How often should the manager or employees conduct a self-inspection to evaluate the effectiveness…

➤ When should inspections be documented and how long should records be kept?
Document each self-inspection immediately using a checklist, date, time, and responsible person. Record findings, measurements (ATP, swabs, concentration), and corrective actions with completion dates. Keep records according to regulatory and company policy—commonly one to three years for food and healthcare systems—to support audits, traceability, and continuous improvement.
