Ontario Meat Plant Pre-Operational Inspections: Records and Corrective Action
Last reviewed: 2026-08-17 · Primary sources verified in InspectionDay regulatory datasets
Before production begins on each operating day, Ontario provincial meat plants are expected to verify that premises, equipment, and utensils meet the plant's sanitation program. This daily operator verification is separate from a ministry field inspection before licensing or after major alterations.
What is a pre-operational inspection in an Ontario meat plant?
Under O. Reg. 31/05 s. 47(6) and MPG Part 6, the operator must ensure that on each day the plant operates, a pre-operational inspection of premises, equipment, and utensils is conducted before operations begin to confirm compliance with the sanitation program.
When should pre-op happen?
On every operating day, before production starts on affected areas or lines. If the plant does not operate that day, a pre-op record for that day is generally not required — but multi-shift plants should define in the written program what counts as an operating day and whether each shift requires its own verification.
What needs to be checked
MPG guidance expects inspections to cover areas relevant to the sanitation program — not a random subset. That commonly includes production and support areas, equipment condition and function, sanitizer concentration where monitored, hand-washing facilities, housekeeping, pest-control observations where applicable, and refrigeration/freezing temperatures required under O. Reg. 31/05 s. 30 and recorded during pre-op under s. 47(6.1).
Cleaning vs verification
Sanitation staff perform cleaning and sanitizing according to the written program. Pre-op is the verification step that confirms those activities were effective before product contact resumes. The pre-op record documents that verification — it is not a substitute for sanitation monitoring records made on the day sanitation work occurs (O. Reg. 31/05 s. 47(5)).
If something is not acceptable
Production should not proceed on affected lines or areas until the condition is corrected and verified. Document the unacceptable condition, what was observed, and what was done before operations resume.
Can production start if pre-op finds a problem?
Ontario expects unacceptable conditions to be corrected before operations proceed on affected areas. Do not start production on lines or equipment that failed verification until the condition is fixed and re-checked.
Immediate correction vs corrective action
An immediate correction addresses the specific finding before production resumes — for example re-cleaning a surface, adjusting sanitizer concentration, or holding a cooler line until temperature stabilizes. A corrective action is deeper follow-up when the finding suggests a systemic gap in the sanitation program, repeated failure, or a root cause that immediate correction alone cannot address.
- Immediate correction: documented on or with the pre-op record; production waits on affected areas until verified.
- Corrective action: assigned responsibility, due date, and separate verification when the sanitation program or quality system requires it.
- Not every deviation requires both — but every significant deviation should be documented so later reviewers can see what happened.
What follow-up looks like
- Record the original pre-op finding on the operating day.
- Document immediate correction and re-verification before production resumes.
- Open a corrective action when the program requires root-cause follow-up.
- Verify the corrective action separately when assigned.
- Keep linked history so an inspector can move from the pre-op deviation to correction and any corrective action without searching multiple binders.
What belongs in the record
Illustrative pre-op record (not a prescribed form)
MPG requires written records at the time of inspection. A practical record often includes:
- Operating date (and shift if the program distinguishes shifts)
- Area, line, or equipment item checked
- Condition observed (acceptable / requires attention)
- Measured values where required (e.g., sanitizer concentration, cooler temperature)
- Person performing or signing off the inspection
- Immediate correction notes when something is not acceptable
- Re-verification note before production resumed
- Corrective action reference if deeper follow-up was opened
These fields illustrate useful information — they are not a statutory checklist of mandatory column headings. Field labels should follow the plant's written program and applicable MPG elements.
Example scenario
A cooler temperature reading during pre-op is above the plant's written limit:
- Pre-op record: cooler #2 recorded at 5 °C; marked requires attention.
- Immediate correction: product moved, unit serviced, line held.
- Re-verification: second reading recorded at 2 °C; line released.
- Corrective action (if required by program): assign investigation of repeated cooler drift with due date and verification.
InspectionDay records this as linked history. Whether the response satisfies Ontario requirements is determined by the plant's programs and the applicable authority.
What an inspector may ask for later
Pre-op records for the requested period, linked sanitation monitoring for the same operating days, temperature records captured during pre-op, evidence that unacceptable items were corrected before production continued, and any corrective actions opened from pre-op deviations with verification completed.
Common questions
- What should be on a pre-op inspection?
- Items relevant to your sanitation program — areas, equipment, sanitizer checks where monitored, hand-washing and housekeeping conditions, and refrigeration/freezing temperatures where O. Reg. 31/05 requires them during pre-op.
- What is the difference between immediate correction and corrective action?
- Immediate correction fixes the specific finding before production resumes on affected areas. Corrective action is follow-up assigned when the program requires root-cause analysis or systemic correction beyond the immediate fix.
- Can production start if pre-op finds a problem?
- Ontario expects unacceptable conditions to be corrected and verified before operations proceed on affected areas. Document what was found and what was done before production resumes.
- How long must Ontario pre-op records be kept?
- Retention depends on the specific requirement. For example, refrigeration/freezing temperature records during pre-op must be kept at the plant at least until the anniversary of the date they were made (O. Reg. 31/05 s. 47(6.2)). Other sanitation records have their own retention expectations in MPG Part 6.
