I propose to take Questions Nos. 2 and 15 together.
Leptospira are among the most widely distributed bacteria in nature causing disease in most species of animal and in man throughout the world.
Leptospirosis in cattle has been found among dairy herds in this country and the severity varies depending on the immune status of the herd. Advances in diagnostic techniques and the virtual elimination of brucellosis, which tends to mask leptospirosis, have identified leptospirosis as a cause of milk drop, abortions and perinatal death in some herds. There is, however, no evidence to indicate an increase in the national incidence and, as the disease can be readily controlled by vaccination or by antibiotic therapy, I see no need for a slaughter and compensation policy in respect of affected herds.
My Department's veterinary laboratories provide a diagnostic and advisory service to herdowners through their veterinary practitioners and there is a leaflet on leptospirosis available from the Department which outlines the control procedures and farm management practices which should be followed.
