I just watch a segment on Dr Oz the other day on shrimp. They said one should only eat shrimp that simply states on the bag the word shrimp and only eat shrimp from the US as other countries lack proper regulations.

I love to eat breaded shrimp and bought some a couple months back from our local large retailer as you could buy maybe three, four shrimp to go with a steak. It was rather good baked but I just couldn't move past the fact it was from Ecuador and kept envisioning it being raised in dirty tanks or containing some weird worm from being captured in dirty waters.
