The Highland Council’s Environmental Health team is advising caution as blue-green algae has been found in Loch Watten, Caithness.

During periods of prolonged warm weather, the chance of Blue Green algae (cyanobacteria) affecting water courses, particularly ponds, lochs and canals (as well as rivers), increases significantly. Sometimes the blue green algae can form blooms, which can release toxins into the water. 

Samples taken at Loch Watten in Caithness have indicated the presence of blue-green algae.

Contact with blue-green algae can have health effects for humans and animals; the situation is being investigated by Highland Council Environmental Health Department in partnership with NHS Highland Public Health Department and wider colleagues. As a precautionary measure contact with the algal scum should be avoided by people and pets.  Notices will be posted next to the loch warning that contact with the algal scum should be avoided.
