Oleander (Nerium oleander) is an ornamental plant common in tropical and sub-tropical regions that is becoming increasingly widespread, even in temperate regions. Oleander poisoning may occur in animals and humans. The main active components contained in the plant are cardiac glycosides belonging to the class of cardenolides that are toxic to many species, from human to insects. This work describes a case of oleander poisoning that occurred on a small cattle farm and resulted in the fatality of all six resident animals. Furthermore, the investigation of the poisonous agent is described, with particular focus on the characterization of the oleandrin toxin that was recovered from the forage and rumen contents. The innovation of this study is the first description of the detection and quantification of the oleandrin toxin by liquid chromatography-high resolution mass spectrometry (LC-HRMS) in rumen.

The present case study concerns a case of predation of 4 individuals of captive pink flamingo in Emilia Romagna Region, Northeastern Italy. The pink flamingo (Phoenicopterus roseus) is a species included in the Red List of Threatened Species established by the International Union for Conservation of Nature (IUCN) which lists species in danger of extinction. During the Winter of 2013, 4 flamingos (2 in the Comacchio area, and 2 from Argenta and Codigoro oases - Ferrara province) were found dead some of them headless, with their bodies severely bitten. At first, a fox (Vulpes vulpes) was suspected to be the predator responsible for the killing and the birds were taken to the laboratory for further investigations. The investigations included: field observations, study of the predator behaviour, necropsy examinations, assessment of the intercanine distance, and genetic analysis on the predator's traces. The intercanine distance indicated that the predator could not have been a fox. The analysis of salivary DNA samples enabled us to establish that the predator was in fact a dog. This case highlights the importance of co-operation among the various branches of forensic sciences and the great usefulness of the roles filled by other veterinary forensic experts involved in solving crime.
