Interpretive Summary: This report describes a plant poisoning event in Western Australia causing the death of fifteen sheep. One of the poisoned sheep was necropsied and the pathology of the poisoned sheep is described. Monofluoroacetate was detected in rumen contents from the necropsied sheep. The case history, pathology observations, and detection of monofluoroacetate in the rumen contents support a diagnosis of monofluoroacetate intoxication. This is the first example of detection of monofluoroacetate in the rumen contents of an animal poisoned by a plant containing monofluoroacetate.

Technical Abstract: This report describes the history and investigation of a suspected plant poisoning event in Western Australia where fifteen sheep died. One of the poisoned sheep was necropsied and gross and microscopic pathology of the poisoned sheep is described. Monofluoroacetate was detected in rumen contents from the necropsied sheep. The case history, pathological changes, and detection of monofluoroacetate in the rumen contents support a diagnosis of monofluoroacetate intoxication. A review of the literature suggests this is the first example of detection of monofluoroacetate in the rumen contents of an animal poisoned by a plant containing monofluoroacetate.
