ABSTRACT
The present work aims at evaluating the microbiological quality of the common horse mackerel Trachurus trachurus sold in the markets of the city of Man (Côte d’Ivoire). Total Aerobic Mesophilic Flora, Escherichia coli, Staphylococcus sp and Salmonella sp were the main germs sought in the samples analyzed. The microbiological analysis was performed by the decimal dilution technique. A total of 45 samples were used. These analyses show an acceptable microbiological quality for the total aerobic mesophilic flora. On the other hand, the microbiological quality of the Escherichia coli contamination was not satisfactory for all the samples analyzed (5.04.103 ± 0.74 and 1.12.105 ± 1.1 CFU/g). The contamination rates found in the samples from the three markets are worrying especially with the very significant presence of Salmonella sp and Staphylococcus sp respectively in the large market of Man (1.27.103 ± 1.27 CFU/g), in the Caca sport market (1.9.103 ± 1.9 CFU/g) and the Doyagouiné market (5.83.103 ± 5.83 CFU/g). These results highlighted the existence of a potential health risk associated with the consumption of horse mackerel from these different markets.
Keywords: Microbiological quality, Escherichia coli, Staphylococcus sp, Salmonella sp, Trachurus trachurus.
