Maintain Clear Segregation Between Different Product Families in GMP

Ensure Proper Segregation of Different Product Families in GMP Facilities

Remember: Different product families must be physically and procedurally segregated during manufacturing and storage to prevent mix-ups and cross-contamination.

Why This Matters in GMP

Pharmaceutical facilities often produce multiple product types, such as tablets, injectables, or hormone-based therapies. Each category may differ in potency, stability, or allergenic potential. Cross-contact between such product families can compromise patient safety, especially in sensitive populations. GMP mandates physical, procedural, and documentation-based segregation of product lines. This includes dedicated equipment, cleaning validation, and controlled scheduling. Failure to segregate products may result in cross-contamination, label mix-ups, or misbranded drugs. Effective segregation enhances traceability, reduces deviation risk, and ensures product integrity throughout the lifecycle.

Regulatory and Compliance Implications

FDA 21 CFR Part 211.42 and 211.89 require separation of products and prevention of cross-contamination. EU GMP Chapter 3 and Chapter 5 outline strict requirements for dedicated areas and line clearance. WHO GMP and Schedule M mandate risk-based segregation depending on the product’s classification. Auditors inspect facility layouts, material flows, equipment usage logs, and cleaning validations. Lack of clear segregation can result in critical observations, enforcement actions, and even recalls. Documentation must clearly support that each product is handled in isolation or through validated shared processes.

Implementation Best Practices

Classify products by risk category (e.g., beta-lactams, cytotoxics, hormones, general solids).
Use color-coded zones, dedicated equipment, and separate HVAC lines for high-risk products.
Schedule production campaigns to avoid overlap of conflicting product families.
Maintain cleaning validation records that demonstrate effective removal of residues.
Train operators on product-specific SOPs and area access restrictions.
