Seven pigs were poisoned by feeding from 1 to 3 months with Senecio jacobaea (“ragwort”). Clinically, the disease induced was characterised by dyspnœa and fluctuating pyrexia, anatomically by firm, heavy, discoloured, oedematous lungs and histologically by pulmonary oedema, congestion, haemorrhage and alveolar epithelialisation, and by hepatic and renal karyomegaly.
Ragwort poisoning in pigs was compared with groundnut poisoning and it was concluded that the two are unlikely to be confused.
