Public urged to be wary of bluegreen algae in waterways

NHS Fife has issued a reminder to be on the lookout for potentially hazardous bluegreen algae in local waterways.

A common seasonal occurrence, waters which have been affected by agricultural, domestic or industrial discharges are most at risk of developing algae.

In still waters, it can multiply during the summer to such an extent the water becomes discoloured, making it appear green, blue-green or greenish brown.

Shoreline mats of algae may appear and are usually coloured brown or black.

People and animals can be affected as a result of direct contact with water affected by blue-green algae, and NHS Fife is advising the public to be alert.

Dr Chris McGuigan, consultant in public health medicine, said: “Canoeists, wind surfers and swimmers who come into contact with the algal scum or who accidentally swallow affected water can suffer from complaints such as skin rashes, eye irritation, vomiting, diarrhoea, or pains in muscles and joints. They can sometimes be severe, in which case you should contact your GP.

“The risk to small animals like dogs is significant over the summer months as they tend to drink more water in the heat and may eat shoreline algal crusts.

“Fish caught in waters affected by blue-green algae should not be eaten and should not be fed to pets.”

Where monitoring reveals higher than acceptable levels of algal bloom, warning notices will be posted. However, anyone who finds a waterway they suspect is affected and which is not displaying a warning sign should contact their local environmental health service.
