Cholecalciferol as an alternative to sodium monofluoroacetate (1080) for poisoning possums

Large scale control of possums (Trichosurus vulpecula) in New Zealand is dependent on the use of sodium monofluoroacetate. Although this is highly effective, its use is restricted and there is public pressure to find alternatives. An acute toxicity programme has been set up to identify safer, more humane and more specific toxins. Possums were dosed with a new rodenticide, cholecalciferol (Vitamin D3). Interim results indicated that cholecalciferol had an LD90 of 20-50 mg/kg in the possum
