Are scallops high in mercury?

I'm curious to know if scallops are a SAFE seafood option in terms of mercury content. As someone who values their health and the well-being of the environment, I'm always mindful of the potential risks associated with consuming certain types of fish and shellfish. Could you please clarify whether scallops contain high levels of mercury, and if so, what precautions should be taken when incorporating them into one's diet?
