Ciguatera poisoning and confirmation of ciguatoxins in fish imported into New Zealand

N Z Med J. 2021 Jun 4;134(1536):100-104.

Abstract

Ciguatera poisoning has caused illnesses in New Zealand through the consumption of contaminated reef fish imported from Pacific Islands. In May 2020 five people became ill and one was hospitalised following the consumption of Fiji Kawakawa (camouflage grouper; Epinephelus polyphekadion). The fish was purchased in New Zealand but imported from Fiji. The meal remnants were analysed for ciguatoxins, the causative compounds of ciguatera poisoning, and showed the presence of the three main toxic fish metabolites. Other fish tested from the same shipment did not contain detectable levels of ciguatoxins, indicating they were likely not toxic.
