The Persistence And Secondary Poisoning Risks Of Sodium Monofluoroacetate (1080), Brodifacoum, And Cholecalciferol In Possums, C. T. Eason, G. R. Wright, L. Meikle, P. Elder
Proceedings of the Seventeenth Vertebrate Pest Conference 1996
To determine the risk of secondary poisoning for animals preying on sub-lethally poisoned brushtail possums, captive possums were treated with near-lethal doses of sodium monofluoroacetate (1080) or brodifacoum, and toxicant concentrations in blood and tissue were monitored over time. Sodium monofluoroacetate was rapidly eliminated from the blood (within three days). Brodifacoum was retained in the liver and, to a lesser extent, the muscle of possums for eight months after dosing. To determine the potential risk for animals scavenging on the carcasses of possums poisoned with cholecalciferol, cats were fed poisoned carcasses for six days. No changes in behavior, appetite, or …

The Distribution And Significance Of Anticoagulant-Resistant Norway Rats (Rattus Norvegicus) In England And Wales, 1988-95, Alan D. Macnicoll, Gerard M. Kerbms, Nicola J. Dennis, J. Erica Gill
Proceedings of the Seventeenth Vertebrate Pest Conference 1996
Between 1988 and 1995 populations of rats on agricultural premises were sampled to investigate the distribution of anticoagulant-resistant rats in England and Wales. In total, approximately 1,670 rats from 115 locations were tested for resistance to warfarin. Rats that were warfarin-resistant were subsequently tested for resistance to difenacoum, and since 1991 for resistance to bromadiolone. In some cases rats were also tested for resistance to brodifacoum, and in 1995 for resistance to flocoumafen. The results of these tests showed that there was a high prevalence of resistance to the first-generation anticoagulant, warfarin, in several regions of England and Wales. Rats …
