Shetland residents are being advised to exercise caution around lochs on the island following concerns over the spread of blue-green algae.
The Scottish Environment Protection Agency (SEPA) has been unable to carry out its usual regular water testing at lochs suspected to contain the bacteria due to the ongoing Covid-19 restrictions.
Blue-green algae commonly exists in fresh waters across the UK and is commonly noticed when concentrations begin to form blooms.
Contact with the bacteria can cause a range of medical effects, including skin rashes, eye irritations, vomiting and diarrhoea, fever and pains in muscles and joints.
Toxic algae has in the past caused the death of livestock and dogs.
In the interim, officials are asking residents to exercise caution where the algae can be seen in lochs.
Reports have so far been received of blooms in the Loch of Brindister, Kirkhouse Water near Bixter and in Clickimin Loch, Lerwick.
Members of the public are advised to keep dogs and livestock away from the lochs and refrain from bathing in infected waters.
Fisherman are also being advised to be cautious.
