Abstract

This study focuses on the bacteriological quality of bivalve molluscs (Mytilus galloprovincialis & Chamelea galina) of the Mediterranean coast of east Morocco.A total of 109 samples have been analyzed by the method of the enumeration of Escherichia coli β-glucuronidase positive and the search and identification of the different types of total floras such that the Enterobacteriaceae (ENT), the Mesophilic Flora Total Aerobic (FMAT), the Flora Moderate Halophile (FHM), Flora Producer of Hydrogen Sulphide (FHS) and Flora Psychrotroph (FP). The results of the enumeration of Escherichia coli β-glucuronidase positive by 100g CLI denote values which present no risk of contamination according to the circular 1508 /12 of the Minister of Agriculture and Fisheries on health conditions for the production and placing on the market of live bivalve molluscs.The results of research and identification of different types of total floras show a bacterial diversity of bivalve molluscs of the studies regions, with a dominance of Staphylococcus, Streptococcaceae and Acinetobacter.
