The aim of the present study was to report an outbreak of natural poisoning by Cestrum laevigatum in dairy cattle in the “Agreste” region of Pernambuco state, Brazil. Epidemiological and clinical data were collected. Among a lot of 60 cows, eight became ill and four died. Two cows underwent necropsy, during which fragments of the central nervous system, liver, gall bladder, spleen and kidney were collected for histopathlogical analysis. Blood samples were collected for hematological and biochemical tests. The animals exhibited apathy, muscle tremors, reduced appetite, different degrees of dehydration and compromised reticulorumen dynamics as well as a small quantity of dry feces with the presence of mucus and blood. The laboratory exams revealed an increase in serum activity of aspartate aminotransferase and gamma glutamyltransferase as well as hypoalbuminemia. The necropsy revealed an enlarged liver and cutting surface with a nutmeg aspect as well as areas of hemorrhaging in the heart, trachea, abomasum, spleen, intestine and bladder. The microscopic analysis revealed centrilobular hepatic necrosis associated to accentuated hemorrhaging. These findings characterized poisoning by Cestrum laevigatum and led to the adoption of control and prevention measures.
