Dublin beachgoers have been advised not to swim in the water at Dollymount Strand and North Bull Wall due to the presence of Lion's Mane jellyfish.

Dublin City Council issued the warning this afternoon:

The two north Dublin beaches should be considered off limits to swimmers until further notice.

Beaches along Ireland's east coast have issued several warnings this summer, urging swimmers to be cautious of the Lion's Mane jellyfish which have the potential to cause serious allergic reactions in those that are stung.

John Leech of Irish Water Safety revealed that there is at least one hospitalisation in Ireland each year following a sting from a Lion's Mane jellyfish and swimmers in Louth, Meath, Dublin, Wicklow and Wexford should be extremely vigilant.

"Everyone who is swimming this week in beaches along the East coast should be conscious of these Lion’s Mane jellyfish, which have been brought in with the spring tide in their numbers," he said.

"They have the potential to cause an anaphylactic reaction in someone who is stung, if they should be allergic, but much like a bee sting, you don’t know until you’ve been stung.

"We have seen a number of people hospitalised from this jellyfish and its sting is quite painful and different to other jellyfish found in Irish waters.

"The sting from their tentacles may last for days after they have died," he said.

"If you get stung, you need to wash it with salt water and remove the tentacles as soon as you can. Place a dry cold pack against it. As with anything, if the pain does not die down or the sting appears particularly bad, seek medical attention and go to A&E," he said.

Last weekend, two dogs became seriously ill after coming into contact with the septic jellyfish on Skerries beach.
