Officials have lifted a red-flag bathing ban at several beaches along the Co Derry coast following a blue-green algae warning.
Blue-green algae can cause illness in humans but can be fatal for pets.
Warnings over the bacteria were issued for Portstewart and Castlerock beaches as a precaution last week and then later extended to Downhill beach.
The RNLI red-flag status at Benone Strand, Castlerock Beach and Downhill Strand have now been removed following tests.
The status of Portstewart Strand is not yet known.
A spokesperson for Causeway Coast and Glens Borough Council confirmed the decision to remove the red-flag status on Monday.
They said tests revealed algae levels are “well below the World Health Organisation (WHO) guideline level” in water samples collected by DAERA.
The removal of the red-flag status means people can now enter the water again.
Blue-green algal blooms have been detected at a number of sites across the North of Ireland during the recent good weather.
