Carnivorous cows and vegetarian salmon....

Salmon raised in ocean feedlots, the main source of supply for American consumers, contain such high levels of PCBs, dioxins and other probable cancer-causing chemicals that people should not eat it more than once a month, according to a large-scale study to be reported Friday in the journal Science.

Read all the way to the end of this article and you'll see that the industries who brought you "mad-cow disease" by feeding rendered beef to cattle are now searching for ways to turn carnivorous salmon into vegetarians.

While I think it's a worthy goal to lower dangerously high levels of contaminants in food (the result of feeding processed small fish to farmed salmon), I can't help but worry that turning carnivores into vegetarians could create unforeseen problems in the same way that turning cows into cannibals did.

Among other things this article fails to mention is that farmed salmon are also fed pellets made from rendered beef, chicken, lamb, etc.
