Risk‑Based Cleaning Validation: Harmonising Global Guidelines

With regulators around the world converging on risk‑based cleaning validation protocol standards, global compliance is both a strategic necessity and a formidable challenge. EMA now mandates Health-Based Exposure Limits (HBELs), the FDA stresses continuous improvement with ongoing acceptance for visual inspection, and agencies like MHRA, ANVISA, and PIC/S introduce localized and lifecycle-specific demands.

For pharma QA, QC, and validation professionals, harmonizing these expectations into a unified, science-driven cleaning validation program is critical for audit readiness, patient safety, and operational efficiency.

The Global Shift: Risk-Based Cleaning Validation Across Agencies

EMA – Setting the Pace with HBELs and Lifecycle Revalidation

EMA (European Medicines Agency) enforces cleaning validation protocols that derive residue limits primarily from HBELs, using toxicological and pharmacological data.

• Revalidation is explicitly required throughout the product lifecycle, particularly after equipment, product, or process changes.
• Visual inspection alone is not sufficient; residue limits must be documented quantitatively with traceable digital records.

FDA – Flexibility with a Focus on Continuous Improvement

FDA (U.S. Food and Drug Administration) allows visual inspection as part of acceptance criteria but leans on scientifically justified, risk-based protocols.

• Continuous improvement is emphasized—cleaning protocols must include rationale for analytical methods and sampling, ongoing monitoring, and revalidation triggers.
• Digital audit trails and automated records are strongly encouraged. Learn more in our SOP for Cleaning Validation.

MHRA – Digital Records and Enhanced Risk Assessment

MHRA (UK) requires enhanced risk assessment, integrated traceability, and frequent personnel training.

• Digital record-keeping systems are expected—handwritten logs or manual documentation are considered high risk.
• Clear ownership and role assignment are essential for validation execution.

ANVISA – Localized Risk Assessments and Trigger-Based Revalidation

ANVISA (Brazil) follows PIC/S and WHO fundamentals but includes region-specific GMP formatting.

• Validation must consider local manufacturing practices.
• Revalidation is triggered after any significant change to product, process, or equipment.

PIC/S – Worst‑Case Validation and Lifecycle Management

PIC/S calls for:

• Worst‑case product and equipment selection
• Validated analytical methods
• A fully documented lifecycle from equipment qualification to process monitoring

Building a Harmonised, Risk‑Based Cleaning Validation Protocol

1. Conduct a Formal Risk Assessment
   Begin with a comprehensive evaluation of product toxicity, dose, batch size, and cleaning agent characteristics.
   • Identify worst‑case scenarios.
   • Follow HBEL-driven residue limit principles, moving away from outdated “10 ppm” criteria.
2. Align Documentation Across Agencies
   • Use MACO/HBEL calculations to define acceptance criteria.
   • Combine visual inspection (as permitted by FDA) with quantitative thresholds (as required by EMA).
   • Clearly map regulatory references and assumptions.
3. Leverage Digital Record-Keeping and Automation
   • Implement automated audit trails, electronic signatures, and deviation logging systems.
   • Agencies like MHRA and PIC/S expect validated digital platforms.
   • Platforms like CLEEN streamline this with compliant templates, real-time updates, and trend dashboards.
   Pro Tip: CLEEN’s automation ensures site-specific compliance, auto-revalidates after any process change, and provides a single system of record—all features sought by agencies like MHRA and ANVISA.
4. Train Cross-Functional Teams
   • Train QA, QC, manufacturing, and engineering on risk‑based cleaning validation principles, digital workflows, and lifecycle management.
   • Continuous and role-specific training ensures sustained audit-readiness.
5. Continuously Re‑Assess Risks and Revalidate
   • Update HBELs, sampling plans, and cleaning methods regularly or after trigger events.
   • Use trending tools and statistical dashboards for real-time verification.
   • This aligns with EMA, ANVISA, and PIC/S expectations for lifecycle validatio

Operationalizing a Unified Global Cleaning Validation Strategy

Key Steps for Global Compliance

• Standardize risk assessments using HBEL and worst-case logic across all sites.
• Align documentation—protocols, SOPs, sampling plans—against EMA, FDA, MHRA, ANVISA, and PIC/S expectations.
• Digitize all workflows to ensure transparency, data integrity, and audit readiness.
• Automate audit-trails and revalidation triggers to prevent manual oversight.
• Embed continuous training and ownership into your operations.

Pro Tip: CLEEN integrates LIMS data, risk scores, and audit logs for seamless, multinational compliance—making it easy to defend your cleaning validation program to any agency, anywhere.
