Anticoagulant rodenticides were first discovered during ingvestigations into mouldy sweet clover poisoning in cattle<sup>1</sup>. In this condition, naturally occuring coumarin in clover is converted by fungi to a toxic agent, dicumarol, which causes a haemorrhagic syndrome when ingested. Initially, warfarin was synthesised and used in this way for rodent control, but as rodents have developed a resistance to the substance new, second-generation anticoagulant rodenticides have been developed. These include difenacoum, bromadiolone, coumafuryl and brodifacoum amongst others, which may all causes toxicity in animals in the same way as warfarin.
