The challenge when addressing food safety problems is to make a synthesis and assessment of the current state of knowledge, but also the lack of knowledge and uncertainties. The synthesis and assessment of knowledge has usually been in the form of a scientific review resulting in an opinion with conclusions and recommendations addressing the terms of reference. Systematic literature reviews, metaanalyses, qualitative and/or quantitative and/or microbial risk assessments offer alternative approaches for looking deeper into the food safety problems. The purpose of risk assessments is to enable risk managers to make informed risk management decisions using all available knowledge and insights, complementing socioeconomic, legal and political considerations. In other words risk assessment is the scientific part of risk management. I will try to illustrate this by examples (Salmonella in layers, Campylobacter in chickens, and a qualitative and quantitative approach on Salmonella in pigs from the last 10 years.
