Washing & sanitation protocols

Here’s a professional, TESDA-aligned, field-ready module on Washing & Sanitation Protocols for Agarwood Leaf Tea, focusing on food-grade, non-resin leaves, and integrating GMP, hygiene, and traceability practices.


Washing & Sanitation Protocols

Food-Grade Agarwood Leaf Tea Production


1. Core Principle

“Clean leaves, safe tea.”

Proper washing and sanitation prevent microbial contamination, chemical residues, and cross-contamination, ensuring food-grade quality and regulatory compliance.


2. When to Wash Leaves

  • Optional, only if leaves are visibly dirty or dusty
  • Avoid washing if leaves are clean and dry, mature, and harvested in hygienic conditions
  • Never wash leaves post-drying

Principle: Minimize water contact to prevent microbial growth and nutrient loss


3. Washing Protocol

Stepwise Procedure for Pre-Drying Leaf Washing:

  1. Preparation
    • Use clean, potable water
    • Prepare sanitized washing trays or tanks
  2. Immersion or Rinse
    • Lightly immerse leaves or gently rinse under flowing water
    • Avoid prolonged soaking to prevent loss of bioactive compounds
  3. Agitation
    • Gently move leaves with clean hands or sanitized tools
    • Remove visible dust, debris, and insects
  4. Draining
    • Use sanitized sieves or trays for draining excess water
    • Avoid pooling water at the bottom
  5. Air Drying
    • Place leaves on sanitized drying racks
    • Ensure adequate airflow, avoid stacking

4. Sanitation of Facilities & Equipment

ComponentSanitation Practice
Washing trays / tanksRinse, scrub, disinfect with food-safe sanitizer
Tools (scissors, knives)Wash, rinse, sanitize before and after use
Drying racksSweep, wipe, disinfect periodically
Storage containersWash, dry, store off-floor and away from dust
Worker hygieneWash hands, gloves, aprons before handling leaves

Daily or per-harvest sanitation is recommended.


5. Water Quality Considerations

  • Potable water only
  • Check microbial contamination periodically
  • Avoid stagnant or untreated water sources

Using clean water reduces risk of mycotoxins, microbial growth, and chemical residues.


6. Integration with Traceability & GMP

  • Record batch number for every washed lot
  • Maintain harvest logs noting washing date, personnel, and water source
  • Sanitation records support GMP audits and food safety compliance

7. TESDA-Aligned Learning Outcomes

Learners will be able to:

  1. Identify when washing is necessary for agarwood leaves
  2. Apply proper washing techniques for food-grade leaves
  3. Sanitize tools, trays, and drying racks effectively
  4. Record washing and sanitation activities for traceability
  5. Maintain food-grade compliance for export and domestic markets

8. Regulatory References

  • FDA-PH Food Safety Guidelines: Washing, sanitation, traceability
  • BFAD Legacy Circulars: Herbal leaf processing and hygiene
  • Codex Alimentarius / ASEAN Standards: Food handling, microbial safety

9. Training Disclaimer

This module applies exclusively to food-grade agarwood leaves.
Resin and heartwood are non-food parts and follow separate processing and regulatory pathways.


✅ Ideal For:

  • TESDA CBLM & field training modules
  • Oud Academia food safety and hygiene courses
  • Plantation SOPs and audit-ready documentation
  • Export-ready herbal tea preparation

I can next create:

  1. A visual infographic of washing & sanitation workflow
  2. A fillable field checklist for sanitation activities
  3. Integration with traceability, batch coding, and GMP modules
