Unsafe Biotoxin Levels Detected in Bay of Plenty Shellfish

Authorities in New Zealand have raised concerns over unsafe levels of a deadly biotoxin found in shellfish along the Bay of Plenty coastline, prompting a public health warning. The New Zealand Food Safety Agency has issued a caution, urging residents to avoid collecting or consuming shellfish from the coastal area between Mount Maunganui and Whakatāne.

Health Risks and Public Advisory

According to Vincent Arbuckle, deputy director-general of the New Zealand Food Safety Agency, routine testing revealed that levels of paralytic shellfish poisoning (PSP) toxin had exceeded the safe limit. This toxin poses serious risks to human health and is not neutralized by cooking. As a result, the agency has strongly advised against the consumption of shellfish from this area.

Cause of the Toxin Outbreak

The presence of the toxin is linked to an algal bloom currently spreading in the region. These blooms produce dangerous toxins that accumulate in the gut and flesh of shellfish, making them hazardous to consume. It is important to note that this warning applies only to shellfish collected recreationally. Commercially harvested shellfish sold in shops and supermarkets are subject to rigorous safety monitoring and are deemed safe for consumption.

Symptoms of Paralytic Shellfish Poisoning

Individuals who consume contaminated shellfish may experience a range of symptoms, including numbness, tingling, difficulty swallowing or breathing, dizziness, nausea, and vomiting. In more severe cases, the toxin can lead to paralysis and respiratory failure, which can be life-threatening.

Immediate Action Required

Anyone who has consumed shellfish from the affected area and is experiencing symptoms should contact Healthline immediately or seek medical attention. Prompt treatment is crucial in managing the effects of PSP and preventing severe complications.

Public health officials continue to monitor the situation closely. Residents are advised to refrain from collecting shellfish between Mount Maunganui and Whakatāne until further notice and to rely on commercially sourced shellfish for consumption.
