Health Warning re Blue-Green Algal Bloom at Te Wairewa/Lake Forsyth

People are being reminded not to drink the water or swim in Te Wairewa/Lake Forsyth because continuing high levels of algal bloom in the lake could harm their health.

Dr Alistair Humphrey, Medical Officer of Health, says regular monitoring of the lake has shown it continues to have consistently high levels of blue-green algal bloom. The lake has had problems with algal bloom for some time

He says ingesting the water can be fatal for animals, including dogs, sheep, cattle, fish and birds.

Lake water is unsafe to drink and Dr Humphrey recommends people using the Little River Rail Trail and nearby recreational areas should only drink water from reliable sources

People swimming or showering in water with increased levels of algal bloom have been known to develop allergic reactions; asthma; eye irritations; rashes and blistering around the mouth and nose; and gastrointestinal disorders, including abdominal pain, cramps and diarrhoea.

He says other users of Te Wirewa/Lake Forsyth, including duck shooters, fishermen and boat users, should exercise caution in relation to recreational contact with the lake water. People should not eat shell fish from the lake until further notice.

For further information, or in the case of illness or suspected illness after swallowing water containing algal bloom, seek advice from your doctor. If your animals become sick, contact your veterinarian.

Community and Public Health will be placing warning signs around the Lake, advising people of the risks.
