Nutritionists usually include fish among the foods that a balanced diet should contain. Although it is true that there are many benefits, currently it is better to avoid them or eat them in small amounts. Unfortunately, due to the environmental damage and the impact of industrial companies; the fish are contaminated. Below are 10 fish that are contaminated with mercury and radiation.

Contaminated fish you shouldn’t eat

Consuming fish is vital to obtaining ample omega-3 fatty acids, and certain fish can serve as potent sources. However, due to emissions from fossil fuels and heavy metals such as mercury, mercury poisoning from contaminated shellfish is a real threat and can have devastating effects, especially on the developing fetus and adults as well.

In addition to the negative consequences on health, certain fish are in danger of extinction, so their consumption could accelerate the extinction process.

1- Shark

Sharks are at the top of the food chain. Due to this, they feed on any type of fish and the mercury found in them begins to lodge in these species. This means that any type of shark should be avoided because for all of them, the main food is fish.

2- Swordfish

Swordfish is one of the fish that is considered to contain a large percentage of mercury. Due to its large size, its diet is based on other types of smaller fish that are contaminated. This has led to high levels of methylmercury in their bodies.

This neurotoxin has been found to primarily affect pregnant women. Well, it manages to pass the placenta very easily, fatally damaging the baby’s nervous system.

3- King Mackerel

Although this predator is found in the ocean, it is a fish that contains large amounts of mercury. This is because large industries come to incinerate their waste or materials. In turn, these are dispersed through the air culminating in the waters. Which means that such residues accumulate in the King mackerel.

4- Tilefish

This white meat fish is highly sought after in the various restaurants that offer seafood. However, specialists warn that there are some species of fish that have a high degree of mercury. As there are many variants and the highly contaminated ones are unknown, it is suggested to avoid all of them. Children and women especially, for being the most affected.

5- Albacore tuna or tuna steaks

The tuna is moderately contaminated by this toxicity. In view of this, it is recommended to consume it only in small portions. The type of tuna to be consumed must be taken into account ; since yellowfin tuna tends to be much more toxic than white.

6- Spanish mackerel

This fish is another that is highly contaminated due to its large size. Being a migratory species, it moves from the Spanish Atlantic to the Gulf of Mexico and then to Florida. On his travels he consumes a large amount of mercury, which his body accumulates. Due to their experience on the coasts, they become very easily contaminated.

7- Orange Roughy

These are fish that have a very long and durable lifespan. It is said that they can live up to 150 years. This longevity is a point against them, because in all those years they accumulate toxins.

8- Blue fish

It is on the list because it is a species that becomes contaminated due to storms and chemical and industrial discharges. They become loaded with both mercury and other powerful toxins, such as pesticides.

9- Chilean sea bass

In addition to being a fish that has the highest levels of mercury, it is one of the endangered species. If fishing for this aquatic animal is not put aside, the probability of existence is 5 years.

10- Pacific Ocean Perch

This is another fish that should be avoided entirely. Its high mercury content is potentially harmful to human health. This toxic element not only accumulates in fish, but also in the body of humans.
