Summary

This study is a discussion of the growth and inactivation models that can be used in a stepwise procedure for quantitative risk assessment. First, rough risk assessments are performed in which orders of magnitude for microbial processes are estimated by the use of simple models. This method provides an efficient way to find the main determinants of risk. Second, the main determinants of risk are studied more accurately and quantitatively. It is best to compare several models at this level. By comparing various models the main determinants of risk are studied from several points of view, and risks can be assessed on a broad basis. If relevant, the process variations can be stochastically described in the third level of detail. The proposed stepwise procedure provides a structured method of risk assessment and prevents the researcher from getting caught in too much complexity.
