Risk-based shipping design, loggers and excursion assessment at receipt.
Cold chain is a system
The presence of coolant is not enough. Packaging, route, season, duration and transfer points affect risk. The configuration should be assessed for the actual shipping profile and stated material conditions.
Meaningful monitoring
A logger is positioned to answer the shipping question and has known calibration, range and sampling interval. Start, stop and time zone should allow alignment with the shipment. An indicator without history may provide less information than a complete time series.
Receipt assessment
The recipient checks integrity, monitoring data and documents before releasing material. An excursion is assessed against scientific evidence and a predefined procedure, not solely from the appearance of the package.
