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.

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.
