Two Dublin beaches have been issued with a Do Not Swim notice following the presence of E. coli bacteria in the water.
The notices were issued by Fingal County Council yesterday after bathing samples were taken on Tuesday at Claremont and Malahide beaches.
The council has not revealed what the cause of the bacteria in the water is.
The notices will remain in place for 72 hours and resamples are set to be taken tomorrow, with new results expected to be revealed on Saturday.
Although the beaches are still open to the public, visitors have been urged to respect the advisory notices that have been put in place to protect the health of bathers.
People who intend to swim at any beach in Ireland are advised to check the water quality in advance, this information can be accessed through the EPA website or the notice board at the entrance to any beach.
