Seven beaches in Co Cork will remain closed to swimmers until at least Wednesday, when results of tests carried out on water there are known.
Cork County Council has advised against swimming at the beaches due to concerns about levels of the E coli bacteria in the water.
The council said further sampling was carried out today at Youghal, Claycastle, Redbarn, Coolmain, Garretstown, Oysterhaven and Garryvoe beaches.
They said the results of the tests will be available on Wednesday evening.
Public notices banning swimming were first posted last Friday.
Cork County Council said the closures were introduced as a precautionary measure after heavy rainfall over the last two months caused the levels of E coli at the beaches to breach EU mandatory permitted values.
