Mercury in Fish: What You Need to Know
You can obtain health benefits from fish, but mercury exists as a toxic heavy metal in certain types that harm the nervous system. Mostly, mercury enters fish by being present in the water they swim in. When mercury is released by industry, mines, and burning fossil fuels, it ends up in oceans, rivers, and lakes. Bacteria in water can turn mercury into methylmercury, which builds up in the bodies of little water creatures.
Eating these organisms puts mercury into fish, and the larger, hunting varieties up the food chain tend to have more of it over time. Fish containing high mercury levels need limited consumption, and pregnant women together with children must strictly avoid them.
