Seafood safety: high throughput diagnostics for ciguatoxin risk assessment

点击翻译按钮获取中文摘要

This project aims to develop a novel, high throughput platform for rapidly assessing ciguatoxins. Species of the marine microalgae Gambierdiscus produce ciguatoxins, which accumulate in fish through marine food chains to cause the often debilitating human illness called ciguatera fish poisoning. Ciiguatera fish poisoning is a growing and substantial risk for the $2.2 billion Australian commercial fishing industry. This serious illness is increasingly impacting more southerly areas of Australia due to environmental changes. The outcomes of this project include new knowledge of the risk of ciguatoxins at Australian 'hot spot' sites, extensively field tested methods for detecting Gambierdiscus and ciguatoxins in situ and key data to inform policy to safeguard the seafood industry and consumers.
