Shark and King Mackerel
Sharks are top on the list of fish that you may never eat. Sharks are referred to as kings of the sea, so they are high on the food chain. They are known to contain high levels of mercury and can cause various health conditions. Sharks develop slowly and they don’t give birth to many offspring. Therefore, they are at a high risk of going extinct. Sharks may also be discarded as waste by tuna fishers and swordfish.
King mackerel contains high levels of mercury and methyl mercury. It is highly dangerous for pregnant women and children. Mackerel generally is a good source of omega-3 fatty acid. However, certain types of this type of fish may contain high amounts of mercury and cause severe health conditions. The Food and Drug Administration warns children and women to stay away from king mackerel because it is known to contain high levels of mercury.
