Many business's are using technology now, with thermocouples transmitting the temperature of fridges and freezers continuously, and have an alert or alarm system.
Victoria's Department of Health has released a guideline to manage the alternative system on monitoring temperature, to ensure your system is accurate and reliable in its readings, and alerts.
The guidance information can be accessed here.
The system you choose must:
- monitor and report twice daily temperature readings (at a minimum)
- trigger an alarm when a storage unit is not holding food within the set temperature limits
- document corrective actions that were taken when temperature control issues occur
- have a thermocouple accuracy of ±1 °C
- be validated so that it produces consistently accurate results
- be calibrated each year (thermocouples and alarms)
- have a maintenance program in place to ensure continuous operation of the system
