Blue Green Algae Lochindorb, by Grantown on Spey.

People visiting Lochindorb near Grantown on Spey are being warned of the presence of blue green algae at the Loch

Recent samples taken by SEPA at Lochindorb have indicated the presence of blue-green algae. Lochindorb is situated near the A939 approximately 6 miles north of Grantown on Spey.

As a precautionary measure, The Highland Council’s Environmental Health has posted notices next to the loch warning that contact with the algal scum should be avoided.

The notices, which take effect until further notice state that: “High concentrations of blue-green algae have been found in this water. Swallowing the water or algal scum can cause stomach upsets or more serious health effects. Contact with the water or with algal scum can cause skin problems. It is a sensible precaution for you, your children and your animals to avoid contact with the scum and the water close to it.”

Adjoining landowners are being advised of the situation as have NHS Highland. There are no reports of any effects on people, livestock or other animals.

Alan Yates, Environmental Health Manager added: “Blue-green algae exist in fresh waters in Great Britain and throughout the world; they are noticed when their concentrations increase to form “blooms” and when they form scums – looking like blue-green paint – or when they collect on the shore line.

“Some blue-green algae may give rise to adverse medical effects – but not always. Effects on people coming into contact with toxic scums include skin rashes, eye irritations, vomiting and diarrhoea, fever and pains in muscles and joints. Toxic algae have caused deaths of livestock and dogs, waterbirds and fish.

“The behaviour of algae is erratic. The level of its toxicity can fluctuate; it can appear one day, be dispersed by the wind and mixing and re-accumulate at any time.”
