Review Study on the Concentration of Heavy Metals in Canned Tuna

Abstract

Canned tuna is a popular seafood product consumed worldwide, but concerns have been raised about the potential contamination of heavy metals such as mercury, lead, and cadmium. This review aims to synthesize the current knowledge on the concentration of heavy metals in canned tuna, their sources, analytical methods used for detection, and the potential health implications for consumers. A comprehensive literature search was conducted, and studies from various regions were analyzed to provide a global perspective on the issue. The findings indicate that while some canned tuna products contain heavy metals within acceptable limits, there are instances where concentrations exceed regulatory standards, particularly for mercury. The review also highlights the need for continued monitoring and regulation to ensure the safety of canned tuna for human consumption.
