Abstract :

Fish caught in contaminated environments constitute a health hazard for consumers, since fish, like other fishery products, are capable of transmitting microbial and parasitic infections to humans. The aim of this study was to identify the parasites present in the fish Distichodus maculatus Boulenger, 1898 and Schilbe grenfelli Boulenger, 1900 caught in the Malebo Pool (Congo River). The analyses focused on microscopic observations of samples of Congo River water and D. maculatus and S. grenfelli fish. The results show that the Congo River water and the digestive tracts and gills of D. maculatus and S. grenfelli fish are infested with four species of parasites (Strongyloides stercoralis, Ascaris lumbricoides, Entamoeba coli and Trichurus trichiura). Of the parasite species identified, A. lumbricoides (15 positive cases), E. coli (5 positive cases) and S. stercoralis (3 positive cases) were the most frequently observed in the gills and digestive tracts of D. maculatus and S. grenfelli fish. In order to reduce the parasite load and reduce the risk of infestation for humans and aquatic ecosystems, the political and administrative authorities are called upon to take appropriate measures to limit the pressure on aquatic ecosystems and their resources, including fish. Cooking fresh fish thoroughly before eating is the best way to avoid parasites.
