This work aimed at assessing the presence of total aflatoxins (AFs) and aflatoxin B-1 (AFB(1)) in fish farmed in two Cameroonian localities and the possible origin of that contamination through analysis of fish feeds as well as water and mud collected from the fish farming ponds. Four fish species (kanga, tilapia, catfish, and carp) were collected from two fish farming sites (Mfou and Batie). Mud and water from the farming ponds of the different species and the fish feeds used in these sites were also collected. The samples (34) were analyzed for their levels of AFs and AFB(1) using the competitive ELISA method. The results obtained showed that all fish tissue contained AFs and AFB(1). A level of AFs higher than the threshold value recommended by the FDA (20 ppb) was observed in catfish (31:38 +/- 0:29 ppb). AFs and AFB(1) were presented in fish feeds as well as in muds collected from the farming ponds. Catfish was the fish species which mostly bioaccumulated aflatoxins in their tissue. This study presents the state of art on the mycotoxin contamination of fish farmed in some Cameroonian localities and suggests that attention should be paid to the quality of ingredients used to feed fish.
