Preparing Your Food Manufacturing Facility for an SQF Audit
Sanitation is where SQF audits are won or lost. This guide walks food manufacturers through the six areas auditors scrutiniz
Few dates on a food manufacturer'scalendar carry more weight than an SQF audit. Certification keeps retailcontracts alive, opens doors with new buyers, and signals to the entire supplychain that your facility takes food safety seriously. And while SQF coverseverything from document control to supplier approval, ask anyone who has satthrough an audit and they will tell you the same thing: sanitation is whereaudits are won or lost.
Auditors can forgive a typo in apolicy document. They cannot forgive a drain with biofilm, an unlabeled spraybottle, or a Master Sanitation Schedule that stopped being followed in March.Sanitation findings are visible, verifiable, and hard to argue with, which isexactly why they show up so often in nonconformance reports.
This guide walks through the sixareas of your sanitation program that deserve the closest attention beforeaudit day, based on what our teams see inside food manufacturing facilitiesacross the Twin Cities. At the end, you can download the full checklist to walkyour own facility, line by line.
Why Sanitation Carries So MuchWeight in an SQF Audit
The SQF Food Safety Code dedicatesentire modules to the cleanliness of premises, equipment, and personnelpractices, and auditors verify those requirements in the most direct waypossible: they look. They open equipment, they run fingers along ledges, theylift drain covers, and they pull your records to see whether what youdocumented matches what they observe.
That last point matters more thanmost facilities realize. A gap between your paperwork and your plant is worsethan a weak spot in either one alone, because it tells the auditor yourverification program is not catching problems. The goal of audit preparation isnot to make the facility look good for one day. It is to prove that yoursanitation system works every day, and that you would catch it if it did not.
Start 30 to 60 Days Before YourAudit Window
A facility cannot deep-clean itsway out of a systemic gap in a single weekend. Records need time to accumulate,corrective actions need time to close, and re-swabs need time to come backclean. Walking your facility with a checklist 30 to 60 days out gives youenough runway to fix what you find and to document that you fixed it, which isprecisely the evidence an auditor wants to see.
Here is where to focus thatwalkthrough.
1. Documentation and Records
Your Master Sanitation Schedule isthe first document most auditors request, and it needs to answer threequestions cleanly: is every area and piece of equipment on it, is every taskassigned a frequency and an owner, and is every completed task signed off?Overdue tasks with no explanation are among the easiest findings an auditorwill ever write.
From there, confirm that yourSanitation Standard Operating Procedures describe how cleaning actually happenstoday, not how it happened when the SSOP was written. Equipment changes,chemical changes, and staffing changes all have a way of drifting ahead of thepaperwork. Finally, check that training records are current for every personwho touches sanitation, including temporary labor. Auditors know that turnoveris high in sanitation roles, and they check whether your training program keepsup.
2. Chemical Control
Walk into your chemical storagearea with your approved chemical list in hand. Anything on the shelf that isnot on the list is a finding waiting to happen, and so is anything on the listyou can no longer locate a Safety Data Sheet for.
Then look at the day-to-daydetails. Concentration verification, whether by titration or test strips,should be logged at the frequency your program specifies. Secondary containersand spray bottles must be labeled, every single one. And chemicals need to bestored away from ingredients, packaging, and food-contact surfaces. These aresmall items individually, but auditors read them as indicators of howdisciplined the whole program is.
3. Equipment and Food-ContactSurfaces
Food-contact surfaces get the mostscrutiny of anything in the facility, and rightly so. Confirm that equipment isbeing disassembled to the level your SSOPs specify, because partial breakdownsleave harborage points that swabs eventually find. Inspect surfaces forpitting, cracks, and corrosion, all of which are places cleaning chemistrycannot fully reach.
Your verification data should backup what your eyes see. ATP or microbial swab results taken after cleaningshould be trending within your limits, and out-of-spec results should show adocumented re-clean and re-test. Do not overlook the tools themselves: frayedbrushes, worn scrapers, and color-coded tools that have wandered between zonesall signal cross-contamination risk to an auditor.
4. Facility and Environment
Drains deserve their own line itemin any audit preparation plan. They are a known harborage point for Listeria,auditors always check them, and they must be cleaned with dedicated tools thatnever touch anything else. If your drains are not on the Master SanitationSchedule with their own frequency, fix that first.
Then look up. Overhead pipes,beams, and light fixtures collect dust and condensation that can fall directlyinto product zones. Look around: walls, floors, and ceilings need to becleanable and in good repair. And look at movement, because traffic patternsthat let people or equipment flow from raw areas to ready-to-eat areas withoutcontrols are a zoning finding that no amount of scrubbing will offset.
5. Allergen and Cross-ContactControls
If your facility runs allergens,your changeover cleaning program will get specific attention. Every changeoverscenario you run should have a documented procedure, and your validationrecords need to prove those procedures actually remove the allergen, backed bycurrent verification swabs.
Auditors also look at thepractical side: whether tools used between allergen runs are dedicated orproperly sanitized, and whether your production scheduling minimizeschangeovers in the first place. A scheduling matrix that runsallergen-containing products last is one of the cheapest risk reductionsavailable to any food manufacturer.
6. Pre-Operational Verification
Pre-op inspection is where yoursanitation program proves itself every single morning. Confirm that adocumented pre-op is completed and signed before every production start, andthat failures trigger a re-clean and re-inspection before the line is released.An auditor who finds a pre-op failure with no follow-up has found somethingmuch bigger than a dirty conveyor.
Close the loop on yourenvironmental monitoring program as well. Results should be reviewed, trendsshould be documented, and every corrective action from prior audits andinspections should be closed with evidence. Open corrective actions from yourlast audit are the single most predictable finding in any re-certification.
The Findings We See Most Often
Across the facilities our crewsand consultants work in, the same handful of issues account for most sanitationnonconformances:
• MasterSanitation Schedules with overdue tasks and no documented justification
• Unlabeledsecondary chemical containers, usually spray bottles
• Drainsmissing from the schedule or cleaned with shared tools
• SSOPsthat no longer match current equipment or chemicals
• Verificationswab failures without a documented re-clean and re-test
None of these are expensive tofix. All of them are expensive to have written up.
