To my knowledge, this is not the case for salmon. Whereas wild salmon is not safe to eat raw unless it has been frozen, this should not be necessary for farm-raised salmon of the highest quality.

Yeah, the FDA guidline is that all fish except for tuna must go though the freezing process, unless they are farm raised.

It doesn't have to be a long time if it's a special freezer. You can use a regular deep freezer (non-defrosting) for a longer time. I believe the protocol is something like -30F for 1 day, or -5F for 14 days.

You should probably remove your guess or provide a source. If people are seriously dumb enough to “cook” with a dishwasher, someone is probably going to also take your guess at face value.

Maybe you should provide a source for your guess that my statement is a guess, or remove it. Maybe you could Google first?

What you will find is that there are multiple sources with slightly differing times, even from reputable agencies. What I have stated is actually on the conservative side. Here's one source that is on the faster side.

That's what I call a long time, but yes, it's just a matter of personal perspective.

Also, IIRC they use a brine/vinegar solution to help kill bacteria.
