Which large, predatory oily fish are often highlighted by bodies like the FDA as requiring severe limitation due to mercury accumulation?
Answer
King Mackerel
The text specifies that the concentration of mercury varies significantly based on the size and age of the fish, leading to higher levels in larger, older predatory species. Health authorities, including the FDA, frequently name specific species that should be avoided or severely limited due to this bioaccumulation. Among the examples cited as high-mercury concerns are shark, swordfish, king mackerel, and tilefish. Conversely, fish like salmon, herring, and sardines are generally encouraged due to their lower mercury profiles.
