Aspectos socioeconômicos e qualidade dos molucos bivalves através do monitoramento microbiológico e genético

Abstract

This study aimed to define the profile of fishermen and shellfish collectors woman in São Francisco do Conde, as well as analyze the microbiological quality of oysters (Crassostrea sp.), fresh mussels and mussels processed (Mytella guyanensis) extracted estuary of the Subaé river and marketed in the municipal market and genetic characterization of mangrove oysters. 31 people were interviewed, 29% women and 71% men, most aged between 30 to 50 years, low level of education, proper housing with electricity, water, sewage and trash public collection. The public health system, hospital and / or health center is used by 41.9% and 93.5% of respondents. Cases of diarrhea were reported in 10% of adults and 14% of children. Concern for environmental preservation was observed in 100% of respondents, while 97% see the need to conduct environmental projects in the city rivers. Molluscs analyzed showed high microbial 3 8 -1 2 7 - load values of coliforms at 35ºC of 10 to >10 NMP.g , 45 ºC of 10 to 10 NMP.g 1 5 -1 , Enterococcus sp. <3,0 to >10 NMP.g and presence of Escherichia coli (64%) and Salmonella sp. In the molecular study observed high genetic variability among oyster individuals, favoring the activity of oyster farming in the region. Molluscs collected presented low microbiological quality and can serve as a vehicle for outbreaks. This is alarming since the activity of shellfish serves as a source of income for the population. The high genetic variability of subjects is a decisive factor in the adaptation of individuals to habitat.
