Why post-harvest is route-critical
The batch risk profile can change after harvest. Poor drying conditions can increase microbial risk, weak storage can damage identity and informal access can undermine chain of custody.
Buyers need to know the material was controlled after harvest, not just grown well.
What to record
Drying and storage evidence should connect environment, material and people.
- Room ID, batch ID and material movement times.
- Temperature, humidity and relevant condition logs.
- Cleaning status before use and between batches.
- Access control and personnel entries for critical rooms.
- Yield reconciliation from wet weight through dry/trimmed output.
- Excursions, alarms, deviations and batch impact decisions.
Feasibility reading
Ready means the farm can show continuous control. Conditional means monitoring exists but gaps need explanation. Blocked means post-harvest identity or condition control cannot be reconstructed.
GACP/GMP feasibility check
Drying and storage records protect batch identity and condition history.
Evidence: Room logs, condition logs, cleaning records, movement records, deviation log.
Monitoring exists but has missing intervals or no excursion decision rule.
Evidence: Gap review, excursion SOP and retrospective impact assessment.
Downstream medicinal route requires defined acceptance criteria for post-harvest controls.
Evidence: Buyer specification, importer review and technical agreement.
