BATHERS are being warned to stay out of the water after toxic algae was found at an outdoor swimming pool.

Traces of blue-green algae, which occurs naturally during spells of warm weather, have been discovered at the Clarence Lido in Bury.

People, especially children, are being warned of the dangers.

The algae can rise to the surface to form scum which may look like blue-green paint or jelly.

This can be blown around the surface and may appear in different places at different times.

Potentially, the algae can affect the health of humans and animals because of the poisons it produces.

It can cause skin rashes, eye irritation, vomiting, diarrhoea, fever and pains in muscles and joints. This can be caused by swallowing algae or swimming through it.

Cllr Pam Walker, Bury council's public protection spokesman, said: "Blue-green algae can be found in reservoirs, lakes, canals and rivers.

"In Bury, we have seen an outbreak for the past few years at the Clarence Lido and, because it is a naturally occurring substance, it is very difficult to get rid of.

"Our best advice to people is to keep an eye open for it.

"We urge parents to ensure their children do not go near or into the water at the Lido to stop them coming into contact with the algae.

"Although there have never been any reports of long term effects, and certainly not deaths, the symptoms can be particularly unpleasant.

"Our best advice is stay away."
