#Jellyfish - Swimmers have been warned away from Seapoint and Sandycove on the south shores of Dublin Bay after sightings of potentially dangerous lion’s mane jellyfish in the water.

Dun Laoghaire-Rathdown County Council has put up warning signs in the relevant areas to advise the public on the large jellyfish, whose stings from hundreds of tentacles can cause anaphylactic shock — even many days after they have beached.

#Pollution - RTÉ News reports that a swimming ban was lifted yesterday on bathing spots at Seapoint and Killiney on Dublin Bay’s southern shore after high levels of E.coli were detected last Friday (30 June).

The bathing ban remains at Blackrock Baths pending the results of samples expected later today (Wednesday 5 July). Blackrock and Seapoint were subject to a similar ban for high E.coli levels back in January, according to TheJournal.ie.

More recently, the beaches at Dollymount and Sandymount were closed to swimming after heavy rains caused by a sewage spill in the River Liffey.
