There is a need to limit or reduce human pathogenic bacteria where wild food is gathered, with shellfish able to promote dissemination of antibiotic resistance. These were the findings of a survey of Escherichia coli (E. coli) and antibiotic resistance in aquatic foods and water in North Canterbury. Antibioticresistant bacteria were found on watercress (Nasturtium officinale) and cockles (Austrovenus stutchburyi). Greenshell/lip mussels (Perna canaliculus) kept in a tank with environmentally relevant concentrations of E. coli were colonised to levels considered unsafe for human consumption within 24 hours. Measurement of horizontal gene transfer between bacteria within the mussels showed that transmission frequency of plasmid RP4 was significantly higher in mussels than in water alone.
Canterbury researchers and Kai Tahu are leading the way in terms of protecting wai and for the wellbeing of people, and vice versa. Importantly they don’t blame the kai collection but instead focus on strategies to reduce harm to the water, the kai, matauranga Māori (traditional collection) and us.
