This study investigated the health risk of heavy metal in smoked Trachurus trachurus sold in Yenagoa, Bayelsa state, Nigeria. The fish samples were purchased from Tombia Junction market in Yenagoa metropolis, Nigeria. The samples were dry-ashed, digested and analyzed using atomic adsorption spectrometry. The daily intake and target hazard quotients were computed following standard procedure. Results showed mean manganese, copper, chromium, zinc and iron 0.865mg/kg, 0.085 mg/kg, <0.001mg/kg, 12.98mg/kg and 37.20 respectively. Manganese, iron and zinc concentration were above recommended level for fish food as specified by Food and Agricultural Organization/ World Health Organization and Median international standard.
