Assessment of Microbiological Contamination of Marine Ecosystems : Can we Continue to Limit Ourselves to the Analysis of Fecal Parameters for the Assessment of the Coastal Ecosystems Quality?
Keywords:
Salmonella, Escherichia coli, Agadir, Morocco, MusselsAbstract
This study reports the relationship between the level of faecal cantamination and the prevalence of salmonella in the coastal and shellfish areas of the Agadir coast (south of Morocco), 801 samples of mussel, sea water, and marine sediment collected for48 months from six site along the Moroccan Atlantic coast between Essaouira and Sidi Ifni.Two methods were used for this study:(AFNOR NF EN ISO 6579 V08-013) to detect the presence of salmonella spp, and the most probable number method (ISO/TS 16649-3 standard) to detect E. coli the overall prevalence of salmonella spp.is 7.1%. The number of E.Coli was between 18/100g and 28.103/100g of flesh and Liquid intervals .This study indicates the potential health risk associated with the presence of these bacteria and their relationship in the assessment of microbiological contamination of the marine environment in this populated region of southern Morocco where shellfish production and maritime tourism are important to thelocal and national economy.
