The QMRA model is set up using a modular approach. It consists of the following modules: farm, transport & lairage, slaughter and processing, preparation and consumption. The outcome of the latter module is fed into the dose-response model to predict the risk. The model uses Monte Carlo sampling as a means for dealing with variability in the parameters. A user-friendly interface has been developed for the QMRA model for Salmonella in pigs. A stand-alone executable of the code has been generated in which the farm and slaughtering phase have been incorporated as separate optimized modules. The code has been shielded from the user. Parameter inputs can be made and several types of output are provided (e.g. storing graphs and data, exporting results to pdf). The data within the models comes from literature and expert opinion. The data-file driven mode of the QMRA has been replaced by a graphical front-end. The presentation of the user-interface includes screens for each of the modules (farm, slaughter, consumption, dose-response), where the user may enter their (distribution of) parameter values. Finally simulation settings can be entered, the model ran, and the results are presented in a clear manner
