Deadly jellyfish have 
spread to Dublin's northside beaches and have forced the closure of Claremont beach in Howth.

The Lion's Mane jellyfish, which can cause anaphylactic shock and death, forced 
warning notices on beaches on the southside of the city last week that are still in place.

Now Fingal Council has put a red flag on Claremont beach after council staff removed several of the dangerous jellyfish from the area.

Swimmers were also banned from four beaches along the Dublin coast yesterday because of contaminated water.

On the southside, Dun Laoghaire-Rathdown Council issued bathing ban notices along the shore at Blackrock Baths because of the poor water quality.

A council spokesperson said the water on all other beaches in the council area was "excellent".

She added that sample results were due back tomorrow and if these met standards the ban would be lifted.

Dublin City Council has also issued swimming ban notices for Sandymount and Merrion beaches.

On the northside, Fingal Council has issued warnings to swimmers at Malahide beach.

A council spokesperson said there was a permanent red flag at Malahide beach because of the dangers of the nearby channel and boat traffic, so swimmers should never use this beach.

She pointed out, however, that swimmers at Low Rock and High Rock, between Portmarnock and Malahide, should also be aware of the water 
contamination.

The spokesperson explained that ban notices were only placed on designated beaches with lifeguards. Low Rock and High Rock were not designated but were still popular swimming areas and the Malahide contamination would affect these two points as well.

She said the ban had been put in place because of the high level of contamination in the water, which was thought to be due to a "sewer overflow".

The ban will last for 72 hours and the HSE has been notified to arrange further sampling.

Last week, warning notices were put on Sandycove, Killiney and Seapoint beaches after 77 Lion's Mane jellyfish were removed from Sandycove by council workers.

The jellyfish have hundreds of long, hair-like tentacles and their sting can cause "excruciating pain" to bathers.

In extreme cases they can cause anaphylactic shock and death.

More common symptoms include nausea, vomiting and respiratory distress.

People are being urged to swim in lifeguarded areas only.

They should seek medical attention for anything other than minor symptoms where they are stung.
