The mercury (methylmercury) found in humans is 80%-90% the result of consuming shellfish and/or fish, especially tuna (3). If animals (such as poultry and farmed fish) are fed contaminated feed in the form of fish meal, the mercury tends to accumulate in their fat tissue and then when the fat from that animal is consumed by the human, it can create a source of exposure for the human. This barrier prevents neurotoxins from entering most of the brain, except for some regions (1). All humans are exposed to some level of mercury. Answers from doctors on sources of mercury exposure. There are many ways a person can be exposed to mercury. The consumption of fish is by far the most significant source of ingestion-related mercury exposure in humans, although plants and livestock also contain mercury due to bioconcentration of organic mercury from seawater, freshwater, marine and lacustrine sediments, soils, and atmosphere, and due to biomagnificationby ingesting other mercury-containing organisms.
