Description
Summary:A methodology for food quality control, consisting of several consecutive concentric stages, is shown. It deals with a systematic and concentric study method, based on statistical results. The aim of this technique is to find the source of dissemination of a defined risk along the operations of a food process. It has been applied to the location of the presence of Listeria monocytogenes ( Lm) within the different stages in a poultry slaughterhouse. By means of application of statistical techniques like chi-square test, the classifying stage, where the carcasses are greatly handled, has been identified as the main source of the Lm in the studied poultry slaughterhouse. Besides, by means of the application of logistic regression the Lm psychrotropic behavior has been confirmed.
