I recently became aware of the risk of getting sick from ciguatera by eating fish. A forum search shows a number of posts about this but most seem to be in the context of eating fish that you catch.
My question is, am I generally safe by only eating fish from restaurants? I know that cooking doesn't remove the risk and that it's safest to not eat reef fish but when I'm looking at a menu, I don't necessarily know which fish are reef fish and which aren't. Are the restaurants only serving non-reef fish or otherwise able to be trusted to not poison me (setting aside baseline risks of getting sick from eating anything)?
How much of an issue is this if I'm not eating fish that I catch?
