WHAT ARE CYANOBACTERIA?
Cyanobacteria are single celled creatures that live in
water environments. Cyanobacteria have characteristics in
common with both bacteria and algae. In warm nutrient rich
conditions free-floating cyanobacteria cells can multiply
quickly to form what are known as algal blooms. Large
numbers of Cyanobacteria can also grow as mats on river and
lake beds and these mats can sometimes detach and float to
the surface. Some cyanobacteria species produce toxins
(cyanotoxins), which pose a risk to humans and animals when
consumed in drinking water or by direct contact during
