“So if tuna fish contain mercury, is it risky to eat their meat?” “Or “How much is this amount of mercury limited to?” “Should we be concerned at this point?”

Bride, Let’s answer these questions.

Tuna has relatively higher mercury levels compared to other seafood.

So much so that, according to Food and Drug Administration (FDA) estimates, tuna is produced on average per million 0.126 to 0.689 parts of mercury Contains. In addition, some types of tuna contain more of this substance than others.

For example, canned albacore tuna, also called albacore tuna, weighs about the same as canned light tuna, such as skipjack or yellowfin tuna. 3 times more Contains mercury.

Again, except tuna, some sharks, swordfish, marlin and mackerel The reason top predators like these contain mercury is a process called bioaccumulation.

Inorganic mercury enters the natural environment through industrial pollution and is converted into the organic form methylmercury by micro-organisms in the marine ecosystem.

Small amounts of methylmercury can also occur naturally from bacteria in sediments and some wetlands. Then this chemical by small aquatic organisms is consumed and is then consumed by large predators in the food chain.

Mercury is a substance that is absorbed so quickly that it is absorbed at every level in the food chain. more metal accumulation causes. Likewise, mercury or methylmercury is so abundant in the environment that it is possible to find this substance even in tuna fish in the middle of the sea.

On the other hand, consuming large amounts of mercury for a long time can cause neurological problems.

According to the Environmental Protection Agency, symptoms of methylmercury poisoning include; vision problems, tingling sensation in hands, feet or mouth, These include lack of coordination of movements, muscle weakness, speech and hearing disorders.

But to worry about mercury poisoning, you have to consume large amounts of tuna over a long period of time. For example, according to FDA guidelines, adults can consume one serving of canned tuna two or three days per week. But more, unwanted health problems It can lead to

In short, mainly tuna Several types of fish contain mercury. Caution when consuming these fish is very important for health.
