Context and history
FDA issued this warning letter to Jost Chemical Co. on 18 Jul 2022. It concerns active ingredients, and it is listed here because of what it says about computerised systems or data integrity. FDA warning letters are public, and this one names the firm. It concerns one firm at one point in time, and it says nothing about the firm today or about other firms.
Who and what it applies to
This one firm. It is a record of enforcement, not guidance for everyone.
What it contains
- Quality unit
- Complaints were not properly investigated.
- Cleaning and test methods
- Procedures and methods were not adequate.
- Computerised systems
- Failure to control systems against unauthorised access or changes, and to set procedures for their operation and maintenance.
Key points
- Audit trail review applies to production equipment as well as laboratory equipment.
- FDA looks for a stated frequency.
- It binds one firm, and it shows how FDA applies existing rules.
In practice
General reading, not advice. This is drafted with AI and may not fit your situation. It does not replace the official text, your own quality system or qualified advice, and an inspector may take a different view.
- State who reviews audit trails, for which systems, and how often.
