A new seafood-labeling scheme went into effect yesterday across the U.S. The regulations require that retailers label fish and shellfish with the country of origin and whether they were raised on a farm or caught in the wild. The labels may be put directly on packaging or on signs in the display cases.

Proponents say the labels satisfy a consumer’s basic “right to know” about products before purchasing them. Greens should be pleased because the labels will make it easier for consumers to choose seafood from the safest (read: low mercury and POPs) and most sustainable sources. The Monterey Bay Aquarium’s Seafood Watch resources can help with those delicious decisions as well. Browse their regional lists of seafood broken down into three categories: best choices, good alternatives, and those to avoid. You can also print your own pocket-size guide. Bon appetit!
