MAF investigating kanakana illness
Posted on Friday, 7 October 2011 09:44 a.m.
The Ministry of Agriculture and Forestry received samples of kanakana, or lamprey, from Environment Southland last Thursday morning which are being tested at one of its Investigation and Diagnostic Centres.
The Ministry has reiterated information distributed by Environment Southland that the public do not consume kanakana that do not appear to be completely healthy.
Testing has provisionally identified the presence of the bacteria Aeromonas salmonicida and further work is being done to identify the exact strain of the bacteria affecting kanakana in the Mataura River.
It is expected that thorough testing will take up to four weeks to complete. The cause of the illness is being investigated and together with the fisheries industry work is being done to manage an appropriate response.
Different strains of the bacteria are known to occur and can affect a wide range of fish including salmon, trout and whitebait.
Until testing is complete, commercial fisheries and water users in the Southland area should be extra vigilant to check, clean and dry equipment and clothing between waterways.
Also be alert to any unusual marks or injuries seen on wild or farmed fish.
The bacterium poses no risk to human health, however as a precautionary measure, the public has been advised to avoid eating lamprey that do not appear healthy.
