Blue Green Algae (Cyanobacteria)

What is Blue Green Algae

Cyanobacteria (also known as blue-green algae) are microscopic bacteria found in freshwater lakes, streams and ponds. They can produce toxins  that affect people, livestock and pets (including cats and dogs) that swim in and drink from the algae contaminated water. They give the water a blue green appearance which, is also usually accompanied by clumps of algae on the surface (however these are not always present). It is around all year round however, it is worse in the summer months.

Any pet that has been near a water source which contains this can be at risk to it.
