Also, MicroHibro allows comparing different predictive models and validate them by introducing user's data. In this paper, examples are provided to illustrate how predictive models can be incorporated in MicroHibro, and then, used to develop a Quantitative Microbial Risk Assessment model.

Introduction The increasing awareness on the need of strengthening micro- biological food safety is one of the major challenges for the globalized foodsector(Ercsey-Ravasz et al., 2012; Fungetal.,2018).Foodsafety riskmanagementhasbeenadoptedbyfoodindustriesasapartoftheir official control system throughout the production chain (Codex Alimentarius, 2007). End-product testing based on a hazard-based ap- proachhasalreadybeencataloguedasinefficientasitdoesnotprovide inmanycasesquantitativeinformationaboutthesanitaryconditionsof a given food product. Moving to a (quantitative) risk-based approach (i.e. estimation of the probability that a hazard is present in a food commodity)requirestheevaluationofgeneratedknowledge(statistical and computational methods) and interpretation of results through the development and application of resources (databases and software tools) readily available to be used by the food safety community, in- cluding risk assessors and managers, food operators or research in- stitutions (Membré and Guillou, 2016). Predictive food microbiology is a scientific field intended to study the microbial behaviour in food environments, including the development of mathematical models that can be deployed to perform predictions under certain specific conditions (Pérez-Rodríguez and Valero, 2013). The appli- cation of the knowledge generated in predictive microbiology has been mainly focused on the quantification of the bacterial behaviour in culture media and foods under certain environmental conditions. The kinetic parameters estimated from mathematical equations (i.e. maximum specific growth rate, lag time, inactivation rate, etc.) have been used to describe growth,inactivation,survivalorprobabilityofgrowthofseveralpathogens and/orspoilersinawiderangeoffoods.Theseoutcomesarecompiledina series of published books/briefs (i.e. Brul et al., 2007; McMeekin et al., https://doi.org/10.1016/j.ijfoodmicro.2018.10.007 Received 30 July 2018; Received in revised form 1 October 2018; Accepted 5 October 2018 Correspondingauthorat:DepartmentofFoodScienceandTechnology,UniversityofCordoba,Edif.Darwin-anexo(C1),CampusdeRabanaless/n,Crta,Madrid- Cádiz Km 396A, 14014, Córdoba, Spain.
