A potentially toxic bacteria which can be harmful to humans and animals has been found in Caerphilly Castle moat.
Natural Resources Wales has confirmed the presence of Cyanobacteria, also known as blue-green algae. In its mature stage of growth, the algae can form ‘blooms’ which in turn, can produce toxins which can be harmful to humans and animals.
Caerphilly County Borough Council’s Environmental Health team has warned people ensure pets, particularly dogs, do not enter the water of the castle moat.
Should pets come in contact with the water, owners are advised to thoroughly wash the animal with clean water and seek precautionary advice from a qualified vet.
The toxins can also be potentially harmful to humans, causing rashes after skin contact and illnesses if swallowed.
Cllr David Poole, Cabinet Member for Community and Leisure Services, said: “This advice certainly isn’t intended to cause undue concern and worry – but with in excess of 80,000 people expected to attend the Big Cheese festival in Caerphilly this weekend, it is important that residents and visitors are aware that animals should not be allowed to enter the water of the castle moat.
“Regular inspections of the body of water will continue to take place, and we will continue to work alongside Natural Resources Wales to address this issue.”
Residents with any concerns regarding this issue can contact Caerphilly County Borough Council’s Environmental Health team on 01495 235 213.
