What HACCP requires today
HACCP is not a voluntary quality initiative – for more than two decades it has been mandatory for every food-business operator in the EU, from the bakery around the corner to industrial food production. EU Food Hygiene Regulation (EC) 852/2004 is the central legal basis; the German LFGB transposes the requirements into national law and the LMHV regulates the detailed requirements. Inspection practice differs by federal state, responsible veterinary office and the risk classification of the business.
Data points – what the logging must capture
Every critical control point has assigned data points that are logged continuously: air temperature (calibrated), set-point temperature per LMHV, plant status, area identification and time stamp. The air temperature is measured with a calibrated sensor at a representative height and position – in large cold rooms at several measuring points. In high-risk refrigeration areas recording is often at one-minute intervals, in less critical areas every 5 to 15 minutes.
Tamper-proof data storage
Once recorded, the data can no longer be changed; corrections are only possible as additional entries with a complete change history. The BMS stores the HACCP records in an append-only database, keeps them redundantly on at least two independent storage media, documents every configuration change with time stamp, user, old and new value, and additionally secures data integrity with cryptographic checksums.
Alarm chain – local, escalation, automatic logging
An HACCP-relevant temperature deviation triggers three parallel consequences: directly at the refrigerated area an optical and acoustic signal is raised that stays active until acknowledged – the acknowledgement is documented in the activity log. In parallel the BMS sends messages to the service and on-call structure, depending on time of day and weekday and via redundant channels (e-mail, SMS, messaging). The automatic HACCP entry is made at the same time – with set point, actual value, start, end and the measure taken.
Planned exceptions – defrost phases, maintenance, cleaning, deliveries
Every refrigeration plant has planned operating phases in which the set-point temperature cannot be maintained for a short time: defrost phases, maintenance visits, cleaning routines, deliveries with the door open for longer. The BMS marks them as planned exceptions – with start, end and responsible person – and cleanly separates them from unplanned deviations. If a phase lasts unusually long, the system switches back to normal alarm mode so that defects cannot hide behind the defrost disguise.
Inspection practice – how the veterinary office and food-safety authority proceed
Inspections are usually unannounced and follow a structured choreography: walk-through, document request, spot checks of the temperature histories, staff interviews, follow-up of corrective actions, report. BMS-based HACCP documentation delivers the requested periods at the push of a button in an inspection-ready format – tables, histories, exception documentation – within minutes instead of hours.
