A case of zinc intoxication in young female cattle is described. The clinical signs consisted of reduced appetite, emaciation, submandibular oedema and diarrhoea. The source of zinc proved to be roughage harvested in the vicinity of a factory galvanizing steel tubes. In this roughage zinc levels between 3000 and 7300 mg/kg dry weight were found. In the liver of four animals zinc levels varied between 420 and 1600 mg/kg, and between 910 and 1680 mg/kg dry weight in the kidneys.
