Scombroid-type poisoning induced by the ingestion of smoked kahawai.N Z Med J. 1975 May 28; 81(540):476-7.NZ
Three incidents of presumptive scombroid poisoning were reported in the Wellington area in 1973. Two of these cases were attributed to canned mackerel and the third to smoked kahawai. The marked similarity of the symptoms of the kahawai poisoning to those of the other two outbreaks of scombroid fish poisoning and the relief following anti-histamine therapy suggests that the poisoning arose from a similar source. Analysis of the extracts from the smoked kahawai revealed an abnormally high level of histamine and the presence of an unknown toxin. The unknown substance resembled saurine, the toxin that has been incriminated in scromboid poisoning, thus suggesting that scombroid intoxication may not be confined to fish belonging to the sub-order Scombroidei.
