title: Beef herd poisoning due to ingestion of tansy ragwort in southwestern Ontario.
abstract: Deaths attributed to Senecio jacobaea were investigated. The animal presented was a mature bull that was lethargic and dragging its feet. The bull was euthanized and 3 other cows died. Significantly, this disease has not been documented in Ontario before, and clinical signs of icterus or hepatoencephalopathy were not observed.
