Islanders are being warned about the discovery of what is thought to be blue-green algae in a pond in Shanklin, which has already killed several fish and could lead to the deaths of dogs and health complications for humans.
The pond by St Blasius Church at Big Mead appears to have a serious bloom of cyanbacteria – known as blue-green algae – according to local councillor Chris Quirk, who says it has already killed several fish in the pond.
If drunk, blue-green algae can case fatal liver damage to dogs and cats and can even be fatal to humans too. Toxins produced by the bacteria can cause skin rashes, nausea, vomiting, stomach pains, fever and headaches through contact with the skin and swallowing the contaminated water. Occasionally the toxins can cause more serious illness such as liver and brain damage.
Children are at greater risk than adults of developing problems because of their comparative lower body weight and in pets, some types of blue-green algae can kill a dog just 15 minutes to an hour.
The Environment Agency has been informed of the situation and warning signs are set to be erected.
Although laboratory tests are yet to take place, early tests show that the water’s O2 level are significantly below normal, indicating the presence of blue-green algae.
Not all blue-green algae blooms and scums are toxic but it is not possible to tell from appearance and so it’s best to assume they are harmful and take the following precautions:
– Do not swim in the water
– Do not swallow the water
– Avoid contact with the algae
– Do not eat fish caught from the water
– Observe and abide by any warning notices positioned around the water
Anyone who has come into contact with water containing blue-green algae should shower with fresh water immediately and anyone that has become ill should obtain medical attention.
