Potential health hazards are related to the way people are exposed to the toxins:
- Swallowing water containing algae toxins may cause gastroenteritis symptoms such as vomiting, diarrhoea, fever and headache.
- Inhaling affected water droplets may cause respiratory problems and flu-like symptoms.
- Skin contact with water, including sensitive areas such as the eyes, ears, mouth and nose, may cause irritation, skin rash, flu-like symptoms, and fever.
- Eating fish and other food caught in algae-affected waters may present a health risk.
- Boiling algae-affected water will not remove algae toxins or make the water safe to drink.
Importantly, children and pets are more susceptible to the effects of toxins. Do not allow either in the water, and seek medical advice if you are concerned about their health.
