Food safety cold chain: despite disrupted supply chains and price pressure

Food supply chains, and with them the logistics companies operating there, have been under massive pressure for some time. A complex interplay of various reasons have made empty shelves, long delivery times and price increases increasingly common worldwide.

Right now, food logistics specialists are particularly challenged to ensure compliance with the cold chain and thus the safety of the food entrusted to them.

These global factors influence food logistics

Global food supply chains are a highly complex and sensitive entity whose stability depends on diverse factors. If one factor gets out of balance, the industry is strong enough to compensate. However, when conflicts occur on multiple fronts, global impacts cannot be avoided. This is the situation we have been facing since the summer of 2021.

Since then, these three factors have caused short supply and increased prices: global conflicts, inflation, COVID-19 pandemic.

The moment in which goods pass from another cold chain actor to your responsibility is critical for food safety compliance.

The challenge: Time is short and a reliable core temperature measurement destroys the goods.

What can you do?

Apply this three-step procedure.

1. Infrared measurment

First scan the surface with an infrared measuring instrument such as the testo 104 IR.

If the temperature is clearly within the “green range”, the test is finished. For example: The yoghurt pots have a temperature of 5 °C (target: max. 8 °C).

Infrared measurement

2. Contact measurment

Is the temperature of some yoghurt pots over 8 °C?

Then measure with contact probe between two yoghurt pots.
Probe thermometer: testo 104-IR.


3. Penetration measurment

Is the temperature still too high?

Then perform a penetration measurement, for example with the testo 104 IR on one or more pots. The probe is inserted through the lid into the food and thus measures the correct core temperature.



When monitoring food storage, the targeted use of measurement technology is important - data loggers and data monitoring systems in particular have proven their worth here. Stationary monitoring is also often necessary for refrigerated cabinets and cold rooms.

For example with the radio data loggers testo Saveris 2, it is possible to efficiently check whether the installed refrigeration units provide the cooling capacity they are supposed to and that they have been planned appropriately for the premises. Because a faulty or inadequately dimensioned refrigeration unit results in unnecessary costs due to avoidable food spoilage.

The quality and safety of refrigerated and frozen (and therefore cold chain-mandatory) foods can only be guaranteed if the prescribed temperatures are maintained without interruption: From production to storage, transport, intermediate storage and storage in retail.

Additional certainty is provided by highly precise and seamlessly recorded measured values through targeted monitoring directly in the freight and in the truck. The transport data logger testo 184 is ideally suited for this purpose.
