WA Health is advising visitors to Mullaloo Beach to avoid any discoloured water, as it may be an algal bloom that was observed between Pinnaroo Point and the Ocean Reef Marina shorelines in recent months.
The warning follows several reports from members of the public of skin irritation, ear infections, burning throat and gastro-intestinal illness.
WA Health Senior Scientific Officer, Jared Koutsoukos said recreational activities such as swimming, diving, kayaking, jet-skiing, and fishing should be avoided in areas where significant water discolouration or scum was visible, as this water could contain algae.
“We’re advising beachgoers to stay out of the water at Mullaloo Beach, where there are signs of water discolouration,” Mr Koutsoukos said.
The Department of Water and Environmental Regulation will undertake sampling and analysis of the suspected algal bloom.
Department of Biodiversity, Conservation and Attractions and the City of Joondalup are working together to monitor and investigate the impacts of the recent nearshore algal events.
City of Joondalup will erect health warning signage as directed by WA Health.
Any person who comes into contact with discoloured water should immediately rinse it off with clean water and seek medical attention if they become unwell.
