Health warning for Lake Whangape

3 December 2013

Cyanobacterial Warning Update: Health warning for Lake Whangape

A new health warning has been issued today for Lake Whangape, north of Huntly. The lake has had a rise in the number of cyanobacteria cells and a rise in biovolume since last tested one month ago.

Both Lake Waikare and Lake Ngaroto continue to have a cyanobacterial health warning in force.

Waahi, Hakanoa, and Rotoroa (Hamilton Lake), the other lakes that are tested regularly, all currently remain below the warning level for cyanobacteria, despite a rising trend.

Cyanobacteria are a form of algae which can produce toxins harmful to the health of humans and animals exposed to, or swallowing the water where the algae are growing.

Testing is carried out by Waikato Regional Council monthly during the warmer months, and two monthly over the winter. The lakes which are tested may indicate, to some extent, cyanobacterial levels in other shallow lakes in the region.

“During blooms, lakes should not be used for any activity that involves skin contact with the affected water. Swallowing water from lakes affected by blooms should also be avoided,” said medical officer of health Dr Richard Wall.

“Scums are a particular risk because they contain a high level of toxins. If contact with scum does occur, skin should be rinsed clean and clothing changed as soon as possible. This warning is particularly important for children.

“If people still choose to use the lakes when warnings are in place, or any other lake where there are visible changes to water colour, they should shower and change their clothing as soon as possible afterwards, even if no symptoms are noticeable.”

Symptoms include rash, skin and eye irritation; allergy symptoms such as hayfever and asthma; and possibly stomach upsets including diarrhoea and vomiting.

These symptoms may not appear until some time after contact with the affected water. Long-term exposure to cyanobacterial toxins may cause additional health risks.

Waikato Regional Council no longer routinely tests Lake Kainui; however, caution is still advised for users of this lake because of its history of cyanobacterial blooms.

Test results should be used for general guidance only, as cyanobacteria and their toxins are not evenly spread through any lake and may be concentrated in some areas by wind and water movements. Cyanobacterial blooms can happen very quickly when conditions for growth are favourable.

The Waikato DHB Population Health service would like to be informed about health problems that develop after exposure to any of the Waikato lakes. Health advice is also available from the Population Health on (07) 839 8899 in and out of hours.

Up-to-date information on cyanobacterial cell counts is available from local councils and Waikato Regional Council.

Gordon Campbell: On Drone Strikes And Judith Collins‘ Last Stand

The news that a New Zealand citizen was killed last November in a US drone attack in Yemen brings the drones controversy closer to home.

To the US, drones are a legitimate response to the threat posed by the al Qaeda organisation and its franchisees... To the US, the drones carry the added advantage of not putting US troops at risk on the ground, and minimises the need for putting them in large numbers in bases in the countries concerned, always a politically sensitive point.

The counter-argument, well articulated by security analyst Paul Buchanan on RNZ this morning, is that this particular drone attack can be said to amount to an extra-judicial execution of a New Zealand citizen by one of our military allies, in circumstances where the person concerned posed no threat to New Zealand’s domestic security.
