CNN has been reporting that about 1/3 of seafood products are mislabeled. How nice is that! I don't know if they can really fake you out on lobster, though. I know it is expensive on the Maine Coast and that is where it comes from....for the most part. Only kind I ever wanted. I don't eat it anymore.
Imitation is disgusting. They soak cheap fish in lobster water and then add a ton of sugars in various forms to it along with other bits of miscellaneous chemicals. Better off buying plain fish and season it to your tastes.
