This paper describes clinical intoxication in horses, donkeys, cattle and sheep in Paraíba, northeastern Brazil between 1996-1999. Seed and whole plant samples contained 0.3-0.5% monocrotaline. Severe outbreaks were observed in the dry period of 1997, suggesting that the shortage of forage is an important condition for the occurrence of the disease. Centrilobular haemorrhagic necrosis of the liver also suggests acute intoxication when large amounts of are ingested.
