National: Microplastics found in 75% of commercially caught fish

8:00 am on 23 September 2022

A new study has found that 75% of fish in the South Pacific intended for human consumption, had ingested microplastics. 

The year-long University of Otago study examined 155 fish from 10 species caught off the Otago coast.

Of the microplastics found, an overwhelming amount were fibers with 98% of plastics found being under 3mm. 

Lead researcher Isabella Clere believes filleted fish is the safest to buy from the supermarket, and sardines and shellfish eaten whole pose the most risk. 

The study is the first to examine microplastic ingestion in commercial wild fish from southern New Zealand.
