There is no single temperature that is correct for every food. The requirement may come from product-specific law, the manufacturer's label, a supplier specification or the site's HACCP analysis.
In short: always apply the strictest relevant requirement for the product. Do not set an entire room from a simplified internet table.
Examples from EU requirements
Regulation (EC) No 853/2004 contains detailed temperatures for certain foods of animal origin. Examples include:
| Product | Example requirement |
|---|---|
| Fresh red meat | No more than +7°C |
| Offal | No more than +3°C |
| Poultry | No more than +4°C |
| Minced meat | No more than +2°C |
| Meat preparations | No more than +4°C |
| Fresh fishery products | A temperature approaching that of melting ice |
| Quick-frozen food | Generally −18°C or colder |
These figures apply within defined scopes. They do not replace the label or the site's procedure. Requirements for dairy, prepared food and produce depend on the exact product and manufacturer information.
How do you set the correct limit?
Check, in order:
- Law for the product category and the relevant stage of production or distribution.
- The label and manufacturer specification, including conditions after opening.
- Customer or contract requirements, if they are stricter.
- The HACCP hazard analysis, including time, packaging and further processing.
- Measurement uncertainty and normal room variation, so the controller setting leaves a sensible margin.
The controller setpoint is not automatically the product limit. Its sensor controls the unit at one location, while food temperature changes more slowly than air temperature. The procedure should distinguish the setpoint, alarm threshold and product limit that triggers an assessment.
The familiar “danger zone” of 5–63°C and the four-hour rule can be useful training concepts, but they are not one universal EU legal limit for every food. A deviation assessment must consider the actual product temperature, duration, food type and approved procedure.
What should you do after a breach?
- record the detection time and reading;
- confirm the result with another suitable instrument;
- limit door openings and stop adding warm product;
- establish how long the batch may have been outside its range;
- isolate the stock until a responsible person decides its status;
- follow the HACCP action, such as transfer, further assessment, treatment, return or disposal;
- remove the cause and record every action.
Do not release food simply because the room air has returned to the setpoint.
