"Although nearly 50 percent of the grocery stores visited in Boston sold mislabeled fish, the cod-loving city was tied with Seattle where salmon is king, as having the lowest deception rates. Lucky consumers in those seaports can expect only one in five fish samples to be wrongly labeled."
"In New York City, EVERY sushi venue sold mislabeled fish.
In Washington D.C., EVERY snapper sample was mislabeled
In South Florida, King mackerel, a fish on the FDA’s DO NOT EAT list for pregnant women and other at risk groups due to high mercury, was sold as the far less innocuous grouper."
I'm surprised that in South Florida they could away with selling mackerel as grouper. Grouper is a great tasting fish and I refer to it as the steak of fish. People in Florida love their grouper and I'm surprised that people there would be fooled. What's next? Somebody trying to pass off crayfish as lobster in Maine?
In most cases on the west coast there is no real red snapper,it is all mis labeled. When I was a kid my mom bought Red Snapper whenever is was flown in. Red Snapper has a strong iodine flavor. Pacific Rock fish does not.
If it glows in the dark don't eat it. Tuna in 12 months time can cross the Pacific from Japan to California several times.
, it is not as bad:
