[Cold chain --the concept of traceability-- practical applications].
Traceability makes it possible to monitor the properties of a foodstuff in general and its safety in particular. Based on the "refrigerated trio" concept developed by André Monvoisin, cold chain implementation conditions are examinated, with emphasis on the following three aspects, a safe product and early and continuous application of refrigeration. The TTT and PPP theories are presented. Following an overview of the French Academy of Medicine and the National Consumer Centre's recommendations, non compliance with the cold chain at household refrigerator level is discussed along with control equipment for refrigerators and products. Various indicators and integrators are presented and their described. Time-temperature integrators are examined in depth. In the conclusion, the authors stress the need to restore consumer confidence following recent foof-safety scares.
