Warning over toxic algae in River Hamble with dog owners urged to keep their pets out of the water

Dog walkers and visitors have been warned about a potentially toxic blue-green algae in a river.

The bacteria, which can be harmful to humans, has been reported along parts of the River Hamble, according to Eastleigh Borough Council, an area popular with walkers and visitors and backing onto both Holly Hill Woodland park an the River Hamble Country Park.

Following the alert from the Environment Agency (EA), the local authority is advising members of the public to avoid any contact with the water until further notice and dog owners are urged to prevent their pets from entering or drinking from the water.

The EA has warned that the algae can produce harmful toxins that may pose risks to both humans and animals.

It often appears after a spell of warm weather, and reported symptoms include skin rashes, stomach pain, diarrhoea, eye irritation, blistering, and nausea.

A spokesperson for the council said: “Anyone who believes they, their child, or their pet may have been affected after coming into contact with the water is advised to seek medical attention immediately. Pet owners should contact their veterinary surgeon without delay.”

Suspected sightings of blue-green algae can be reported to the Environment Agency Incident Hotline on 0800 80 70 60, or by emailing photographic evidence to [email protected].
