A model for the assessment of microbiological risks, which may originate from intentional contamination of the feed chain, was developed by the Federal Institute for Risk Assessment. It covers different feed processing chains and different microorganisms. Numerous scenarios were defined and evaluated as well as a sensitivity analysis performed. The application of the model allowed the identification of process parameter combinations which would be inefficient in worst case scenarios, e.g. where a highly heat resistant strain was selected for the intentional contamination. Equally important, this analysis can help to target specific control efforts. Based on the outcome of these simulations, recommendations can easily be given in crisis situations to which temperature-time combination processes should be adjusted to ensure the production of safe compound feeding stuff. This research will help to better understand and predict the consequences of bioterrorist attacks in the feed processing chain.
