                                While the herring is generally considered a safe, low-mercury fish, wild-caught herring from certain historically polluted areas, like the Baltic Sea, may contain higher concentrations of persistent organic pollutants such as dioxins and PCBs. Understanding what toxins are in herring, and what factors influence their presence, is key to informed seafood choices.
