Do you prefer that your Salmon come from wild-caught sources, or that if farm raised it comes from Scotland instead of Thailand? How accurate ARE those labels at the fish counter? The Universtiy of Hawaii took a look at this recently. They were assessing the levels of mercury in fish offered for sale that were mislabeled.

Their study took measurements of mercury from fish purchased at retail seafood counters in 10 different states show the extent to which mislabeling can expose consumers to unexpectedly high levels of mercury, a harmful pollutant.

Fishery stock “substitutions”—which falsely present a fish of the same species, but from a different geographic origin—are the most dangerous mislabeling offense, according to new research by University of Hawai‘i at Mānoa scientists.
