King Mackerel: The Hidden Threat Consuming More People Than You Know While king mackerel is celebrated in coastal cuisine for its rich flavor and nutritional benefits, a lesser-known truth is growing: this powerful predator may pose a hidden health risk to consumers—especially vulnerable populations. Often overlooked in public awareness, king mackerel contains high levels of mercury, making it one of the larger concerns for frequent seafood eaters. Understanding this hidden threat could help safeguard your health and inform safer seafood choices. ### What Is King Mackerel, and Why Should You Care?
