Testing Before and After Fermentation

Testing · evidence for hold-and-release decisions

Testing should answer specific release questions, not produce data for its own sake. A good plan defines what to test, when to test, and how results drive action.

Test Stage	Typical Purpose	Decision Use
Incoming materials	Confirm supplier/lot status	Accept, quarantine, or reject lot
In-process checkpoints	Verify control effectiveness	Continue, re-clean, or adjust process
Finished batch	Confirm claim and quality targets	Release or hold batch

---

Testing strategy mistakes:

• Testing too late to prevent release risk
• Missing chain-of-custody between sample and lot
• Treating one negative result as permanent process proof

What good testing design delivers:

• Defensible release decisions
• Faster incident response
• Better long-term process calibration
