Introduction: Exposure to mercury (Hg) by consumption of fish is a recent health concern. So, it is important to evaluate the health risks related to canned fish consumption. The purpose of this study was to investigate the potential health risk based on Hg concentration in people who consumed canned fish with a probabilistic approach in Isfahan City, the central province in Iran.
Materials and Methods: In this study, 20 popular brands of canned fish prepared in Iran and other countries were selected and analyzed for Hg concentration with atomic absorption spectrometer. The results were compared with the European Communities and JECFA guidelines. Then, a probabilistic method with Monte-Carlo simulation was used to assessment the Provisional Tolerable Daily Intake (PTDI) and the Hazard Quotient (HQ) for consumers in Isfahan City.
Results: The average Hg concentrations in samples were 0.251 ± 0.204 and 0.189 ± 0.152 µg/g in canned fish of Iran and other countries, respectively. The Hg level was found below the guideline limit for European Communities and JECFA. The estimated PTDI was 0.037 µg person/day and HQ was 0.074.
Conclusion: The results indicated that canned fish available in the markets of Iran did not have a health risk for adults. Moreover, canned fish consumption has a possible influence on the risk estimate and its risk should be assessed  for vulnerable groups.
