Sodium monofluoroacetate (1080) risk assessment and risk communication.
Sodium monofluoroacetate (1080) is a vertebrate pesticide widely used for possum control in New Zealand. Fluoroacetate is also a toxic component of poisonous plants found in Australia, South Africa, South America, and India. Because of its importance and effectiveness in pest control and the highly toxic nature of this compound, its acute sub-lethal and target organ toxicity have been extensively studied. In relation to its use as a pesticide its environmental fate, persistence, non-target impacts and general toxicology have been and continue to be extensively studied. Toxic baits must be prepared and used with extreme care, otherwise humans, livestock, and non-target wildlife will be put at risk. The high risk of secondary poisoning of dogs is a cause for concern. 1080 acts by interfering with cellular energy production. Possums die from heart failure, usually within 6-18 h of eating baits. Long-term exposure to sub-lethal doses can have harmful effects and strict safety precautions are enforced to protect contractors and workers in the bait manufacturing industry. Considerable care is taken when using 1080 to ensure that the risks of using it are outweighed by the ecological benefits achieved from its use. When its use is controversial, risk communicators must take care not to trivialise the toxicity of the compound. The benefits of 1080 use in conservation, pest control, and disease control should be weighed up alongside the risks of using 1080 and other techniques for pest control.
