I'm sure many readers have read alarming reports about unsafe and unsanitary practices in fish farms across Asia. I've long since stopped buying any farmed seafood from that part of the world.

If you want to know why you should never buy Asian or Far Eastern farmed seafood, watch it all the way through.
Having watched that, please read the four articles linked above: then check every package of seafood in the supermarket before you buy it, and reject any from fish farms in the Far East! The same goes for restaurants serving seafood. Demand to know where it came from before you order it!
