WHAT IS ISO 22000 FROM THE PERSPECTIVE OF A CERTIFICATION AUDITOR?

In the food industry, even a small mistake can lead to product recalls, brand reputation damage, or serious legal risks. Therefore, more and more businesses are paying attention to building a food safety management system in accordance with ISO 22000:2018.

However, many companies still do not fully understand what ISO 22000 is. They often implement it merely for compliance purposes, prepare documentation only as a formality, or apply the standard incorrectly. As a result, the certification process becomes prolonged and generates unnecessary costs.

What is ISO 22000?

ISO 22000 is an international standard for Food Safety Management Systems (FSMS) issued by the International Organization for Standardization.

This standard helps businesses control all food safety hazards throughout the supply chain, including:

• Raw materials

• Production

• Processing

• Packaging

• Storage

• Transportation

• Distribution

Unlike approaches that focus only on testing the final product, ISO 22000 requires businesses to establish a preventive control system, helping reduce food safety risks from the very beginning.

Which Businesses Are Suitable for ISO 22000?

This standard is widely applied to:

• Food manufacturing factories

• Seafood and agricultural processing companies

• Restaurants and industrial kitchens

• Cold storage and food logistics providers

• Food packaging manufacturers

• Export food supply chains

1. Common Problems Businesses Face When Implementing ISO 22000

From the perspective of certification auditors, many businesses encounter difficulties right from the beginning because they do not fully understand the true nature of the standard.

Common issues include:

- Lack of Understanding of the true nature of ISO 22000

Many businesses believe that ISO 22000 is simply:

• A set of documents required to obtain certification

• A tool for bidding purposes

• A condition for export activities

In reality, ISO 22000 is a management system integrated throughout the entire business operation.

- Failure to properly identify food safety hazards

Businesses often:

• Conduct superficial hazard analysis

• Copy documents from other companies

• Fail to assess hazards based on actual production conditions

As a result, the system loses its effectiveness in controlling risks.

• Excessive documentation but unrealistic operations

This is a very common issue:

• Procedures are written in great detail
• Documentation looks well-prepared
• But employees do not actually follow the procedures

During on-site audits, certification experts can easily identify these inconsistencies.

• Lack of commitment from top management

Many companies assign the entire implementation process to the QA/QC department without active involvement from top management.

This leads to:

• Difficulty maintaining the system
• Insufficient resources
• Poor coordination between departments

2. Certification Auditors’ Perspective: The True Nature of ISO 22000

ISO 22000 Certification – A safety management solution for businesses

ISO 22000 is not simply about “paperwork.” The core issue is:

Can the business truly control food safety risks?

• Certification auditors usually focus on:
• Consistency between documentation and actual operations
• Traceability capability
• CCP/OPRP control
• Incident handling capability
• Employee awareness and understanding

ISO 22000 combines HACCP and system management

ISO 22000 integrates:

• HACCP principles
• Risk-based thinking
• The PDCA cycle
• Continuous improvement

Therefore, businesses should not only aim to “pass the audit” but also build a sustainable operational management system.

• Real audits are completely different from formalistic audits

During certification assessments, auditors may:

• Directly inspect production sites
• Interview any employee randomly
• Review records randomly
• Trace finished products back to raw materials

If the system is not genuinely implemented, obtaining certification becomes very difficult.

3. Common Practical Mistakes Businesses Often Make

- Incorrect CCP establishment

Many businesses:

• Identify too many CCPs
• Or identify CCPs incorrectly

Consequences include:

• Complex documentation
• Difficult monitoring
• Increased risk of nonconformities
• Failure to distinguish between PRP – OPRP – CCP

This is one of the most common mistakes in ISO 22000 implementation. Incorrect classification can result in:

• Loss of system logic
• Ineffective control measures
• Major nonconformities easily detected during audits
• Incomplete traceability records

Common issues include:

• Missing batch codes
• No linkage between raw materials and finished products
• Inaccurate production time records
• Formalistic employee training

Many employees:

• Do not understand what a CCP is
• Do not know how to handle deviations
• Only sign training attendance forms
• Poor supplier control

ISO 22000 requires businesses to:

• Evaluate suppliers
• Conduct periodic monitoring
• Control incoming material quality

However, many companies overlook this requirement.

4. Step-by-Step Guide to Proper ISO 22000 Implementation

Step 1: Assess the current situation of the business

The assessment should include:

• Production processes
• Factory infrastructure
• Existing documentation
• Legal compliance status

This step identifies the gap between current practices and ISO 22000 requirements.

Step 2: Establish a food safety team

The FSMS team should include:

• Top management representatives
• QA/QC personnel
• Production department
• Warehouse and logistics staff
• Purchasing department

Step 3: Conduct hazard analysis according to HACCP

Businesses need to:

• Identify biological hazards
• Identify chemical hazards
• Identify physical hazards
• Assess risk levels
• Determine control measures

Step 4: Establish PRP – OPRP – CCP

This includes:

• GMP
• SSOP
• Temperature control
• Foreign object control
• Food allergen control
• Equipment sanitation

Step 5: Develop the documentation system

Documents should:

• Reflect actual operations
• Be easy to apply
• Be easy to train employees on
• Avoid unnecessary complexity

Step 6: Training and trial operation

Businesses should provide:

• ISO 22000 awareness training
• CCP/OPRP training
• Incident handling training

Afterward, the system should be operated for at least 2–3 months before certification assessment.

Step 7: Internal audit and corrective actions

Objectives:

• Identify nonconformities
• Correct deviations
• Improve the system before the certification audit

Step 8: Certification audit

The process includes:

1. Stage 1 audit
2. Stage 2 audit
3. Corrective actions for nonconformities
4. ISO 22000 certification issuance

6. Operational and Legal Benefits of Implementing ISO 22000

• Enhancing customer trust and brand reputation

ISO 22000 helps businesses:

• Improve brand credibility
• Gain easier access to supermarket supply chains
• Increase export opportunities
• Reducing food safety risks

The system helps businesses:

• Prevent operational errors
• Reduce the risk of product recalls
• Respond to incidents more quickly and effectively
• Optimizing internal operations

When properly implemented:

• Processes become clearer and more standardized
• Responsibilities become more transparent
• Data becomes easier to monitor and control
• Meeting legal and customer requirements

ISO 22000 supports businesses in complying with:

• Food safety regulations
• International customer requirements
• Tendering and export conditions

Understanding “what is ISO 22000” truly is not only helps businesses achieve certification faster, but also enables them to build a safe, sustainable operational system while reducing long-term legal risks.

From the perspective of certification auditors, the key factor for success is not the quantity of documents, but the company’s ability to operate the system effectively, practically, and consistently.

If implemented correctly from the beginning, businesses can:

• Save time
• Reduce corrective action costs
• Increase certification success rates
• Enhance competitiveness in the market
