If we’re talking food safety, I don’t believe those sea lice are any danger to a consumer. Don’t they just invade the gills of the fish?

The lice from the farmed fish devastate the wild salmon populations, so ecologically they are awful.

That to me is a pretty clear reason to avoid farmed salmon.
