A veterinary clinic runs an autoclave for the same reason a dental office does, but the questions around it are different. Vet teams ask how often to monitor with a biological indicator, what a reprocessing log should hold, which cycle type fits mixed instrument loads, and how to keep instruments moving between patients. This question and answer guide collects eight of the questions Canadian vet clinics send to our compliance desk.
How often should a veterinary autoclave be monitored with a biological indicator?
Daily monitoring is the practical baseline for a veterinary clinic that reprocesses instruments on working days, and it aligns with the direction taken in Canadian health care settings. Ontario dental clinics follow a specific expectation, where the RCDSO expects a biological indicator every day the sterilizer is used, which is daily rather than weekly. The weekly rhythm is the CDC / AAMI ST79 baseline in most US states, and a vet clinic should treat it as a foreign benchmark rather than a local rule. When in doubt, monitor on every day the unit is used.
What should a veterinary reprocessing log contain?
A workable log records the cycle parameters, the load contents, the monitoring result, and the release decision. In a vet clinic the load changes constantly, so a short description such as dental handpieces or a minor surgery pack is more useful than a single tick mark. Keep the log with the sterilizer and add the daily indicator result as a separate line rather than folding it into the cycle data. That separation lets a reviewer see the monitoring cadence at a glance.
Which autoclave cycle types do veterinary clinics use?
Most small-animal clinics run a gravity cycle or a Class B vacuum cycle, and the choice depends on what is being sterilised. A Class B cycle handles wrapped and hollow loads more predictably, while a gravity cycle suits simple solid loads. Whichever cycle is used, the loading pattern and the packaging have to match the cycle so the sterilant reaches the whole load. Overloading a chamber is the most common cause of a wet or failed load in a small practice.
How do you keep instruments organised between patients?
Move to a small number of standardised packs and a colour or label system, so a technician can grab the right set without opening three drawers. Keep wrapped packs in a closed, dry area and check the indicator on each pack before use. Batching a morning load reduces the number of cycles and the amount of handling across the day. A simple label with the load date and the cycle number ties each pack back to a record.
| Parameter | Veterinary clinic guidance | Note |
|---|---|---|
| BI frequency | Every working day the sterilizer is used | Weekly is the CDC / AAMI ST79 baseline in most US states |
| Instrument reference | CSA Z314 | Canadian reprocessing reference |
| Packaging | Sealed pouch or roll per ISO 11607 | Seal and label check at each use |
| Chemical indicators | Every pack, per ISO 11140 classes | Class 5 integrators for wrapped loads |
How should a vet clinic store sterile and used instruments?
Separate the used side from the clean side with a clear physical line, so an instrument never travels backward through the room. Keep wrapped packs in a closed cabinet away from sinks and high-traffic paths, and store used items in a lidded tray until they reach the cleaning step. A one-way workflow removes most cross-contamination questions before an inspector asks them.
Use the printable sterilization log to standardise the record and the sterilization self-check to review the routine. Ask a sterilization compliance specialist if a log needs rebuilding, order case quantities through wholesale, or start daily monitoring with the BI 5-pack trial (CA $12.99, shipping included). Reselling? become a distributor.

Round Out Your Sterilization Setup
A biological indicator is one link in the chain — these are the pieces it works with:
- Sterilization pouches — Class 4 dual-indicator, 200-pack — the packaging the indicator rides inside
- Autoclave indicator tape — 3-roll set — the external chemical indicator on every pack
- Class 5 chemical integrators — 100-pack — the in-pack check that pairs with your biological indicator
- Sterilization roll — 50 m pre-cut sheets for larger instruments
- Constant-heat pouch sealer — 200 °C, 12 mm seal — for consistent pouch closures
Which format does your sterilizer actually need?
Match the readout time to how fast you need the result: a 24-hour self-contained indicator works in any gravity or pre-vacuum cycle with a standard incubator, while a 3-hour fluorescence tube needs the matching reader. Running one cycle type per day, the 25-pack covers a month; busier clinics move to the 100-pack and cut the per-test cost.
How much do spore tests cost in Canada?
Published pricing runs $3.40 per test on the 25-pack down to $2.99 on the 100-pack — no distributor quote, no account needed.

Frequently Asked Questions
Does a veterinary clinic need daily biological monitoring?
Daily monitoring is the practical baseline for a clinic that reprocesses instruments on working days, and it is the safest routine when provincial guidance is unclear.
Is weekly spore testing enough for a veterinary autoclave?
Weekly testing is the CDC / AAMI ST79 baseline in most US states rather than a Canadian rule, so a vet clinic should not treat it as sufficient.
What does a Class B cycle do that a gravity cycle does not?
A Class B vacuum cycle handles wrapped and hollow loads more predictably, while a gravity cycle suits simple solid loads.
How long should reprocessing records be kept?
Keep reprocessing records for the period your provincial regulator expects, and keep each entry traceable to the cycle and the load.
