Why does shark meat have high levels of mercury?
Shark meat contains high levels of mercury, largely due to the unique feeding habits and life cycles of sharks. As apex predators, sharks at the top of the marine food chain feed on other fish, including those who have accumulated mercury through their diets, as well as smaller marine animals such as fish, squid, and crustaceans. Mercury is a naturally occurring toxin that enters the ocean through industrial pollution and atmospheric deposition, and once there, it is ingested by microorganisms, such as plankton and bacteria, which are then consumed by smaller fish. These fish in turn accumulate mercury in their tissues as they feed on the contaminated organisms. Sharks, being at the pinnacle of the marine food chain, feed on these mercury-rich animals, which subsequently builds up in their own bodies, making shark meat one of the most contaminated sources of mercury in the ocean. As a result, consuming shark meat regularly can have serious health implications due to the potential neurological and developmental effects of mercury exposure.
Can the mercury in shark meat be harmful?
While sharks are fascinating creatures, you might be wondering about the safety of consuming their meat.

As apex predators, sharks have a higher concentration of mercury in their tissues compared to smaller fish. Consuming large amounts of shark meat can lead to mercury poisoning, which can cause neurological problems, especially in vulnerable populations like pregnant women, nursing mothers, and young children. To minimize your exposure to mercury, consider limiting your shark consumption and opting for smaller, lower-mercury fish options. Additionally, always choose shark meat sourced from reputable sellers who adhere to sustainable fishing practices.
Does cooking shark meat reduce mercury levels?
Cooking shark meat is a common practice, but does it truly reduce mercury concentrations? Unfortunately, the answer is no. Mercury is a persistent toxin that binds to the muscle tissues of sharks, making it nearly impossible to eliminate through cooking. According to the FDA, mercury vapors are not broken down or destroyed during cooking, grilling, or frying process. In fact, cooking shark meat can even increase mercury concentrations in certain cases, as the mercury is released from the proteins and becomes more readily available for absorption. For instance, a study published in the Journal of Food Science found that cooking shark meat at high temperatures (above 160°C) can lead to the formation of methylmercury, a more toxic form of mercury. To minimize mercury intake, it’s essential to choose sharks with lower mercury levels, such as dogfish or small species like spiny dogfish. If you’re concerned about mercury exposure, consider opting for alternative seafood options with lower mercury concentrations, like salmon or sardines.
