Mercury in Fish

Author: mom_to_one, 10 23rd, 2012

The most common source of mercury poisoning comes from eating fish that have been living in polluted waters. Larger fish that primarily feed on other fish wind up having higher mercury levels because their food sources already have concentrated mercury in their bodies, leading the larger fish to have an even greater build-up of this mercury.

When humans eventually eat the fish – often from the biggest fish like swordfish, tuna, or sharks – the mercury is transferred into the body of the human, which can sometimes be at toxic levels, leading to serious mercury poisoning. This can be a very serious problem, particularly for pregnant women, nursing mothers, and young children.
