We really can't tell if anything is truly organic anymore. Stores try as much as they can to assure us of organic stuff but that's not that reliable. For example, the young coconuts from Thailand, for examples, we know they are farm-raised with chemicals but the American whole foods stores sell them as organic drinks just because they are natural-looking.
The venison we get from the wild here, we think they are natural. But do you know what deer eat? Corns and soy beans from chemical farms around their environments. Our fish from the lakes and rivers around the Midwest? Find a non-polluted lake or river or soil and we might have truly natural, organic meats and veggies. But otherwise, those factories that have polluted our airs and waters have contaminated the drinks and breaths of our food animals.
Oceans aren't that clean anymore. So, those in Cal and New Jersey or Florida that catch from the seas get some that aren't all natural or clean.
At most, we know that if we catch or pick things from the wild, we might a lesser chance of eating chemicals. Nothing that would be 100% pure.
Hmmmm, need to pay more attention to the fine print. But still, many types of food in this country are filled with chemicals of some sorts from fruits to veggies to fish, to meats, to so many things. Is ocean caught truly means ocean caught and organic truly means organics anymore. The best way to know is produce your own food - get your own fish, grow your own veggies, raised your own livestock, etc..
Some folks in CA catch their own pampanos, I hear. I wonder if they have to take a boat into the ocean or can just hook a fishing line by one of those piers...
