Deliverable 2.3 is linked with Task 2.3 of the ArtiSaneFood project, whose objective is to analyse the longitudinal data obtained from the microbiological and physicochemical surveys of raw materials, intermediate and final products, and the microbiological surveys of processing environments, conducted in Task 2.2. The present report compiles the variables or risk factors that lead to an increased contamination of the artisanal end products, as identified by adjusting both generalised linear models and stepwise regressions to the longitudinal data.
