Etude de la qualité hygiénique de la Daurade Royale « Sparus aurata » (linnaeus, 1758) élevée à Mostaganem

Abstract

Hygiene is a determining factor in the health quality of fish. As it is a highly weatherable matrix, an objective assessment of its hygienic quality is essential for the operators in the sector but also for the inspection services. The objective of our experimental study is to evaluate the microbial load status of farmed fish, marketed in the wilaya of Mostaganem. To do this, microbiological analyses were carried out on the Royal Sea Bream (Sparus aurata) (Linnaeus, 1758) sold in three different locations in the city of Mostaganem (Castor, Mostaganem port street and Salamander). Total Aerobic Mesophilic Flora (FMAT), Total Coliforms, Thermo-tolerant Coliforms, E.coli, Coagulase + Staphylococci suspected pathogens, and Salmonella have been researched. The microbiological results obtained show a total absence of faecal coliforms, E. coli and salmonella in all samples analysed. However, the presence of three other germs was revealed. These are Staphylococcus coagulase +, total coliforms and total aerobic mesophilic flora. The presence of 30° germs (FAMT) was reported in all samples analysed but at rates that do not exceed the standards in force. The same was reported for total coliforms, whereas for coagulase + Staphylococcus, these germs were revealed only to Castor with a very high and unrecognizable rate, making this collection of quality fish unsatisfactory with the non-compliance with the standards by comparing it with the other two samples from the port street of Mostaganem and that of Salamandre which showed satisfactory quality.
