Process Control: Process Validation
Aligned with BRCGS Food Safety Issue 9 – Clause 5.3
Requirement Overview
BRCGS Food Safety Issue 9 requires that all processes essential to the production of safe and legal food—especially those that cannot be fully verified through inspection or testing—must be validated to demonstrate that they effectively achieve the intended food safety outcome.
Clause 5.3.1: “The company shall validate processes to ensure they achieve the required food safety outcomes. Validation shall be carried out when the process is first developed or changed.”
Validation confirms that a process (e.g., cooking, cooling, metal detection, or chemical sanitation) consistently delivers the necessary control to eliminate or reduce hazards to acceptable levels.
Aligned with BRCGS for Storage & Distribution Issue 4 – Clause 4.3.1 & 4.3.3
Requirement Overview
BRCGS for Storage & Distribution requires that products moved via cross-docking are traceable and controlled at all times, even when they are not held in storage for extended periods.
Clause 4.3.1: “The company shall ensure that traceability is maintained at all stages, including during cross-docking operations.”
Clause 4.3.3: “Procedures shall be in place to ensure that all products handled, including those not stored on-site, remain under control and are not subject to contamination or substitution.”
Cross-docking operations must not compromise product traceability, safety, or integrity. Even with minimal handling and temporary presence, each product must be accurately identified, documented, and protected.
Key Compliance Objectives
-
✓ Confirm that critical control processes deliver intended food safety results
✓ Prevent reliance on final product testing alone
✓ Maintain scientific or technical evidence for each validated step
✓ Ensure compliance during new product launches, process changes, or equipment upgrades
Step-by-Step Compliance Implementation
1. Identify Processes Requiring Validation
-
Examples Include:
-
• Thermal processing (e.g., cooking, pasteurization, sterilization)
• Cooling or chilling steps
• Chemical or physical decontamination processes
• Metal detection, x-ray, or sieving
• Modified atmosphere packaging (MAP) or vacuum sealing
Evidence to Maintain:
-
• List of validated processes
• Associated CCPs and preventive controls
• Process flow diagram with identified validation points
- • Thermal processing (e.g., cooking, pasteurization, sterilization) • Cooling or chilling steps • Chemical or physical decontamination processes • Metal detection, x-ray, or sieving • Modified atmosphere packaging (MAP) or vacuum sealing
- • List of validated processes • Associated CCPs and preventive controls • Process flow diagram with identified validation points
2. Conduct Initial Validation
-
Validation Activities May Include:
-
• Laboratory testing (e.g., microbial challenge studies)
• Literature or scientific references supporting process effectiveness
• In-plant trials and test runs under real operating conditions
• Third-party studies or equipment manufacturer data
Evidence to Maintain:
-
• Process validation protocol and summary report
• Test data, results, and supporting references
• Approval records by QA, Technical, or Food Safety Team
- • Laboratory testing (e.g., microbial challenge studies) • Literature or scientific references supporting process effectiveness • In-plant trials and test runs under real operating conditions • Third-party studies or equipment manufacturer data
- • Process validation protocol and summary report • Test data, results, and supporting references • Approval records by QA, Technical, or Food Safety Team
3. Revalidate After Changes
-
Trigger Events Include:
-
• Change in ingredients, packaging, or product formulation
• Equipment upgrades or relocation
• Alteration of processing parameters (e.g., time, temperature, pressure)
• Introduction of new regulatory or customer requirements
Evidence to Maintain:
-
• Change control form with justification
• Updated validation report
• Internal approval documentation
- • Change in ingredients, packaging, or product formulation • Equipment upgrades or relocation • Alteration of processing parameters (e.g., time, temperature, pressure) • Introduction of new regulatory or customer requirements
- • Change control form with justification • Updated validation report • Internal approval documentation
4. Train and Monitor Teams
-
Control Measures:
-
• Ensure operators understand validated critical limits
• Include process validation details in CCP and OPRP monitoring procedures
• Periodically verify implementation against validated conditions
Evidence to Maintain:
-
• Training records specific to validated processes
• CCP monitoring logs
• Internal audit findings and follow-up
- • Ensure operators understand validated critical limits • Include process validation details in CCP and OPRP monitoring procedures • Periodically verify implementation against validated conditions
- • Training records specific to validated processes • CCP monitoring logs • Internal audit findings and follow-up
Common Audit Findings & Recommended Fixes
| Audit Finding | Recommended Action |
|---|---|
| No documented process validation | Conduct and retain validation protocols and scientific justification |
| Outdated validation after equipment change | Revalidate and document after process modifications |
| Reliance on finished product testing only | Use proactive process validation instead of reactive testing |
| Inadequate evidence or unsupported claims | Use credible references, lab tests, or qualified third-party data |
