Food manufacturers face unique compliance requirements. Here's exactly what maintenance records FDA and USDA auditors look for — and how to keep them audit-ready at all times.
Note: This article provides general guidance. Requirements vary by facility type, product category, and regulatory body. Consult your compliance team or a food safety consultant for facility-specific requirements.
Food manufacturing has always required meticulous record-keeping. But since the FDA's Food Safety Modernization Act (FSMA) expanded preventive controls requirements in 2016, maintenance records have become a central part of food safety compliance — not just an operational nicety.
If you're running a food processing facility — whether you're FDA-regulated, USDA-inspected, or SQF/BRC certified — your maintenance records need to be complete, accurate, and retrievable on demand. Here's what that means in practice.
Under FSMA's Preventive Controls for Human Food rule (21 CFR Part 117), food manufacturers must establish, implement, and monitor preventive controls — including equipment maintenance — as part of their Food Safety Plan. And critically, they must keep records proving they did so.
For USDA-inspected facilities (meat, poultry, egg products), similar requirements exist under HACCP regulations (9 CFR Part 417). Third-party certification schemes like SQF, BRC, FSSC 22000, and AIB also require documented maintenance programs with auditable records.
FDA inspectors don't just ask if you have a maintenance program — they ask to see the records. Common requests include: "Show me the maintenance log for your metal detector for the last 6 months" and "When was your filler last calibrated, and where's the record?" If you can't retrieve it in minutes, it's a finding.
While requirements vary by facility type and certification scheme, most food safety audits will look for records in four categories:
| Record Type | FDA (FSMA) | USDA (HACCP) | SQF/BRC |
|---|---|---|---|
| Preventive control monitoring | 2 years | 1 year | 1 year minimum |
| Calibration records | 2 years | 1 year | 1 year minimum |
| Corrective action records | 2 years | 1 year | 1 year minimum |
| Verification records | 2 years | 1 year | Per scheme requirement |
| Supplier verification | 3 years | N/A | Per scheme requirement |
When in doubt, keep records for at least 2 years from creation date. For facilities under multiple regulatory frameworks, follow the most stringent requirement.
Technicians complete the work but don't log it. This is especially common for quick daily tasks. If it's not recorded, from a compliance standpoint it didn't happen.
Paper binders, local spreadsheets, or email threads mean it takes 30+ minutes to pull records for a specific machine and date range. Auditors notice — and it signals disorganization.
When a PM was skipped or equipment was found in a degraded state, you need a corrective action record explaining what was done and when. Most shops document the repair but not the corrective action reasoning.
Calibration logs often live in a separate binder from maintenance logs. Auditors want to see the complete equipment history in one place — not hunt across multiple systems.
The key to audit readiness is that records need to be complete, timestamped, and searchable. Here's the standard that world-class food manufacturers hold themselves to:
Whether a PM was completed or skipped, there's a record. If skipped: a brief note explaining why and what the corrective action was.
When an auditor asks "show me all maintenance on Line 2 filler from January to June," you can produce it in under 5 minutes.
Technician name (or ID), task performed, date and time completed, and any findings or issues noted.
When something is out of spec or a task was missed, the corrective action — including root cause and resolution — is logged as a separate record linking back to the original finding.
Paper records are vulnerable to loss, damage, and illegibility. Digital records in a centralized system are searchable, backed up, and harder to dispute.
Myncel automatically timestamps every work order, tracks who completed it, and stores your complete maintenance history — making FDA and USDA audit prep straightforward.
