Top 10: What Food Safety Managers should be monitoring

Here are 10 key elements that we believe Food Safety Managers should be monitoring in their refrigeration fleet while using AoFrio IoT solutions.

These actions help you to detect issues early, act quickly, and maintain a complete audit trail for inspections and HACCP.

  1. Ensure product temperature compliance (HACCP): Set temperature alerts and monitor performance trends in your refrigeration assets to prevent pathogen growth and food spoilage.
  2. Monitor door openings and ‘dwell time’: Prolonged or frequent openings in your chilled and frozen assets can negatively impact temperature and increases energy use within the cooler. By monitoring this you can reduce your energy bill and maintain ideal temperature for your inventory.
  3. Check temperature recovery after door opening and stocking: If your cooler is slow to recover the optimal temperature after restocking, this can signal overloading, poor airflow, or other equipment issues.
  4. Act on power status and outages: Loss of power quickly leads to unsafe temperatures. Keeping track of outage events can save food from spoilage and improve stocking choices.
  5. Set defrost cycles to maintain temperature stability: Faulty or excessive defrosts can impact temperature stability which, in turn, may spoil delicate foods and creates ice buildup within your refrigerators.
  6. Monitor the health of components within your equipment: By monitoring compressor and fan behavior (e.g. checking for excessive or short cycling, extended run times and unusual temperature patterns) you can detect critical faults early to prevent stock loss and asset downtime caused by equipment failure.
  7. Be aware of ambient conditions around the cooler: High ambient temperatures around the cooler (e.g. direct sunlight via a nearby window, proximity to hot food preparation areas) can reduce cooling efficiency and raise overall food risk.
  8. Check data continuity and last check-in dates: Gaps your data can hide risk and weaken your audit readiness.
  9. Provide installation training to improve sensor placement: Misplaced sensors (or ones that have run out of battery) often lead to false confidence or nuisance alerts.
  10. Work on your alert acknowledgment and resolution times: This demonstrates control in your audit trail and improves the turnaround times for corrective actions.
