The application of the generated knowledge in predictive microbiology has been mainly focused on the quantification of the bacterial behavior in culture media or foods under certain environmental conditions. The kinetic parameters estimated from mathematical equations (i.e. maximum growth rate, lag time, inactivation rate etc.) have accurately described growth, inactivation, survival or probability of growth of several pathogens and/or spoilers in a wide range of foods. Nonetheless, the dissemination of this knowledge to food industries in order to optimize food processes and to provide assistance in decision-making in a short time frame is still being developed. To this sense, the routine and successful use of mathematical models by the food industry, governmental or educational agencies, will depend on the development of appropriate and useful applications (software packages and on-line platforms) of easy management. The increased use of models in the food industry might depend on the availability of user-friendly software, which encompass predictive models and allow different users to retrieve information from them in a rapid and convenient way. A flexible and upgraded tool assessing the behavior of potential microbial hazards along the food chain and their impact on public health could be highly valuable for food safety decision makers. The performance of risk-based metrics and the establishment of microbiological criteria could help to identify critical steps along the food chain that influence on the final risk associated to a specific pathogen. Some examples of how to establish microbiological criteria basing on risk-based metrics and predictive models will be provided.
