The meat is 100%. I’m not about to promise that if you spend your time noshing on the livers you won’t end up feeling miserable from time to time. I’ve eaten thousands of the damn things (they’re small), and a few million pounds get ate every year. I’ve actively checked, and never found an account of anyone being poisoned.
@nungesser maybe he’s using “toxin” to mean the parts of the fish that straight kill you? As opposed to those that just make your bits go fizzy?
