What does blue-green algae look like?

Blue-green algae – also known as cyanobacteria – are microscopic bacteria found in freshwater lakes, streams and ponds but they clump together and can rise to the surface and form green flakes or brownish dots.

When the algae blooms, it can give look like a blue-green scum has appeared on the surface of the water.

It can affect the appearance and quality of the water and some varieties give off a musty or grassy odour.

Not all blue-green algae blooms and scums are toxic, but you can’t tell just by looking at them.

Is it dangerous to dogs and people?

Only some blue-green algae is toxic both to dogs and humans, most are not toxic.

People can become ill after swimming or water skiing in lakes with it.

Only in severe cases will people suffer stomach pains, vomiting, skin rashes and diarrhoea.

Pets can die from drinking contaminated water as it triggers liver failure.

There is no antidote to the toxins and immediate veterinary care is needed.
