Cold chain break: what it means and how to prevent it.
What it means and how to avoid it in refrigerated transport.
In the transport of perishable food products, maintaining a constant temperature is not just good practice but a fundamental step in protecting the product’s quality, safety and compliance. The so-called cold chain must be guaranteed at every stage, from storage to final delivery, and is considered an essential principle by European hygiene and health legislation. The ATP agreement also defines harmonised technical conditions for the transport of perishable goods.
What is a cold chain break?
A cold chain break occurs when a product that should remain at a controlled temperature undergoes a change in temperature — even a temporary one — during transport, loading, unloading or storage. In these cases, the freshness, shelf life and quality of the product may be reduced, with possible consequences for food safety too. EFSA also reminds us that perishable foods should be refrigerated promptly to below 5°C.
Why is it a problem that should not be underestimated?
Incorrect temperature management can encourage microbial growth. Some pathogens, such as Listeria monocytogenes, can even multiply at low temperatures, which is why temperature control remains crucial even under refrigeration. For this reason, European legislation requires suitable facilities and procedures to maintain and monitor appropriate temperature conditions during food handling.
The most common causes of cold chain breaks
Among the most frequent situations that can compromise the correct temperature are:
- prolonged stops during loading and unloading operations
- frequent opening of the cargo compartment doors
- vehicles that are not properly insulated
- refrigeration units that are not correctly sized
- a lack of constant temperature control and monitoring
EU food hygiene legislation does in fact require suitable equipment and/or procedures to maintain and monitor appropriate temperatures for food.
How to prevent the problem
To reduce the risk of cold chain breaks, it is important to rely on properly fitted-out vehicles, with efficient insulated bodies, good insulation and refrigeration systems suited to the type of goods being transported. It is equally important to plan deliveries well, limit the time the cargo compartment is left open, and periodically check the condition of the fit-out and the refrigeration unit. With this in mind, the ATP agreement sets out technical conditions to preserve the quality of perishable foodstuffs during transport.
