It`s no secret that tuna fish is beneficial for you and your health. Many diets are based on tuna, so seafood in general is considered to be rather healthy.
Nowadays with all the contamination of the waters, I don`t think we should be hooked on tuna`s meat. Especially, if we go through the Internet and do a little research. It doesn`t seem bright for Bluefin tuna.
Consumers are exposed on a radioactive Bluefin tuna. This news didn`t come as a surprise regarding the fact that a massive disaster took over Fukushima and therefore affected the sea life in the Pacific Ocean.
The story behind the radiation…
For those of you unfamiliar with the Fukushima disaster on March 2011, a massive earthquake shook the core of Japan, causing an enormous damage to the country and its surroundings. Now, after five years, we are still feeling and discussing the side effects of all of this.
The earthquake and tsunami caused series of events, such as explosions and meltdowns. The result of all of this was enormous amounts of radioactive material in the air as well as in the Pacific Ocean, and nowadays radioactive material is still leaking into the ocean from the plant.
All of these catastrophic events triggered a bigger problem, contamination of the waters of the Pacific Ocean and therefore endangering the sea life in it. Studies have shown that every tuna fish (Bluefin tuna) examined after the catastrophe have proven to contain radioactive isotopes, but we still do not know all of the effects of this poisoning.
A great amount of this radioactive material is in the form of cesium. Cesium 134 is usually connected with the Fukushima disaster and it has a half- life of two years, whereas Cesium 137 dates since 1950 with a half- life of 30 years.
Is the radiation affecting sea life?
This is for sure alarming, not because studies have shown toxins in Bluefin tuna, but also because this means that every little organism in the Pacific Ocean is affected by it.
This radioactive cesium that floats in the Pacific Ocean, causes tuna fish in particular to consume it and therefore intake toxins and radioactive materials which may put this fish on the list of dangerous foods.
A study done by the Stanford University and Stony Brook University examined the radioactive levels in the Pacific Ocean and therefore the poisonous levels in Bluefin tuna, caught off the shores of California and they shockingly discovered that every fish tested contained radioactive material.
Tuna fish can easily swallow the toxic materials and accumulate them.Also they can become affected by this radioactive material just by swimming in contaminated waters or consuming contaminated pray. During time and as they grow larger and larger, they got rid of some of the radiation but not fully.
Moreover, this research has been done early after the catastrophic disaster, meaning that for five years fish have been exposed on this radiation and people were consuming radiated Bluefin tuna.
Tuna is maturity happens after five years, so plenty of tuna fish have been living their entire lives with radioactive materials and not only was the Japanese area affected by it, but it affected the whole Pacific Ocean due to the fact that Bluefin tuna is a migratory fish and travels long distance, from shore to shore.
Knowing this fact, that Bluefin tuna transmits radiation, we should also be cautious about migratory species such as sharks, seabirds and turtles.
Is Bluefin tuna harmful in any way?
Bluefin tuna is red meat can be notably expensive, especially in Japanese sushi restaurants when it can get up to $24 per piece. However, is this tuna an exclusive meal or a dangerous meal?
People are probably mostly worried about the risk of cancer, because let`s face it, Japanese people are much more exposed on the radiation than Americans will ever be, but still we cannot turn heads on this. Bluefin tuna has gone from exclusive to notorious.
Even though nothing has been proven about risk of cancer or any other diseases, yet we cannot be sure or safe. The word is out, I don`t think that anyone will have a Bluefin tuna without a stomach flip, better safe than sorry they say.It should be noted that the radiation is taken into consideration, and it is also stated that radiation is below safety limits by government regulations, meaning that the radiation does not cause some enormous changes in people.
We are exposed on radiation from our food, soil and rock and the rates of cesium 134 and cesium 137 are less than radioactive potassium which occurs naturally in fish.
