By  | 

Nutritionists always tell us that in order to achieve optimal health we should eat fish at least once a week. In optimal conditions, fish is really heart-healthy, protein-rich and packed with omega-3 fatty acids, but in today’s world it is also packed with contaminants and poisons and due to the poisoning of the environment, many types of fish contain very high levels of mercury and radiation, as well as some other contaminants completely unsafe for human consumption.

Read on to learn about the top 14 contaminated fish and then do your best to avoid them.

1. Swordfish


Swordfish makes for a very tasty meal and it’s popular among all fish lovers, but you shouldn’t be eating it as it contains extremely high levels of mercury – possibly the highest levels a fish of that size could contain. Swordfish naturally feed on other fish, which are these days usually highly contaminated, so it gets poisoned by its food.

Methyl mercury found in swordfish is a strong neurotoxin which can damage the nervous system of a pregnant woman’s fetus and significantly deteriorate the health of a child who eats this fish. However, mercury is dangerous for healthy adults as well and according to Natural Resources Defense Council (NRDC), once a human body ingests it, this toxin interferes with the brain and nervous system.

A study conducted in San Francisco which included 123 people and 30 types of fish found that frequent consumption of swordfish significantly increases the levels of mercury in the blood. Realizing how dangerous these levels can be, the Food and Drug Administration (FDA) and the Environmental Protection Agency (EPA) are advising people not to eat swordfish – this especially applies to young children, women who may become pregnant or already are, as well as mothers who are nursing.

According to the NDCR, high levels of mercury in the blood (mercury poisoning) can cause infertility in men and women, memory loss, vision loss, numbness of the fingers and toes and blood pressure problems.
