Site Standards: Layout, Product Flow & Segregation
Aligned with BRCGS Food Safety Issue 9 – Clause 4.3
Requirement Overview
BRCGS Food Safety Issue 9, Clause 4.3 requires that the facility’s layout and operational flow minimize the risk of product contamination. There must be logical, controlled movement of materials, personnel, waste, and finished goods to ensure hygiene zoning, segregation, and product integrity.
Clause 4.3.1: “The process flow, building layout, and product handling procedures shall be designed, documented, and maintained to prevent contamination, cross-contact, and mix-ups.”
Effective layout and segregation are foundational to reducing food safety hazards such as cross-contamination, allergen contact, and foreign material intrusion.
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
-
✓ Ensure physical separation of raw and finished product zones
✓ Maintain hygienic product flow that supports food safety
✓ Prevent cross-contamination through personnel and material movement controls
✓ Document and monitor flow procedures and zoning standards
Step-by-Step Compliance Implementation
1. Design and Maintain Logical Site Layout
-
Key Actions Include:
-
• Define raw, in-process, and finished product areas
• Designate hygiene zones and traffic flow routes
• Identify high-risk and low-risk processing zones
Evidence to Maintain:
-
• Site layout map with zoning and flow markings
• Floor plan with process flow arrows
• Zoning protocol documentation
- • Define raw, in-process, and finished product areas • Designate hygiene zones and traffic flow routes • Identify high-risk and low-risk processing zones
- • Site layout map with zoning and flow markings • Floor plan with process flow arrows • Zoning protocol documentation
2. Control Movement of People and Materials
-
Flow Controls May Include:
-
• Color-coded uniforms or PPE by zone
• Designated walkways, barriers, or controlled access points
• Sanitation stations at entry/exit to critical zones
Evidence to Maintain:
-
• Zoning and flow training records
• PPE usage logs and color-code guides
• Access control or visitor entry protocols
- • Color-coded uniforms or PPE by zone • Designated walkways, barriers, or controlled access points • Sanitation stations at entry/exit to critical zones
- • Zoning and flow training records • PPE usage logs and color-code guides • Access control or visitor entry protocols
3. Implement Product and Waste Segregation
-
Segregation Requirements:
-
• Physical or procedural separation of allergen and non-allergen products
• Dedicated lines, tools, or schedules for sensitive products
• Clearly defined waste disposal paths to prevent contamination
Evidence to Maintain:
-
• Allergen segregation matrix or cleaning validation records
• Line clearance and changeover procedures
• Waste flow documentation and handling logs
- • Physical or procedural separation of allergen and non-allergen products • Dedicated lines, tools, or schedules for sensitive products • Clearly defined waste disposal paths to prevent contamination
- • Allergen segregation matrix or cleaning validation records • Line clearance and changeover procedures • Waste flow documentation and handling logs
4. Monitor, Review & Update Flow and Layout
-
Verification Activities:
-
• Routine inspections of site compliance with zoning rules
• Internal audits of personnel and material movement practices
• Layout updates based on equipment changes or risk reviews
Evidence to Maintain:
-
• Completed zoning inspections and checklists
• Audit findings and corrective action records
• Updated layout drawings or flow diagrams
- • Routine inspections of site compliance with zoning rules • Internal audits of personnel and material movement practices • Layout updates based on equipment changes or risk reviews
- • Completed zoning inspections and checklists • Audit findings and corrective action records • Updated layout drawings or flow diagrams
Common Audit Findings & Recommended Fixes
| Audit Finding | Recommended Action |
|---|---|
| No zoning or poor layout planning | Develop and post updated process flow diagrams and zoning maps |
| Cross-contamination between raw and cooked zones | Introduce physical barriers or revise material handling procedures |
| Personnel moving between zones without control | Reinforce hygiene zoning protocols and PPE requirements |
| Poor allergen segregation | Implement dedicated allergen handling procedures and verification |
