Algae naturally occur in inland waters such as rivers, streams and lakes and during long periods of warm weather, it can multiply and form blooms.

Blue-green algae or cyanobacteria – a type of blooming algae – can produce toxins harmful to both humans and animals.

These toxins can be dangerous for animals if ingested, even in small quantities.
