Why temperature monitoring matters in a cafe
Temperature control is the primary mechanism for preventing the growth of foodborne pathogens in a food service environment. Salmonella, Campylobacter, Listeria, Clostridium perfringens, and Staphylococcus aureus — the pathogens most commonly associated with cafe food poisoning incidents — all have defined temperature ranges within which they grow, and temperatures outside those ranges at which growth is inhibited or the organism is killed.
The purpose of temperature monitoring is to provide documented evidence that the temperature control measures in your HACCP plan are actually working — that cold food is staying cold, hot food is staying hot, and cooked food is reaching the temperature required to kill pathogens.
Temperature monitoring requirements for a typical Sydney cafe
| What to Monitor | Critical Limit | How Often | Tool |
|---|---|---|---|
| Refrigeration units (display fridge, prep fridge, coolroom) | ≤5°C | Minimum twice daily | Calibrated probe thermometer or datalogger |
| Cooked poultry and eggs | ≥75°C core temperature | Every cooking batch | Calibrated thermocouple probe |
| Cooling batch-cooked food (2-hour check) | ≤21°C within 2 hours from 60°C | Per cooling batch | Calibrated probe thermometer |
| Hot holding (bain-marie, heat lamp) | ≥60°C throughout | At start of service + hourly | Calibrated probe thermometer |
| Incoming deliveries (chilled) | ≤5°C on arrival | Every chilled delivery | Calibrated probe thermometer |
Probe thermometer calibration — the step most cafes miss
A probe thermometer that has not been calibrated recently is unreliable for CCP monitoring — you cannot trust the readings. Weekly ice slurry calibration (0°C ± 0.5°C) takes less than one minute and provides documented evidence that your monitoring equipment is accurate. Any monitoring results taken with an out-of-calibration thermometer may be considered invalid during a NSW Food Authority audit.
