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

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

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

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

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

Auditor Verification Checklist

During a BRCGS audit, be prepared to show:

  • A documented list of validated processes and rationale

    Scientific, technical, or practical validation records

    Evidence of revalidation after significant changes

    Verification and monitoring records supporting ongoing control

Implementation Roadmap

Identify & Prioritize

  • Review all processes for hazard control impact

    Determine which require formal validation

Validate & Record

  • Conduct scientific or in-plant validation studies

    Document protocol, data, results, and approvals

Monitor & Maintain

  • Train staff on validated process parameters

    Verify ongoing process compliance during operations

Revalidate & Improve

  • Review process controls annually or after any change

    Update validation documentation as needed

Why This Matters?

  • Demonstrates scientific confidence in your process controls

    Reduces risk of relying on finished product testing

    Supports audit and regulatory expectations under BRCGS Clause 5.3

    Prevents costly recalls, non-conformities, or product withdrawals
