Store frozen fish frequently makes a world journey before it ends up at your supermarket. It might be caught near England, processed in China, and stored in some pacific island cold storage and eventually to your plate. If it was farmed fish from Russia or China who knows what those fish were being fed. Eating fresh and local fish is an extremely good idea if you don’t have faith in 3rd world food safety. Make sure to buy California garlic and not the Chinese stuff that is grown in toxic soil and peeled by prison labor.
