Public warnings about toxic shellfish
We test shellfish and seawater for toxic algae every week from popular shellfish gathering areas around New Zealand. If the shellfish are not safe to eat, we issue public health warnings and put up signs at affected beaches.
If you get sick after eating shellfish
If someone gets sick after eating shellfish, make sure you:
- phone Healthline for advice on 0800 61 11 16, or get medical help immediately
- advise your nearest public health unit
- keep any leftover shellfish in case it can be tested.
Safety of commercially sold shellfish
The warnings on this page are only for recreational shellfish that people can collect themselves. The warnings do not apply to shellfish that you can buy from shops or supermarkets, or shellfish for export.
We have strict water and flesh monitoring programmes for commercial shellfish to ensure it's safe to eat. If commercial shellfish become toxic, the shellfish cannot be harvested or sold, and the growing areas are closed.
