Their meat can be contaminated with metals, chemicals, pesticides and various parasites.. Species of harmful fish described in his book “Killer Fish: How Seafood Endangers Your Health” Dr. Brian Clement.

List of harmful fish that is better not to eat:.

1) Pangasius.

Pangasius is grown in the waters of the Mekong River, one of the dirtiest rivers on the planet.. The surroundings of the river during the Vietnam War were thoroughly poisoned by chemicals. Also, untreated sewage is dumped into this river and all kinds of waste is dumped.. Even when frozen, fish use the same water.. In addition, in order to accelerate the growth of pangasius, chemical additives are used. In its meat, an increased content of anaerobic and aerobic microorganisms is often found, E. coli.

2) Wild Chilean Sea Bass.

The Chilean sea bass has a very high mercury content, so it can be consumed no more than twice a month. This fish is also threatened by a too rapid reduction in numbers, because sea bass is in great demand and global stocks are declining.. Stay away from sea bass caught in the Crozet Islands, Prince Edward Islands, Mariana Islands, and Chile. There is the most infected fish.

3) Tile.

The meat of this fish also has a high concentration of mercury. It can be eaten no more than once a month by adults. Better fish caught in the Mid Atlantic.

4) Bigheads.

This fish lives up to 100 years, but it is quite small.. In addition, her meat contains a large amount of mercury..

5) Shark.

A shark is a predator, and mercury is absorbed by small aquatic plants and animals that large fish eat.. According to the Environmental Protection Fund, half of the sharks dying each year die by-catch.

6) King mackerel (mackerel).

Mackerel has one of the highest mercury scores. It’s better not to risk it and not eat it at all. In order not to take risks, it is better to take the Atlantic mackerel.

7) Cod.

Better not to use wild-caught cod. An alternative in this case would be cod grown in aquaculture recycling systems.

8) Swordfish.

This fish is contraindicated for children, adults can have one serving per month. It's all about mercury again. In addition, most of this fish is caught using long lines, a fishing method that also makes endangered creatures online, including turtles, sharks and seabirds.

9) White tuna (escolar, butter).

The meat of this fish is very tasty, but excessive consumption can cause karyorrhea, a form of diarrhea. Escolar contains the non-digestible fatty substance hempotoxin, which gives its meat a juicy buttery taste and texture.

10) Bluefin Tuna.

Most types of tuna contain mercury in varying amounts.. Bluefin tuna has the highest mercury level, and it also has the lowest environmental ratings.

11) Red Snapper.

Tilapia is often sold under it.. Farm-grown tilapia has very low levels of beneficial omega-3 fatty acids and very high levels of omega-6 fatty acids. This combination can be potentially dangerous for people with heart disease, arthritis, asthma and other allergic and autoimmune diseases..

Better give preference to black cod or striped bass.

12) Mahi Mahi.

This fish can cause histamine poisoning.. If the fish is not properly cooled, then the bacteria begin to destroy the amino acid histidine in the fish, forming a histamine that can cause a disease similar to an allergic reaction.
