Blue-Green Algae Toxicity

Blue-Green Algae

Blue-green algae, formally known as cyanobacteria is a group of bacteria found in fresh water, brackish and sea water. Although cyanobacteria are not actually algae, the name was created from the algae appearance when clumped together on water.

Blooming from later spring to early autumn, it is most found in stagnant water during these periods of warmer weather. Although the bacteria cannot be seen, once bloomed it can be identified on top of the water as blue-green scum, small green flakes or green and brown speckles and often builds up around the edges of ponds and lakes with a foamy appearance.

The algae are highly toxic and following ingestion of contaminated water, your dog may begin showing the following clinical signs:

• Vomiting and diarrhoea
• Disorientation
• Breathing difficulty
• Excessive salivation
• Tremors
• Seizures

Although there is no reverse cure, systematic treatment can be offered but the prognosis is often grave. If you believe your dog has ingested blue-green algae, or if they begin showing clinical signs of algae toxicity following contact with water, contact the nearest veterinary surgeon immediately. Avoid allowing your dog to drink from or swim in water that you suspect may contain blue-green algae and look algae warning signs around lakes and ponds.
