromised individuals. So, it is necessary to adopt preventive steps to control of pathogenic agents circulation as the selection of mollusks catch areas, depuration after catch, control of water and algae that are food for oysters and the adequate handling and store of this food.
