Process Control: Process Validation

Aligned with FSSC 22000 Requirements

Requirement Overview

FSSC 22000 requires that all processes essential to the production of safe and compliant food—particularly those that cannot be fully verified through inspection or testing—are validated to demonstrate that they consistently achieve the intended food safety outcome.

Validation confirms that a process (such as cooking, cooling, chemical sanitation, or metal detection) can reliably control identified hazards to an acceptable level under actual operating conditions.

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 consistently deliver the intended food safety results

    Avoid over-reliance on finished product testing

    Maintain scientific or technical evidence supporting each validated step

    Ensure validation is conducted for new processes, product launches, or process changes

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 diagrams with validation points identified

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 normal operating conditions

      Third-party studies or manufacturer performance data

    Evidence to Maintain:

    • Process validation protocol and summary report

      Test data, results, and supporting references

      Approval records from the Food Safety Team or relevant technical authority

3. Revalidate After Changes

  • Trigger events include:

    • Change in ingredients, packaging, or formulation

      Equipment upgrades, replacements, or relocation

      Alteration of processing parameters (time, temperature, pressure)

      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 include:

    • Ensuring operators understand validated critical limits

      Including validation details in CCP and OPRP monitoring procedures

      Periodically verifying process performance against validated parameters

    Evidence to Maintain:

    • Training records specific to validated processes

      CCP and OPRP monitoring logs

      Internal audit findings and follow-up actions

Common Audit Findings & Recommended Fixes

Audit Finding Recommended Action
No documented process validation Conduct and retain validation protocols with scientific justification
Outdated validation after equipment or process changes Revalidate promptly and document changes
Reliance solely on finished product testing Use proactive process validation to ensure control effectiveness
Insufficient evidence or unsupported claims Use credible references, laboratory testing, or qualified third-party data

Auditor Verification Checklist

During an FSSC 22000 audit, be prepared to provide:

  • A documented list of validated processes with justification

    Scientific, technical, or practical evidence of validation

    Records of revalidation after significant changes

    Monitoring and verification records confirming ongoing compliance

Implementation Roadmap

Identify & Prioritize

  • Review processes for hazard control significance

    Determine which require formal validation

Validate & Record

  • Conduct scientific or in-plant validation studies

    Document protocols, data, results, and approvals

Monitor & Maintain

  • Train staff on validated process parameters

    Verify compliance during routine operations

Revalidate & Improve

  • Review process controls annually or after any change

    Update validation documentation as needed

Why This Matters?

  • Demonstrates scientific confidence in process controls

    Reduces risk by ensuring hazard control before product release

    Supports audit and regulatory compliance under FSSC 22000

    Prevents costly recalls, non-conformities, or withdrawals
