It does not. It asserts that Norwegian salmon as a food product does not pose a risk to consumers regarding parasites. It doesn't even talk about pharmaceutical use, chemical traces in the flesh or effects on the environment.
I'm not saying that this salmon poses health risks to consumers. But the Norwegian aquaculture industry does use a lot of pharmaceuticals in the open sea water. And the high density contributes to a high propensity for ectoparasites. Both of these things pose an environmental hazard. (I'm a Veterinarian by the way...)
I most want to point out that Norwegian farmed salmon isn't as glorious as it was stated. I'd like to add that this is a predatory species and needs to be fed mostly fish protein to grow profitably. This in turn means the food for the farmed salmon is usually fished out of the sea, too. This is certainly not sustainable and will hopefully be replaced by insect protein (soy doesn't work). But it needs regulatory action, as it is more expensive than harming the ocean...
