Contaminated water kills Akaroa eels
The bodies of dead eels in an Akaroa creek have alerted health authorities to an ''extreme toxic contamination''.
The Canterbury District Health Board today warned an unknown toxin had killed wildlife in Walnut Creek, a popular spot for food gathering.
The contamination ran from Rue Noyer to the coast where eels and watercress were gathered.
Canterbury Medical Officer of Health Dr Alastair Humphrey said anything collected from the creek could be contaminated and should not be eaten.
Animals which had been in or near the creek and showed signs of illness should be taken to a vet immediately.
An Environment Canterbury investigation was underway to determine the toxin and its source.
