In many parts of New Zealand, the drive to reduce possum numbers is underway, using poisons such as 1080. Warning notices are posted around most poisoning operations and warnings of aerial drops are published in the Public Notices column of local newspapers.
Possum control is a vital part of tuberculosis control.
The amount of TB in cattle and deer will be reduced as a result, and native forest areas will benefit too. Operators must be licensed to use 1080, and they make every effort to keep accidental deaths to a minimum. Dr Orr said 1080 is generally mixed with bait such as carrot or cereal to attract possums or rabbits. Unfortunately the bait may also be eaten by dogs and livestock, and dogs may be secondarily poisoned by scavenging poisoned carcases. Accidental deaths can be avoided if domestic animal owners understand the risks and take sensible precautions.
