Turning ISO 22000 Audit Findings Into Real Improvement

Any time I help a company through ISO 22000 or FSSC 22000 certification, one thing always becomes clear: corrective actions tell auditors more about your food-safety culture than any policy or manual ever could. When a finding appears—big or small—it’s your chance to show how your organization learns, adapts, and strengthens its controls.

Most people come to this topic wanting clarity.
“How do we respond to this finding?”
“What does a strong corrective action look like?”
“Are we allowed to just fix the issue and move on?”

This guide gives you a full walk-through of the corrective-action process, from understanding the types of audit findings to performing root-cause analysis and documenting actions correctly. I’ll also share examples of strong (and weak) corrective actions based on what I’ve seen across different sectors—from ready-to-eat processors to distributors and packaging companies.

Now that we’ve set the stage, let’s look at how audit findings actually work.

Understanding Audit Findings: Majors, Minors & Observations Explained

Before you can respond properly, you need to understand what each type of finding means.

Major Nonconformities:
These represent a breakdown in your FSMS or a serious food-safety risk—such as a CCP monitoring failure or traceability breakdown. They usually stop certification until corrected.

Minor Nonconformities:
These indicate partial implementation or isolated issues—for example, missing signatures, outdated procedures, or some weak PRP practices.

Observations:
These aren’t NCs but early warning signs. Auditors use them to highlight potential future problems.

I’ve seen companies relax when they get an “observation,” but in my experience, observations become next year’s nonconformities if ignored.

Pro Tip: Treat observations as small fires and put them out before they spread.

Common Pitfall: Only focusing on major NCs while minor ones continue repeating year after year—this signals ineffective corrective action and triggers deeper scrutiny.

The Corrective-Action Process: From Investigation to Verification

Corrective actions aren’t just about fixing what went wrong. They’re about preventing the issue from happening again. ISO expects a structured, logical process that shows a clear line from finding → root cause → action → verification.

A strong corrective-action process includes:

1. Document the NC
   Capture the finding clearly, including where it occurred and why it matters.
2. Containment Actions (Immediate Fix)
   Stop the problem from continuing.
   Example: If a CCP log is missing entries, retrain the operator immediately and start monitoring correctly.
3. Root-Cause Analysis
   Understand why the issue happened.
4. Corrective-Action Plan
   Define actions that prevent recurrence.
   These must be realistic, measurable, and time-bound.
5. Implementation
   Train staff, update procedures, revise forms, or redesign workflows as needed.
6. Verification of Effectiveness
   This step is essential. Auditors want proof the issue truly stopped happening.
7. Closure & Documentation
   Keep all evidence organized—certification auditors will review it.

Pro Tip: Separate containment from corrective action. Quick fixes show responsiveness; corrective actions show maturity.

Common Pitfall: Closing NCs within a week—without enough time to verify results.

Root-Cause Analysis Tools for ISO 22000 (5 Whys, Fishbone, Error Analysis)

Root-cause analysis (RCA) is where companies often struggle. It’s tempting to write “human error” or “staff forgot,” but auditors will push back on that immediately.

Some practical RCA tools include:

5 Whys

A simple, fast tool to drill into deeper causes.

Fishbone (Ishikawa) Diagram

Helps you analyze causes across categories—people, methods, materials, machines, environment.

Error-Type Analysis

Useful when dealing with procedural, training, or system errors.

Weak RCA example:
“Operator forgot to record CCP temperature.”

Strong RCA example:
“Temperature monitoring form was confusing, training was outdated, and supervision checks were inconsistent.”

I’ve seen operators blamed unfairly when the real issue was unclear procedures or lack of practical training.

Pro Tip: Involve the people who do the work. They often reveal operational realities managers overlook.

Common Pitfall: Stopping the RCA after one layer of analysis.

Building Effective Corrective Actions (With Examples You Can Use)

A corrective action should feel like a solution that will stand the test of time—not a band-aid.

Effective corrective actions are:

• Specific
• Systemic
• Measureable
• Time-bound

Here are a few examples based on typical findings:

PRP Failure Example

Finding: Cleaning logs incomplete.
Weak Action: “Remind staff to fill out the log.”
Strong Action:

• Redesign cleaning form
• Provide hands-on training
• Implement weekly supervisory checks
• Review log completeness during internal audits

CCP Monitoring Failure Example

Finding: Missing CCP temperature checks.
Strong Action:

• Retrain operators with practical demos
• Simplify the monitoring form
• Add alarms or visual reminders
• Verify logs daily for one month

Document-Control Issue Example

Finding: Multiple versions of a procedure in circulation.
Strong Action:

• Implement centralized document control
• Train staff on version use
• Remove and archive old copies
• Review procedure distribution quarterly

Pro Tip: Connect corrective actions to FSMS objectives—it shows direction and intent.

Common Pitfall: Fixing the symptom (“fill the form correctly”) instead of fixing the system.

Preventing Recurrence: Verification, Monitoring & Continual Improvement

Preventing recurrence is the part most companies ruh, but it’s the step auditors pay the closest attention to.

Verification may involve:

• Reviewing records for several weeks
• Observing actual practices
• Interviewing staff
• Checking trend data
• Re-running internal audits

One company I worked with improved their allergen-control system simply by adding a monthly trend review. What used to be repeated issues disappeared in under a quarter.

Pro Tip: Add major corrective actions to the management-review agenda—leadership oversight strengthens the FSMS.

Common Pitfall: Closing NCs based on updated paperwork, not actual implementation.

Corrective-Action Documentation & Evidence Needed for Certification Bodies

Auditors want to see a clean, logical flow of evidence. Disorganized documentation makes the closure look incomplete—even if the actions were strong.

A complete record should include:

• Description of NC
• Evidence of immediate containment
• Root-cause analysis worksheet
• Corrective-action plan with deadlines
• Updated documents or training records
• Photos, logs, or checklists showing implementation
• Verification evidence
• Closure approval

I once saw a company lose two hours of audit time because they kept corrective-action evidence in five different folders. When documentation is scattered, it weakens the story of your FSMS.

Pro Tip: Use one standardized corrective-action form or digital log.

Common Pitfall: Forgetting to attach updated procedures or training attendance sheets.

Templates, Forms & Tools You Should Use (Download Section)

Your downloadable corrective-action toolkit should include:

• Corrective-Action Form (CA/NC Form)
• 5 Whys RCA Worksheet
• Fishbone Diagram Template
• Effectiveness Verification Checklist
• NC Tracker or Log

Together, these tools help you structure the entire process—from identifying the issue to confirming the fix worked.

Short instructions for use:

• Start with the NC form to document the issue
• Use 5 Whys or fishbone for root cause
• Complete the corrective-action plan section
• Attach evidence as implementation progresses
• Perform effectiveness checks after 2–8 weeks
• Close only when recurrence risk is eliminated

FAQs

How fast do we need to close corrective actions?

Most certification bodies expect closure within 30–90 days, depending on severity.

Can we challenge a nonconformity?

Yes—if you have objective evidence. Otherwise, accept it and build a stronger system.

How detailed should RCA be?

Detailed enough to show you truly addressed the root cause—not just the surface symptom.

Conclusion: Build a Stronger FSMS by Closing Audit Findings the Right Way

Corrective actions are one of your strongest tools for strengthening your food-safety system. When you investigate issues properly, involve your team, and verify improvements over time, you’re not just closing findings—you’re building a culture that prevents future issues.
