There are many factors which may influence food safety. Usually these are natural or productional induced biological, chemical or physical hazards with the potential to cause an adverse health effect. In Germany implemented instruments to ensure food safety guarantee a high level of biosafety concerning these in the context of naturally, accidentally or production-related contaminations occurring type of hazards. In contrast to this there is no system available in Germany yet which assesses the risk resulting from the deliberate and intentional caused contamination which is called a malicious contamination. We therefore analysed a prioritisation tool which is developed by the Food and Drug Administration (FDA) (Center for Food Safety & Applied Nutrition, 2007) and which can be used to assess the vulnerabilities within a system or infrastructure in the food industry. The approach and workability of the system has been evaluated by applying it in selected meat processing companies. The system enables companies already to identify possible points of malicious contamination but is too complex for being a useful tool especially for small companies. Based on our experiences the system still needs substantial adaptations to fulfil German demands.
