Top 5 Non-Conformities in Food Safety Audits – And How to Prevent Them

 

🧭 Introduction

Food safety audits are a critical part of maintaining trust, compliance, and product integrity in any food manufacturing environment. Whether you're working toward ISO 22000, FSSC 22000, or BRCGS certification, audits reveal how well your food safety management system (FSMS) is being implemented.

As a food safety consultant, I’ve seen recurring non-conformities across facilities of all sizes — from local bakeries to export-certified gelatin and dairy plants. Addressing these issues proactively can prevent certification delays, product recalls, or even plant shutdowns.

In this blog, we’ll explore the top 5 most common non-conformities, real-life examples from the field, and how to fix them before the auditor arrives.

1️⃣ Incomplete or Outdated Documentation

❗ What Auditors Find:

• Missing SOPs or work instructions

• Outdated revision versions in use

• No records of document review or approval

• No version control in place

🔍 Real Example:

A Karachi-based frozen meat exporter had multiple versions of its CCP monitoring form in circulation. Some forms had old temperature limits, causing confusion among staff. During an FSSC 22000 audit, this was raised as a major non-conformity.

✅ How to Prevent:

• Establish clear document control procedures

• Ensure all staff use the latest version

• Schedule quarterly document reviews

• Use software or a spreadsheet for revision control tracking

📌 Tip:

Label all documents with:

• Document number

• Version

• Date of issue

• Approval authority

2️⃣ Poor GMP and Housekeeping Practices

❗ What Auditors Find:

• Dirty equipment or residues near food contact areas

• Peeling paint, cracked floors, stagnant water

• Inadequate pest control documentation

• Open or improperly stored chemicals

🔍 Real Example:

In a sugar syrup plant in Multan, cobwebs were found above the syrup tanks. The plant had no proof of pest monitoring for over 3 months. The auditor raised a minor non-conformity under hygiene and sanitation practices.

✅ How to Prevent:

• Implement a daily GMP checklist signed by supervisors

• Conduct monthly GMP audits using internal teams

• Train all staff on cleaning schedules and protocols

• Maintain a robust pest control contract with proper records

📌 Tip:

Place visual GMP posters in production zones to reinforce hygiene culture.

3️⃣ Inadequate Traceability and Recall System

❗ What Auditors Find:

• No evidence of traceability testing

• Incomplete product and raw material tracking

• No defined recall procedures or mock recall records

🔍 Real Example:

A Lahore-based biscuit manufacturer failed to trace a raw material (milk powder) back to its supplier during an ISO 22000 audit. When the auditor asked for a mock recall test, there was no documentation or recall team assigned.

This was marked as a major non-conformity, delaying certification by 2 months.

✅ How to Prevent:

• Define lot codes and batch tracking for raw materials and finished goods

• Create a recall procedure with a responsible team and contact list

• Perform annual mock recalls and retain records

• Verify your traceability system works forward and backward (from supplier to customer)

📌 Tip:

Use Excel or ERP systems to link materials to final products for traceability.

4️⃣ Inconsistent CCP Monitoring or Records

❗ What Auditors Find:

• Missing or unsigned CCP records

• Monitoring equipment not calibrated

• Staff unaware of CCP limits or corrective actions

🔍 Real Example:

In a gelatin manufacturing plant in Sialkot, CCP temperature monitoring records were filled in bulk at the end of the shift — not in real time. The thermometer used had not been calibrated for 18 months.

The auditor cited this as a critical gap in CCP control under FSSC 22000.

✅ How to Prevent:

• Train CCP operators on real-time monitoring

• Ensure all equipment (e.g., thermometers, pH meters) is calibrated and labeled

• Keep signed records for each monitoring activity

• Display CCP limits and corrective actions clearly at the workstations

📌 Tip:

Use a colored logbook or digital tablet for CCP recording to avoid mix-ups.

5️⃣ Lack of Internal Audits or Management Review

❗ What Auditors Find:

• No internal audit plan or recent audit reports

• No evidence of CAPA follow-up

• Management review meetings not conducted or documented

🔍 Real Example:

A food packaging supplier in Faisalabad had implemented ISO 22000 but hadn’t conducted any internal audits in the last 9 months. Their management review minutes were 2 years old. The certifying body issued a non-conformity for lack of system oversight.

✅ How to Prevent:

• Create an annual internal audit schedule covering all FSMS clauses

• Train internal auditors using ISO 19011 guidelines

• Conduct at least one management review per year

• Maintain proper CAPA records linked to audit findings

📌 Tip:

Use a management review checklist to cover all points: policy, objectives, risks, non-conformities, audit results, and improvements.

🧠 Bonus: Other Common Non-Conformities

• No food safety culture promotion

• Poor allergen segregation and labeling

• Lack of foreign body control (sieves, magnets, metal detectors)

• No environmental monitoring (for high-risk zones)

• Incomplete supplier approval or evaluation records

💼 Consultant’s Advice

“Don’t treat audits as a threat — they are your best tool for improvement. The most successful companies I’ve worked with use audits as a way to grow their teams and refine their processes.”

Start with monthly self-inspections, rotate audit teams, and treat minor non-conformities like early warnings.

📌 Conclusion

Non-conformities are not failures — they are opportunities for continuous improvement. By focusing on these top 5 areas, your food business will be better prepared for:

• Certification audits (ISO 22000, FSSC 22000, BRCGS)

• Regulatory inspections

• Customer audits

And most importantly, you’ll build a safer, more reliable product for your consumers.
