“Fresh, never frozen sashimi does not exist in the US.”
“Fresh, never frozen sashimi does not exist in the US because of FDA regulations. Raw fish (except tuna) is illegal to serve if it has not been flash frozen. Master sushi chefs will all say that it is necessary to age fish in deep freeze for tender, great tasting sushi.” – Redditor HBunchesOo
In a 2004 interview with The New York Times, George Hoskin, director of the FDA’s Office of Seafood, confirmed that all fish intended to be eaten raw must be frozen before sale to kill parasites. Tuna is the exception because of its “exceptionally clean flesh.”
