What Saltwater Fish Can You Not Eat: A Guide To Safe Seafood Choices

The puffer fish, belonging to the family Tetraodontidae, are renowned as the most toxic fish globally, earning them a reputation as the second most poisonous vertebrate, trailing behind the golden dart frog. These fish species possess a potent neurotoxin known as tetrodotoxin, concentrated in their liver, skin, and certain organs. Consumption of improperly prepared puffer fish can lead to severe poisoning and even death. Therefore, it is crucial to exercise extreme caution when handling and consuming these fish, and it is advised to seek out expertly trained chefs who are skilled in their safe preparation.

Which fish contain the highest levels of mercury? The mercury content in fish varies, and it tends to be more concentrated in species that are long-lived and positioned higher up the food chain. Some examples of such fish include marlin, tuna, shark, swordfish, king mackerel, and tilefish. These fish accumulate more mercury due to their longer lifespan and consumption of smaller fish that also carry mercury. So, when choosing fish to eat, it’s important to be aware of these factors to make healthier seafood choices and reduce your mercury intake.
