Unless you're buying from a fish market or catching it yourself, the majority of seafood is flash frozen on the ships that catch them. If you grab a salmon fillet out of the freezer section of your grocery store, odds are it's flash frozen, and thus, safe to eat raw. Fresh caught salmon is similarly safe to eat raw provided it's consumed or brought below 40f in sufficient time.

Raw seafood is recommended to be stored at room temperature for under two hours if you're intending to consume it. Tap water is usually heated to 120-140f in the US. And the drying cycle is normally 110-170. A typical rinse and dry cycle is 30-90 minutes. With the increased thermal conductivity of water and metal foil, the rinse cycle should rapidly increase the temperature of the fish and the dry cycle, aided by the increased ambient humidity of the rinse, will easily maintain that for long enough to raise the internal temperature of the fish to, at the very least, the usual 125.

The only way this could not be the case is in an extreme outlier. Say a washer with a 30 minute total rinse/dry, with tap water that does not exceed 120f, and a dry cycle that does not exceed 110, and with fresh caught fish that has been sitting on the counter for a couple of hours before being placed in the washer. It's very unlikely for this to be the case.

I'm not saying anyone should do it, it seems pointless and weird. But it's technically possible and should be reasonably safe
