Potentially Toxic Blue-Green Algae Reappears In Otago

The Otago Regional Council (ORC) is warning the public to avoid contact and keep their dogs away from Lake Waihola, south of Dunedin, after the reappearance of potentially toxic blue-green algae.

ORC director of environmental information and science John Threlfall said following the all clear earlier in the month, the potentially toxic blue-green algae Anabaena lemmermanni had come back to the lake.

This algae, which is dark green, can produce a series of toxins which are then
passed to the water and can be fatal to dogs and cause illness in people.

It was discovered in Lake Waihola and at Tomahawk Beach in early December, but had recently been given the all clear.

Otago-Southland medical officer of health Dr Marion Poore said people swimming in water with increased levels of algal bloom have been known to develop allergic reactions: asthma, eye irritations, rashes, blistering around the mouth and nose, and gastro-intestinal disorders, including abdominal pain, cramps, and diarrhoea.

People should not swim in Lake Waihola, and other water users, including fishermen and boat users, should exercise caution, Dr Poore said.

Any reaction depends on the type of toxins present, and the concentration of the toxin in the water. The higher the concentration of toxins and the longer the contact with the water, the more severe the symptoms are likely to be.

Dogs are particularly susceptible to poisoning from both mat-forming and free-floating toxic algae as they enjoy being in the water and can consume these algae intentionally or by accident. Livestock are also at risk from poisoning from cytotoxins and should be provided with alternative drinking water.

Symptoms of poisoning in animals exposed to the type of toxins present in anabaena mats include lethargy, muscle tremors, fast breathing, twitching, paralysis, convulsions. In extreme cases, death can occur within 30 minutes after signs first appear.

“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 immediately," Dr Poore said.

ORC will put out warning signs at the locations where the algae has been found and will continue to monitor the situation.

Gordon Campbell: On The Tokenism Of New Zealand's Role Against Islamic State

To date, the Opposition has continued to occupy itself with the marginalia of the issue. E.g. whether Key did or didn’t know whether Barack Obama would be present at the US briefing last week on IS, or whether New Zealand’s military involvement is or isn’t already a fait accompli.

It might be better to tackle the issue, head on. Our contribution against IS will be to send SAS forces to train the Iraqis? That’s like offering trainers to General Custer just as the 7th cavalry reached the Little Big Horn.
