Don’t eat these 5 types of fish

In today’s world, environmental pollution is a growing concern and one particular issue is the high levels of mercury found in our water sources. This contamination affects fish, and consequently, anyone who consumes them is at risk of mercury exposure. While people usually associate mercury exposure with industrial environments, it’s important to understand that eating certain types of fish can also contribute to mercury poisoning.

Mercury exposure through diet primarily occurs from fish that have accumulated high levels of this toxic element. Consuming fish with elevated mercury levels over time can lead to serious health issues, impacting brain and liver function, and increasing the risk of neurological disorders such as Alzheimer’s, Parkinson’s, autism, and depression.

But which fish should you be cautious about?

Catfish

Catfish, especially the larger ones, are often farmed using growth hormones to increase their size, maximizing profits. Unfortunately, this practice raises concerns about their cleanliness and potential for high mercury levels. It’s advisable to be discerning when selecting catfish for your meals.

Ocean Perch

The U.S. Food and Drug Administration (FDA) has identified ocean perch as a fish highly susceptible to mercury contamination. These fish reside near the seabed, where they can accumulate mercury that sunlight hasn’t destroyed. Ocean perch are also omnivorous, making them more vulnerable to absorbing toxins and microorganisms present in the water. Long-term consumption of ocean perch can lead to mercury poisoning, which can damage your mouth, teeth, digestive tract, and kidneys.

Catfish

Though Vietnam has opportunities to boost its economy by exporting catfish, it’s faced challenges due to mercury content. Tests conducted in the United States for substances like crystal violet and Malachite green showed concerning results, leading the U.S. to classify catfish as substandard for consumption due to high mercury levels.

Mackerel

Mackerel is well-known for being rich in omega-3, beneficial for both young children and expecting mothers. However, not all mackerel types are safe. The Atlantic mackerel is considered one of the safer options, but it’s important to educate oneself about mercury levels before consumption.

Eel

Eel is another fish that can easily get contaminated with mercury. Additionally, it tends to absorb industrial and agricultural waste from water sources. This makes them less desirable for consumption because of the potential health risks linked to mercury.
