Ten most toxic fish

Food & Water Watch just released its 2010 Smart Seafood Guide.

Why it's worth checking out: While some guides only address human health issues (like mercury) and environmental problems (like overfishing), Food & Water Watch also considers seafood's socioeconomic impact. "For example, lobster is a a key part of the economy up in Maine," says Marianne Cufone, director of Food & Water Watch's fish program. "Knowing that fact is really important to some consumers." The guide is also searchable by taste and texture, which makes it easy to use for recipe substitutions.
