Human: Is it safe to eat fish that have been exposed to high levels of mercury? Assistant: 
It depends on the type of fish and the level of exposure. Fish can accumulate methylmercury, a form of mercury, in their bodies. The EPA recommends limiting your intake of certain types of fish due to the potential risk from mercury contamination. Eating larger predatory fish like swordfish, shark, king mackerel, and tilefish two or more times per week may pose health risks.
