We included 219 plants in this review, considering only the plants that caused at least one demonstrated outbreak of poisoning. Plants reported as toxic in other regions and present in South America, but with no confirmed outbreaks of poisoning in this region, are not included. We report the main aspects of the epidemiology, clinical signs, pathology and economical importance of the poisonings. Initially, the toxic plants are described based on their toxic compounds, but because the toxic compound is unknown in 92 (42%) of the plants we also classify them according to the affected system. This review highlights the great diversity of toxic plants capable of affecting livestock in South America, and for this reason studies in this regard should be intensified. © 2023 The Authors  aLivestock  aPathology  aPLATAFORMA DE INVESTIGACIÓN EN SALUD ANIMAL  aPoisonous plants  aSouth America  aToxicology1 aMACHADO, M.1 aMICHELOUD, J.
