Remember...Real Salmon don't eat pellets, or steroids, or colourants, or antibiotics.
Steroids?? Please elaborate.
Wild salmon eat lot's of antibiotics, along with loads of contaminants ... sadly they are part of the food chain nowadays. Whatever antibiotics you, your neighbor, or your mother uses goes down the toilet and ends up in.. yeah you guessed it, the ocean and eventually in wild salmon.
Know any lady using birth control pills? Guess where that estrogen and other hormones end up ... yeah, right again, in that wild coho you ate last night.
