To identify optimal method(s) for certification and subsequent monitoring of Mycobacterium avium subsp. paratuberculosis (Map)-unsuspected herds, certification-and-monitoring schemes were studied using a stochastic simulation model (“JohneSSim”). JohneSSim simulated the within-herd transmission and economic aspects of Map in closed Dutch dairy herds. The model was validated with field observations on Map-unsuspected herds. The current Dutch certification-and-monitoring schemes were compared with 11 alternative schemes in which individual and pooled fecal culture, ELISA, Johnin-intradermal test and γ-IFN ELISA were used, varying the test frequency, tested age group and number of tested animals.
