What an inspector checks in Oregon
When a Oregonboard inspector or surveyor reviews a practice's sterilization records, they're confirming the monitoring actually happened and is documented. Expect them to look for:
- A spore-test log showing at least weekly biological monitoring of every heat sterilizer in use.
- Records retained for at least 3 years and available on site.
- Chemical-indicator results recorded for processed loads, plus mechanical (time/temp/pressure) confirmation.
- Documented corrective action for any failed spore test, including retest and instrument recall.
- Compliance consistent with OAR 818-012-0040 (Oregon Board of Dentistry, Infection Control).

- Follow the CDC protocol: immediately take the affected sterilizer out of service, review the load, and re-test. Re-process and recall any implicated instruments as directed, document every step with dates and initials, and only return the sterilizer to service after a passing biological test. Keep this corrective-action record with your Oregon sterilization log — inspectors look for it.
