The results of organized control of Johne's disease in the Province of Friesland are evaluated in the present retrospective study. The relationship between the methods of diagnosis adopted and the post-mortem findings is examined. In addition, the results of this control on a number of farms taking part were studied with reference to the number of animals taken over by the Animal Health Service. Organized paratuberculosis control in the Province of Friesland was not successful in reducing the number of cases of Johne's disease. Both the number of participating farms and the number of animals taken over increased. The numerical yield of control was low. Control failed because of the fact that the diagnostic procedures adopted (complement fixation test and intradermal johnin test) are inadequate. Other methods should therefore be considered. Vaccination against Johne's disease would appear to offer good prospects and is cheaper.
