Audit Trail

An audit trail is a chronological record of actions, observations, decisions and changes that allows a business to reconstruct what happened and who was responsible. In foodservice, an audit trail supports food-safety verification, traceability, accountability and investigation of incidents or deviations.

What a food-safety audit trail may include

• Monitoring records: receiving temperatures, cooking and cooling logs, refrigeration checks and sanitizer verification.
• Corrective actions: the deviation, immediate response, affected food, responsible employee and follow-up verification.
• Traceability: supplier details, lot codes, harvest information and product movement where required.
• Training and competency: staff training records, certificates and documented assessments.
• Equipment and maintenance: calibration, repair and service records for equipment that affects food safety.
• Digital changes: user, date, time and details of edits to electronic logs, recipes or compliance records when the system supports it.

Example: cooling deviation

If a batch of chili does not cool within the limits in the operation’s food-safety plan, the record should identify the batch, time and temperature readings, the person who discovered the deviation, the corrective action taken, the disposition of the food and the person who verified the outcome. This creates a traceable history for management and inspectors.

Audit trail versus checklist

A checklist is a tool for completing or verifying tasks. An audit trail is the broader record of what occurred, including results, decisions, corrections and changes over time. A checklist can form part of an audit trail when it is completed, retained and linked to the relevant process.

Chef’s tip: make records contemporaneous, legible and specific. Corrections should preserve the original entry and show who made the change and when, according to the recordkeeping system and applicable requirements.
