IMPACT OF PATHOGENIC MICROBES OF WATER AND MOLLUSC A Mytilus galloprovincialis IN THE BUTRINTI LAKE

摘要

In Albania, the bivalve mollusk farming industry has become particularly important. The nutritional quality of mussels depends on the area and water in which they are cultivated. Therefore, the assessment of bacterial pathogens in water and mollusks that grow on it, is an indicator of quality and food safety for this product. The study is focused on the evaluation of the microbial load (E. coli, Vibrio Cholera and Vibrio parahaemolyticus) of Butrinti Lake water in southern Albania and the Mytilus gallaprovincialis mussel cultivated in this lake. For Escherichia coli, first was used medium MMGN, and was passed to the TBX Agar. For Vibrio cholera and Vibrio parahaemolyticus were used mediums, ASPW (Alkaline Saline Peptone Water), TCBS (Thiosulphate Citrate Bile Sucrose Agar), SNA 1% (Saline Nutrient Agar) and TSI. Microbiological analysis has shown that the concentration of E. coli bacteria in the Butrinti lagoon is much higher than the level considered safe for direct human consumption. Resulted that there was no presence of Vibrio cholera but there were samples with Vibrio parahaemolyticus. Since bivalve mussels are also a carrier of pathogenic bacteria, the assessment of their presence continually serves as a preventative measure to avoid risks to the consumer.
