Cold chain
Updated 2026-07-12 · Reviewed by: Redazione ce85204 — revisione editoriale assistita da AI (2026-07-12)
The cold chain is governed by Annex II, Chapter IX, of Regulation (EC) 852/2004: food supporting the growth of pathogens must not be kept at temperatures that would result in a risk to health and the cold chain must not be interrupted, save for limited periods. Numeric temperatures by category are set by specific or national rules.

Commentary
The general rule of Chapter IX
Regulation (EC) 852/2004 governs the cold chain in Annex II, Chapter IX (provisions applicable to foodstuffs). The central provision is point 5: raw materials, ingredients, intermediate products and finished products likely to support the reproduction of pathogenic micro-organisms or the formation of toxins are not to be kept at temperatures that might result in a risk to health, and the cold chain is not to be interrupted Annex II, Chapter IX, point 5 of Regulation (EC) No 852/2004. The rule does not set a single numeric value: it adopts an outcome standard ("temperatures that would not result in a risk"), leaving quantification to other sources.
Point 6 completes the regime on the cooling side: where foodstuffs are to be held or served at chilled temperatures they are to be cooled as quickly as possible following the heat-processing stage — or the final preparation stage if no heat process is applied — to a temperature which does not result in a risk to health Annex II, Chapter IX, point 6 of Regulation (EC) No 852/2004. It is the legal basis for rapid chilling: the intermediate temperature band is where pathogens multiply, and it must be crossed quickly.
The limited derogations
Point 5 expressly provides a flexibility valve: limited periods outside temperature control are permitted, where necessary to accommodate the practicalities of handling during preparation, transport, storage, display and service of food, provided that it does not result in a risk to health Annex II, Chapter IX, point 5 of Regulation (EC) No 852/2004. The derogation is specific and conditional: it concerns "limited periods", responds to concrete practical needs (plating, counter display, service) and must never generate a risk. It is therefore not a licence to interrupt refrigeration at will, but an acknowledgement that some operations require a brief departure from controlled temperature. In our view, the duration and conditions of the derogation should be defined and justified in the food safety management manual, consistently with the hazard analysis.
The numeric temperatures: where to find them
Regulation 852/2004 does not list temperatures by food category. Specific values come from two sources. First, the specific rules for products of animal origin in Regulation (EC) 853/2004, which set storage and transport temperatures for meat, fishery products, milk and dairy and other products Article 3 of Regulation (EC) No 853/2004. Second, national rules, which for food not covered by 853/2004, or for the service stage, set reference temperatures: for Italy the framework is on the Italy page. This is also why correct temperature settings in a restaurant must be checked against the rules applicable to the individual category, not against a single assumed value.
Cold chain, transport and HACCP
The cold chain is not only about storage: Chapter IV requires that vehicle load compartments and containers used for transport keep food at an appropriate temperature and, where necessary, allow it to be monitored Annex II, Chapter IV, point 7 of Regulation (EC) No 852/2004. In the HACCP system, temperature control is often a critical control point or an operational prerequisite: monitoring is carried out by recording the temperatures of refrigerators, cold rooms and blast chillers Article 5(2) of Regulation (EC) No 852/2004. An interruption of the cold chain is also a typical route of microbial growth that interacts with cross-contamination: temperature and separation are the two basic defences against biological hazards.
Common errors
- Citing a single "legal temperature" for all food. Regulation 852/2004 sets no numeric value: it requires that temperature not result in a risk Annex II, Chapter IX, point 5 of Regulation (EC) No 852/2004. Values by category are in Regulation 853/2004 Article 3 of Regulation (EC) No 853/2004 and in national rules.
- Reading the derogations as freedom to break the cold chain. The derogation applies only for "limited periods", for practical needs and without a health risk Annex II, Chapter IX, point 5 of Regulation (EC) No 852/2004: it does not legitimise prolonged holding at ambient temperature.
- Neglecting rapid cooling after cooking. Point 6 requires cooling as quickly as possible after heat processing or final preparation Annex II, Chapter IX, point 6 of Regulation (EC) No 852/2004: letting food cool slowly at room temperature is a frequent non-compliance.
Frequently asked questions
What does Regulation 852/2004 say about the cold chain?
That food supporting the growth of pathogens or the formation of toxins must not be kept at temperatures that might result in a risk to health and that the cold chain must not be interrupted, save for limited periods Annex II, Chapter IX, point 5 of Regulation (EC) No 852/2004.
Does the regulation set refrigerator temperatures?
No. Regulation 852/2004 uses an outcome standard ("temperatures that would not result in a risk") Annex II, Chapter IX, point 5 of Regulation (EC) No 852/2004. Numeric temperatures by category come from Regulation 853/2004 for products of animal origin Article 3 of Regulation (EC) No 853/2004 and from national rules.
Can the cold chain be interrupted?
Only for limited periods and for the practicalities of preparation, transport, storage, display and service, without any resulting risk to health Annex II, Chapter IX, point 5 of Regulation (EC) No 852/2004. A prolonged or unjustified interruption is not allowed.
How must cooked food to be held chilled be cooled?
As quickly as possible after heat processing or the final preparation stage, to a temperature that does not result in a risk Annex II, Chapter IX, point 6 of Regulation (EC) No 852/2004. It is the basis for rapid blast chilling.
Does the cold chain apply to transport too?
Yes. Chapter IV of Annex II requires that transport compartments and containers keep food at an appropriate temperature and, where necessary, allow it to be monitored Annex II, Chapter IV, point 7 of Regulation (EC) No 852/2004.
Is the cold chain a CCP in HACCP?
Often yes, or an operational prerequisite. Storage temperature control is typically monitored through records in the HACCP system Article 5(2) of Regulation (EC) No 852/2004; the choice depends on the hazard analysis of the individual activity.
