Talisia esculenta is a tree that produces pitomba, a fruit consumed by human beings in several regions of Brazil. The current study reports 3 outbreaks of poisoning by leaves and fruits of T. esculenta affecting sheep and cattle and the experimental reproduction of the disease in sheep. In the first investigated outbreak, sheep ingested the leaves of the plant; another outbreak affected cattle and sheep that ingested leaves and fruits; and in a third outbreak, sheep ingested only the fruits. The animals developed severe nervous signs, but most recovered. Poisoning was reproduced experimentally in 5 sheep by the administration of 30-60 g of leaves/kg body weight and in 2 sheep with doses of 5 and 10 g of seeds/kg body weight, respectively. No significant necropsy or histologic lesions were found.
