  • Benone Beach in Londonderry has been issued an "advice against bathing" notification due to the detection of blue-green algae.
  • The Department of Agriculture, Environment and Rural Affairs (Daera) confirmed high levels of the algae through its monitoring programme, leading to the temporary notice ahead of the bank holiday weekend.
  • This incident at the popular north coast beach comes amidst wider concerns over the proliferation of blue-green algae across Northern Ireland, particularly at Lough Neagh.
  • Over 100 blue-green algae detections have been made across Northern Ireland this year, with Lough Neagh experiencing noxious blooms for the third consecutive summer.
  • Factors contributing to the algae blooms include agricultural run-off, wastewater treatment, the invasive zebra mussel species, and rising water temperatures due to climate change.
