Tuna, like many other larger predatory fish such as shark, king mackerel, tilefish and swordfish, contains high levels of mercury. White albacore contains the most mercury, while other options, such as chunk light tuna, are looked at as better alternatives.
Mercury, often derived from human industrial activity such as coal-fired electricity generation, finds its way into our streams and rivers, which ultimately feed into our oceans. High levels of mercury in the human body can lead to mercury poisoning, extremely detrimental for not only women and children, but grown men. Overdose can lead to neurological or heart problems.
