In the article, "Study finds mislabeling issues in Washington, D.C.," SeafoodSource incorrectly reported that a Chilean sea bass sample was mislabeled because it was called "Patagonian toothfish". In the United States, it is legal for Patagonian toothfish to be marketed as Chilean seabass. Antarctic toothfish - the species that the George Washington University researchers identified in one restaurant sample - is a sister species to the Chilean seabass. Both Antarctic toothfish and Patagonian toothfish may be called Chilean sea bass.
According to the researchers' peer-reviewed journal article, "One of the three 'Chilean seabass' we tested was identified as Antarctic toothfish, the sister species to the Chilean sea bass, also known as the 'Patagonian toothfish.' Of our 12 samples from six restaurants, we found that four menu items, one 'Chilean Sea bass,' two 'Tuna' and one 'Rock Shrimp', were potentially mislabeled, albeit with species that are either closely related or typically considered acceptable for the menu listing."
SeafoodSource regrets the error.
