Two cases of leptospirosis due to infection with a member of the Hebdomadis serogroup are described in farm workers on a Victorian dairy farm. The source of infection appeared to be the milking herd which had elevated serum antibody titres against a member of the Hebdomadis serogroup. Agglutinin‐absorption testing of one patient's serum indicated that the infecting serovar was hardjo . A survey of 1,144 cattle entering abattoirs throughout the State indicated that 44.3% of these animals showed serological evidence of past or present infection with leptospira of the Hebdomadis serogroup and the potential risk for people with occupational contact with cattle is emphasised. The importance of considering leptospirosis in the differential diagnosis of all patients with influenza‐like symptoms or pyrexia of unknown origin and having occupational contact with animals, especially cattle, is discussed.
