Dangerous jellyfish spotted on Meath beach as sea swimmers warned about painful stings

A dangerous jellyfish has been spotted on a popular beach in Meath, with sea swimmers warned of potentially dangerous stings.

The lion's mane jellyfish, also known as the giant jellyfish, arctic red jellyfish, or the hair jelly, is one of the largest known species of jellyfish

They use stinging tentacles to capture, pull in, and eat prey and have been known to roam around the Irish Sea.

And it's those of you who usually head to Laytown and Bettystown beaches that need to be extremely aware of where you step these days.

Councillor Sharon Tolan warned people on social media: "Be careful when swimming, keep a close eye on children in the water and do try to keep your doggies away from them as they can be become quite sick if they lick or eat them."

What to do if you have been stung

You should:

  • Remove yourself from the water/vicinity of the jellyfish
  • If helping someone else make sure you don’t get stung yourself
  • Seek help and advice from lifeguards if you are on a lifeguarded beach
  • Try to carefully remove any attached tentacles by
  • flushing the sting area with seawater
  • removing tentacles with gloved hands, clean stick, tweezers, or scraping gently with the edge of a credit card. Don’t try to rub them off
  • Apply a 'dry cold pack' to the area (i.e. place a cold pack or ice inside a plastic bag and then wrap this package in a t-shirt or other piece of cloth)

  • Use HOT WATER for Portuguese Man O'War stings at approximately 45° Celsius for 20 minutes

  • Keep any puncture wounds clean and dry to avoid them getting infected

Mild symptoms of pain and swelling can be treated with simple painkillers such as paracetamol and ibuprofen, and mild itching at the sting site may respond to anti-histamine creams.
