Some Fish Contain High Levels Of Mercury

While not all fish are affected, many species contain high levels of mercury, posing serious risks to human health. Swordfish, for example, are among the worst offenders because they absorb significant amounts of mercury from their prey. But they’re not alone—other saltwater fish with longer lifespans, like sharks and certain types of tuna, also tend to accumulate mercury. Even freshwater fish like bass can sometimes have elevated levels

So, how can you stay informed? Most state and federal agencies provide warnings on their websites, and state wildlife agencies often issue notifications when they detect higher mercury levels in local fish populations. Did you know that mercury exposure can affect the nervous system, especially in pregnant women and young children? To minimize risks, consider choosing smaller, shorter-lived fish like salmon or sardines, which typically have lower mercury levels. Always check local advisories to make safer seafood choices.
