What are the potential hazards of toxic algae?

 Cyanobacteria (also known as “blue-green algae” are a kind of algae which can produce toxins and are often found in lakes with high nutrient concentrations. Human exposure to these algae can lead to skin irritation, allergic reactions, gastrointestinal symptoms and respiratory problems. Pets and livestock are more likely to drink large quantities of lake water, potentially resulting in illness and/or death. Current research is investigating a potential link between algal toxins and human illnesses such as Alzheimer’s.
