The Hidden Danger in Our Waters
Imagine your family pet suddenly falling sick after a seemingly harmless swim in the local lake. The culprit could be lurking undetected: cyanotoxins. These powerful toxins, created by harmful algal blooms, present a growing threat to our water sources. But what exactly are they, and how can you protect yourself, your family and your pets?

What Are Cyanotoxins?
Cyanotoxins, potent poisons produced by certain cyanobacteria (commonly known as blue-green algae), pose significant dangers. While not all cyanobacterial blooms are toxic, visual identification of hazardous blooms is unreliable. Several types of cyanotoxins, including microcystins and anatoxins, can cause severe harm to the liver, nervous system, and skin.
The Serious Health Risks of Cyanotoxin Exposure
The dangers associated with these toxins are substantial. Short-term exposure can lead to skin irritation, nausea, and vomiting. Long-term exposure poses risks of liver damage, neurological issues, and potential links to cancer. Children, pets, and those with pre-existing health conditions are particularly vulnerable. Furthermore, cyanotoxins not only harm human health but also devastate aquatic life and local economies. Therefore, understanding these potential risks is essential.
How to Identify and Protect Against Harmful Algal Blooms

Identifying and proactively protecting against blooms is essential. While visual signs such as green scum and unusual odours may suggest potential blooms, they are not conclusive. Reliable water testing, often available through your local council, is essential for accurate assessment. To safeguard yourself and others, avoid swimming in affected areas, keep pets away, and ensure proper drinking water treatment. If you suspect cyanotoxin exposure, seek immediate medical attention and report the incident. In New Zealand, high levels of cyanotoxins are a notifiable event, prompting public health responses
