Poisonous blue-green algae has once again been found at Pen y Fan Pond, Caerphilly County Borough Council has confirmed.

It is the third time in around two years that blue-green algae has been discovered at the pond, which is near Oakdale.

Blue-green algae, also known as cyanobacteria, occurs naturally in rivers, streams and lakes and can multiply and form ‘blooms’ during periods of hot weather.

The algae can produce toxins harmful to both humans and animals, causing rashes and irritation.

The RSPCA and the British Veterinary Association have both reported deaths to animals associated with blue-green algae, including pets.

In a statement, the council urged residents to keep themselves and their pets away from the water.

Should pets come in contact with the water, the council has urged owners to thoroughly wash the animal with clean water and seek advice from a vet.

Cllr Chris Morgan, who is the council’s Cabinet Member with responsibility for Green Spaces, said: “We would like to assure residents that the park remains safe to visit and enjoy, without causing undue concern or worry. However, it is vital that no recreational activities, including fishing and public access of the pond itself takes place.

“Visitors are also urged to ensure animals do not enter the water at Pen y Fan Pond.”

Cllr Morgan added: “Signage has been placed around the pond and regular inspections of the body of water will continue to take place. Our officers are also working alongside Natural Resources Wales to address this issue”.
