This study describes a case of accidental poisoning with Melia azederach in cattle in Buenos Aires Province, Argentina. The clinical signs were staggering gait -mainly in the pelvic limbs- indifference to stimulus, permanent decubitus and death. The histopathological study of the skeletal muscle samples obtained from necropsy showed different degrees of segmental degeneration and fragmentation of muscle fibers. Some myofibers evidenced myofibrillar lisis and homogeneous, slightly eosinophilic, sarcoplasm stain. In the small intestine, severe lymphocyte necrosis in the Peyer's patches was observed. The latter was also noticeable in the splenic white pulp, in the lymphoid follicles of the mesenteric lymph node, and in the bronchial-associated lymphoid tissue. Muscle enzymes were higher than the reference values. Considering epidemiologic data, clinical signs, pathological findings and results from complementary laboratory analysis, M. azederach poisoning in cattle was diagnosed
