Cryolog

Cryolog, a French company set up in 2002, is providing innovative traceability solutions: an adhesive label containing microorganisms that changes colour and becomes opaque when the product on which it is placed has been subjected to temperature abuse. It is linked to the bar code and prevents sales at check-out level where temperature abuse has occurred or after the expiry date. Applications include chilled foods, caterers' meals, and vaccines. It has won two French prizes for innovation and is generating promising economic spin-offs.
