Toxic algae found at Seven Sisters Country Park

An algae that can be toxic to people and pets has been found at an East Sussex beauty spot.

A spokesperson for the South Downs National Park Authority (SDNPA) told the BBC blue-green algae had been detected in the meanders of the Cuckmere River at Seven Sisters Country Park.

"We are advising visitors... to stay out of the water and to keep dogs on leads at all times," they said.

"Anyone who has been in contact with the water and feels ill should seek immediate medical or veterinary advice."

The spokesperson said that blue-green algae naturally occurred, but some could be toxic to both humans and animals.

Blue-green algae in fresh water is suspended in the water or attached to rocks and other surfaces, according to the Environment Agency.

They are important contributors to aquatic biology, but bloom and scum forming blue-green algae can produce toxins, it adds.

"These toxins can kill wild animals, farm livestock and domestic pets," says the Environment Agency in a document.

"In humans, they can cause rashes after skin contact and illnesses if swallowed.

"Not all blue-green algae blooms and scums are toxic, but you can't tell just by looking at them, so it's best to assume they are."

The Environment Agency told the BBC they have installed signage around the park to not enter the water.

Samples had been collected, with results expected by the end of the week, it added.

The SDNPA spokesperson said they would continue to provide updates as any new information becomes available.
