Residents and visitors in New Zealand's Marlborough Sounds are being warned against collecting or eating any shellfish due to the presence of dangerous toxins. New Zealand Food Safety (NZFS) confirmed on July 10, 2026, that routine testing revealed unsafe levels of paralytic shellfish toxin in mussels sampled from Canoe Bay.

The public health alert is in effect for a significant portion of the Marlborough Sounds. The advisory specifically covers the area extending from Tennyson Inlet to Fitzroy Bay, urging caution for anyone who might gather shellfish from these waters.

Paralytic shellfish poisoning (PSP) is a serious illness that can occur after consuming shellfish contaminated with saxitoxins. Symptoms can range from tingling and numbness to paralysis and, in severe cases, death. NZFS conducts regular monitoring to ensure the safety of seafood consumption.
