Blue green algae is a type of bacteria that can be found in fresh or saltwater. It can have a range of beneficial effects, such as helping to improve water quality, but it can also have some unwanted side effects. These include reduced oxygen levels in the water, changes in the pH levels, and the release of toxins which can cause skin and respiratory irritation in humans. In more extreme cases, blue green algae can cause liver damage, vomiting, and diarrhoea. To reduce the risk of experiencing these side effects, it is important to avoid contact with water where blue green algae is present, and to ensure that it is not overabundant in the environment.

Is blue-green algae harmful to humans?

Blue-green algae, also known as cyanobacteria, can produce toxins that can be harmful to humans and animals. Ingesting large amounts of these toxins can cause nausea, vomiting, and diarrhea, as well as liver and neurological damage. The toxins can also be absorbed through the skin, leading to rashes, skin irritation, and other allergic reactions. It is important to avoid contact with water containing blue-green algae, and if you do come into contact with it, to wash the affected area thoroughly.

How do you get sick from blue-green algae?

You can get sick from blue-green algae if you come into contact with it or if you eat contaminated food or water. The toxins produced by blue-green algae can cause a variety of symptoms, including skin irritation, respiratory distress, vomiting, and diarrhea. Ingesting large amounts of the toxin can be fatal. To avoid getting sick from blue-green algae, it is important to avoid swimming or playing in water with a blue-green algae bloom, and to drink only bottled or boiled water.
