Due Diligence

Due diligence in food service means taking reasonable, practical steps to prevent food-safety problems and demonstrate that a business has managed its responsibilities. It includes having suitable procedures, training staff, monitoring critical activities, correcting problems and keeping accurate records. The exact legal meaning and requirements depend on the jurisdiction and circumstances.

Examples of due diligence in a restaurant

• Staff training: provide required food-safety training and keep competency and certification records.
• Temperature control: monitor receiving, cooking, cooling, cold holding and hot holding according to the food-safety plan.
• Supplier approval: purchase from suitable suppliers and retain product specifications and traceability information.
• Cleaning and sanitation: maintain schedules, chemical specifications, sanitizer checks and verification records.
• Allergen management: maintain current recipes and ingredient labels, train staff and control cross-contact.
• Corrective action: document deviations, product disposition and steps taken to prevent recurrence.

Due diligence versus having a written policy

A written procedure is only one part of due diligence. The business must put it into practice, train employees, monitor whether it works and respond when standards are not met. A completed checklist that does not reflect actual practice is not a reliable control.

Records and evidence

Useful records may include training logs, temperature charts, receiving checks, cleaning records, equipment maintenance, supplier documentation, pest-control reports and corrective-action logs. Records should be accurate, completed at the time of the activity and retained according to applicable requirements.

Chef’s tip: Make food-safety controls practical enough for staff to follow during service. Assign clear responsibility, verify completion and investigate repeated failures rather than simply filing the paperwork.

Key distinction: Due diligence is the reasonable action taken and demonstrated by a business; it is not guaranteed immunity from liability or a substitute for meeting legal requirements.
