concentration in the different brands of canned fish analyzed could be attributed to the fact that some fish are older than others. The low levels could be that the waters in which the fish are obtained have not yet been polluted significantly with mercury. Only few data are available for comparison in Ghana (Agorku & Voegborlo,2005). Among the brands of canned mackerel analyzed for mercury, all are in tomato sauce except Golden country which is in oil sauce. All the tuna canned fish are in oil sauce. For sardine brands, Lasco, Ohene, B.B, Swallow brand A1, Talisha and Geisha are in tomato sauce while the rest are in oil sauce. The age, source of fish and size of fish could contribute to the levels of mercury in the fish. With the exception of Bobo, Sankofa, Rising star, Star kist and Ohema all the canned fish are imported. The highest mercury
concentration was obtained in one of the local brands, Nampa tuna. This means that the canned fish consumed in Ghana both imported and local do not contribute significantly to the body
burden.
