In 2012 the European Food Safety Authority (EFSA) reported on chemical contaminants they found in the food of over 20 European countries. Certain ethnic groups, as well as young children, are more likely to suffer the effects of methyl mercury poisoning.

In Ghana, the local population traditionally consumes large quantities of fish, leading to potentially dangerous amounts of mercury in the bloodstream. In addition to enacting legislation controlling the mercury levels in potential pollutants, Japan has directly influenced the environment by issuing regulations setting acceptable levels of environmental mercury pollution. In the United States, Wallace gathered data that indicated 16.9% of women who self-identify as Native American, Asian, Pacific Islander, or multiracial exceed the recommended reference dose of mercury.

This article evaluates the nutritional. Catla catlaCatla catla 4. [30] Another study of marketplace fish caught in waters surrounding Southern Italy showed that, undoubtedly, greater fish weight leads to additional mercury found in fish body tissues. The type and degree of symptoms exhibited depend upon the individual toxin, the dose, and the method and duration of exposure. While it is difficult to estimate the exact extent of mercury re-emission, it is an important field of study. This process is known as bioaccumulation (6).

Most of the participants (95%) had blood levels of mercury in the safe zoneunder 5.8 micrograms per liter (g/L). [47][48] Airborne mercury is dissolved in the oceans, where microorganisms convert waterborne mercury into methyl mercury, which enters the food chain and is stored in fish tissue. [62] These findings suggest that choosing to consume a type of tuna that has a higher natural fat content may help reduce the amount of mercury intake, compared to consuming tuna with a low fat content.

However, some fish may contain mercury or other harmful chemicals at sufficiently high levels to be a concern. Froese, Rainer; Pauly, Daniel (eds.) Mercury rapidly increases in concentration as is moves up the food chain and can concentrate to high levels in large predatory fish in certain environmental conditions (such as acidic lakes). Allow it to stand for 1-2 hours . These fishes have a high protein content and have low fat.
