Blue-Green Algae has been identified at several locations on the River Medway Navigation between Tonbridge and Yalding.
What are Blue-Green Algae?
Blue-green algae are natural inhabitants of inland waters, during calm weather they rise to the surface to form a scum. This may look like paint, or jelly and may form flocs. Scums may be blue-green, grey-green, greenish-brown or occasionally reddish-brown in appearance. They may disappear and reappear on subsequent days and, as a result of wind action, may accumulate on the shoreline. Sometimes these algae may release toxins into the water.
Illnesses including skin rashes, eye irritation, vomiting, diarrhoea, fever, pains in muscles and joints have occurred in some recreational users of water who swallowed or swam through algal scum. There have been no reports of long-term effects or death in humans, but in some cases the illnesses were severe.
Blue-green algae can be toxic to dogs. Call your vet immediately if you suspect poisoning
Although algal scum is not always harmful, it is a sensible precaution to avoid contact with the scum and the water close to it.
