Public awareness of the dangers of blue-green algae (cyanobacteria) needs to be raised.  This can occur in inland waterways and estuaries, in fresh, brackish and sea water either in suspension or in clumps or as a bloom, floating on the water surface and can resemble blue/green paint.

Not all occurrences of blue green algae produce toxins but it is believed that 50% do, so it is safer to avoid all blue green algae.  These toxins are lethal to wild animals, farm animals and domestic animals.  In humans, rashes and illnesses occur, in some cases the illnesses are severe.

Do not allow children or pets near waterways which have a blue or green scum.  If in doubt stay away.
