Outbreak of Blue Green Algae detected in waters in Fermanagh

9th May 2024

Fermanagh and Omagh District Council has received confirmation from the Northern Ireland Environment Agency that blue green algae has been detected in the vicinity of Rossigh Bay, Lower Lough Erne, County Fermanagh. The Council advises residents and visitors to be aware of the potential presence of blue green algae in all waterways throughout the District at this time due to the potential risk to the health of humans and animals.

Blue green algae is a naturally occurring organism which can be found in loughs, rivers and ponds and is most prevalent between May to September due to increased temperatures and sunlight. When in bloom it can produce toxins which pose a health risk to humans and animals, therefore, it is recommended that you avoid contact with the affected water and shoreline and ensure pets and animals are also kept away.

Blue green algae can bloom very quickly, therefore, residents and visitors are advised to exercise caution around waterways during periods of warm weather and bright sunlight.

The Council has erected signage to alert visitors and residents to Rossigh Bay to the presence of blue green algae and to exercise caution in this area.

If you suspect there to be a presence of blue green algae, it is recommended that you avoid contact with the water and the adjacent shoreline and report the issue to the Environmental Health Service and via the Bloomin’ Algae App which is free to download from the AppStore or Google Play.
