Fridge and freezer temperature monitoring: what HACCP requires

The rule-of-thumb limits are clear: chilled food up to +5 °C, frozen −18 °C or below, hot holding above +60 °C. And how often should you measure? Manually, at least twice a day per unit in practice — an automatic system measures continuously 24/7 and creates the records by itself. Below is what applies to fridges, freezers and food storage, and how to prove compliance at an inspection.

Which temperatures you have to keep

The exact values depend on the food type and your HACCP plan, but as a rule of thumb:

• Chilled food: usually up to +5 °C (meat, dairy, deli).
• Frozen food: −18 °C and below.
• Hot food on service: above +60 °C.

The limits stem from EU Regulation (EC) No 852/2004 on food hygiene and the national rules that build on it — the exact values for your operation come from your HACCP analysis.

Temperature in food storage rooms

Storage is the point HACCP plans forget most often — yet a dry store and a cellar have limits just like a fridge. As a rule of thumb: a dry store (flour, rice, canned goods, packaging) usually up to +18 °C, a vegetable cellar around +5 to +10 °C. The exact values, again, come from your HACCP plan.

In storage, temperature isn't the only factor. Humidity above 65 % means mould, damp dry goods and ruined packaging — which is why storage rooms are monitored for humidity alongside temperature. The same system that watches your fridges handles both.

How often temperature should be measured

No regulation gives an exact number — you set the frequency in your own HACCP plan. In practice, manual measurement means at least twice a day per unit (morning and evening); temperature is typically checked daily — at goods receipt, during storage and at service. At an inspection, however, the officer wants to see records without gaps — weekends, holidays and nights included. An automatic system measures continuously 24/7, evaluates every value against your limits and creates HACCP records as PDFs by itself. The "how often" question disappears: there is a record for every minute of operation.

Why paper logs aren't enough

Manual records get forgotten, filled in after the fact, and don't look credible at a food-safety inspection. They also miss short spikes — a failed compressor at night is only discovered in the morning, when the stock is already gone.

Automatic temperature monitoring as the answer

A probe in the cooling unit measures continuously, data goes to the cloud and HACCP records are created on their own. If a limit is exceeded, an instant alert reaches your phone, so you can react before the stock suffers. How automatic temperature monitoring works →
