Fresh warnings have been issued to the public about harmful blue-green algae floating in different areas of the Lake District.

South Lakeland District Council (SLDC) warned that there is suspected blue-green algae in a number of locations, including Windermere.

In the warning the council said: “Beware swimmers and pet owners - suspected blue-green algae in a number of lakes in South Lakeland including Windermere.

“ It can kill domestic pets and in humans can cause skin rashes, sore eyes and diarrhoea.”

Blue-green algae are a naturally occurring bacteria which is suspended in water or attached to rocks, often seen in concentrated ‘blooms’ as greenish or brown bundles, green flakes and sometimes bright blue clumps.

Not all blue-green algae blooms are toxic, however this cannot be determined purely by sight.

Contact with the bacteria in humans can result in diarrhoea if swallowed, as well as vomiting and can cause skin rashes.

Other symptoms can include fever, muscle and joint pain. If they come into contact with the water, people are advised to wash in clean water.

Blue-green algae can sometimes prove fatal for pets and livestock that come into contact with or ingest the bacteria.

The public has therefore been urged to avoid any contact with the algae and to keep animals away from suspected areas.

An SLDC spokesman said: “We would ask that the public are aware of the potential risks and heed warning signs.”

Tragically a British Bulldog, named Rolex, was victim to the toxic effects of the algae in July, after ingesting it.

Rolex’s owner, Alan Brown, had been on a break visiting family in the Lake District and was staying at White Cross Bay on the shores of Windermere.

The devastating images of Rolex on a ventilator were shared online by Mr Brown, serving as a stark warning to other pet owners.

The Environment Agency, who are responsible for water sampling, has devised a list with more information about blue-green algae on their website.

They say it is possible that any lake or water body not included on the map could still be affected by blue-green algae, and that people should visually assess all water they plan to enter and avoid contact with it if they have any concerns.
