Potentially toxic algae reported in Tomahawk Lagoon

Potentially toxic algae reported in Tomahawk Lagoon

High levels of potentially toxic blue-green algae (cyanobacteria) has been sampled from the Tomahawk lagoon in Dunedin, prompting a warning from the Otago Regional Council for people (and dogs) to avoid contact with the waters of the lagoon.

As part of weekly water quality monitoring, the water sample collected yesterday returned a high level of cyanobacteria from the upper Tomahawk lagoon.

Signs have been placed at the lagoon today to warn the public of the risks associated with the blue-green algae.

Cyanobacteria can produce toxins that are harmful to humans and animals if swallowed or through contact with skin. Exposure to cyanobacteria may cause symptoms such as skin rashes, nausea, tummy upset, and tingling and numbness around the mouth or tips of fingers.

Anyone experiencing health symptoms after contact with contaminated water should visit their doctor. Southern DHB Medical Officer of Health can be contacted on (03) 476 9800 to provide health professionals with information about those symptoms.

Cyanobacteria occur naturally but can increase rapidly during summer months.

If the water is green or has floating bright green or blue scums, all contact should be avoided. Not all cyanobacterial blooms are visible to the naked eye and toxins can persist after the bloom has disappeared.

Otago Regional Council will continue to monitor and update the public as the bloom changes.

Gordon Campbell: On The Claims About The CPTPP

As a Tufts study usefully explained, some of the basic mechanisms of the original TPP (and the CCTPP is not radically different in this respect) would – in practice – contribute to income inequality, by further tilting the existing imbalance between those reliant on profit-taking as a source of income, and those reliant on wages...

Under the original TPP deal, the Tufts team estimated, 5,000 jobs would have been lost across New Zealand. More>>
