A survey is being conducted in the Wairoa region of New Zealand to understand the potential human health risks from toxins accumulating in tuna and other wild-caught species, particularly in Whakakī Lake. The project is a collaboration between the Whakakī Lake Trust, the New Zealand Food Safety Science and Research Centre, and Cawthron Institute, funded by the government’s Vision Mātauranga research fund since 2022. The survey will help researchers understand tuna consumption patterns and whether the concentrations of toxins in tuna pose a risk to people’s health. The project also aims to collect information on other wild-caught aquatic species consumed in the region. The survey is confidential and voluntary, and data will not be used to track tuna harvesting or abundance.
