7 Most Contaminated Fish You Should Avoid Eating

It is said that fish and seafood are a very good source of protein, minerals, vitamins and other nutrients. Fatty fish is a great source of omega-3 fatty acids that maintain good health. These facts are established and impossible to deny.

However, nowadays the environmental pollution makes our food contaminated. In a polluted river or sea fish is contaminated, and polluted soil cannot provide healthy grains, fruits or vegetables. Many fish are currently packed with mercury and radioactive elements. Actually, all fish contains some level of mercury. Your mission is to avoid the following top 7 contaminated fish that should not be eaten:

1. Imported Catfish
The catfish that is caught at the local lake is different from the species of catfish we are going to talk about. We are talking about imported catfish. Approximately 90% of the fish that is brought to the USA come from Vietnam. In Vietnam they use a lot of antibiotics to grow catfish. Most of them have been banned for use in the states. In the USA you can find two types of imported catfish – Swai and Basa, which could hardly be called catfish. This means that both Swai and Basa are not inspected as thoroughly as the other imported species.

2. Tilefish
This species of fish comes from a very wide family called Malacanthidae. The Environmental Protection Agency makes no distinction between them. Next time you hear that tilefish is unhealthy to eat, skip all varieties. Tilefish should not be given to anyone, especially pregnant women and children. Atlantic tilefish is said to be one of the safest varieties, but you should still avoid eating it unless you are 100% sure the species that you put in your mouth is safe. If not, exclude it from your menu.

3. Orange Roughy
Orange roughy is a member of the slimehead family. There are a lot of people who find the flesh of this fish delicious. Another interesting fact is that this fish can live as long as 150 years. This sound amazing and you might first think that eating this fish will make you close to being immortal as well. Well, unfortunately, the longer the fish lives the more mercury it absorbs. Old fish are full of toxins that poison your whole system and ruin your health. Orange roughy prefer to live in cold waters, so they can be caught in abundance in Australia, New Zealand, South Africa, the Eastern Pacific off Chile and a couple of other locations.

4. Blue Fish
This is another tricky species. Blue fish is rich in protein yet not fatty. It would make a great diet food, but the bad news is that blue fish besides mercury includes pesticides, PCBs and other harmful toxins. Agricultural chemicals that are brought to the water make this fish dangerous to eat. The fish eat algae and bacteria that may contain natural toxins.

5. Pacific Ocean Perch
Mercury accumulates in both fish and human body. Whenever you eat fish some certain amount if mercury (and, in some instances, quite significant) gets into your body. Mercury is a poisonous substance. If you know what food chain is, you will easily understand how mercury accumulates in fish. There are plenty of controlled studies that have been carried out for market production of a required species. It appears that mercury found in fish comes from plankton that fish eat. The smaller species of fish is then eaten by the larger species. Along with it, the larger fish gets the mercury accumulated in the smaller fish and so on. The more of smaller fish the larger species eat, the more mercury it contains in the flesh.

6. King Mackerel
Avoid eating king mackerel. Do not trust experts who are trying to convince you that mackerel is safe to eat. The truth is that this fish is full of mercury. If you eat it very often, this dangerous poisonous metal builds up in your body. According to Robert G. Brooks, the secretary of the Florida Department of Health, believes that it is absolutely impossible to get enough mercury from mackerel simply because the fish is caught far out in the ocean. What worries researchers is that pollutants can be spread through the air coming from industrial sources and then end up in the ocean.

7. American Eel
Yellow eel, silver eel or, also known as American eel, this fish is found in sushi bars and restaurants, as a rule. This species has been included in our list of contaminated list because of the high levels of PCB’s and mercury it contains. One of the worst things is besides suffering from pollution, this delicious fish is suffering from overfishing. A better alternative would be squid caught either in the Atlantic or in the Pacific. Both of these species taste wonderful and contain no poison. Do some research and you will find out why mercury is harmful – it impairs brain development and nervous system. It is especially dangerous for young children, infants and pregnant women.
