Is there a reason why tuna is specifically called out as an exception?
I would imagine that tuna, being near the top of the food chain, would accumulate an awful lot of things in their bodies, not just mercury as commonly feared.
- arcticbull 3y agoWeird eh? My understanding is tuna don't get parasites as often. I read about it here. [1] > Exempted from the FDA's freezing requirements are, as Herron mentions, large species of tuna—deemed safe based on the frequency with which they are eaten in raw form and the infrequency of related, documented parasitic infection—as well as aquacultured fish, like salmon, given verification that the feed it's raised on is parasite-free. > To meet FDA guidelines, every other type of fish must be frozen to those temperatures, even if the table does not indicate that it carries a parasite risk, because it "may have a parasite hazard that has not been identified if these fish are not customarily consumed raw or undercooked."

- simiones 3y agoBased on this, it sounds more like tuna is the only fish we know is mostly parasite-free, not the only fish that is mostly parasite-free. Perhaps most fish is actually parasite-free, but since we don't have enough evidence of that, the FDA is not going to allow selling it unfrozen.
