Health warning for Lake Forsyth lifted
The Community and Public Health division of the Canterbury District Health Board has lifted its algal bloom health warning issued at Lake Forsyth/ Te Roto o Wairewa. This was issued on November 21, 2013.
Recent water testing at Lake Forsyth has shown the quantity of potentially toxic blue-green algae (planktonic cyanobacteria) in the lake has decreased and concentrations are now below the levels that are of concern to public health.
Dr Ramon Pink, Canterbury Medical Officer of Health, says Environment Canterbury’s sampling of Lake Forsyth will continue.
“The public will be informed if testing shows concentrations have increased and there is a risk to public health again,” Dr Ramon Pink says.
Facts about
cyanobacteria:
• The algae occur naturally but
can increase rapidly during warmer months.
• If the
water is cloudy, discoloured, or has small globules
suspended in it, avoid all contact.
• Not all
cyanobacterial blooms are visible to the naked eye and
toxins can persist after the blooms
disappear.
• Cyanobacterial concentrations can change
quickly with changing environmental conditions (e.g. wind).
If a health warning is in place avoid contact with the
water.
• If a warning is in place, people and animals
should not drink the water from the lake at any time, even
boiled water.
• Exposure to an algal bloom can cause
skin rashes, nausea, stomach cramps, tingling and numbness
around the mouth and fingertips. If you experience any of
these symptoms visit your doctor immediately and please let
your doctor know if you have had contact with lake water
when there is a health warning in place.
