Essential Guide to the IFS Audit: Key Insights and Best Practices

The IFS (International Featured Standards) Food Standard is a globally recognized, GFSI-benchmarked food safety certification scheme that manufacturers and processors use to prove their products and processes meet rigorous safety and quality expectations. Certification lets suppliers assure customers of consistent safety practices, improve food quality, and expand into international markets.

Although IFS standards originated in Europe, they matter increasingly to U.S. businesses as major retailers and foodservice operators require suppliers to follow Global Food Safety Initiative (GFSI)-benchmarked schemes. This guide explains why the standard matters, its key components, how the audit and scoring work, and how to prepare.

Why the IFS Food Standard Matters

Demonstrating adherence to recognized safety standards is essential for securing contracts and maintaining customer trust. The IFS Food Standard focuses on producing, packaging, and handling products in a way that prevents contamination and preserves quality, and certification delivers several benefits.

• Market access and consumer confidence: Many retailers and brand owners require GFSI-recognized certifications, and IFS helps companies qualify for those supply chains while assuring consumers of rigorous standards.
• Streamlined audits: Because IFS Food is internationally recognized, one comprehensive audit reduces the need for multiple customer audits.
• Improved processes: The standard builds a culture of safety and quality that helps identify weaknesses, reduce waste, and improve efficiency.
• Risk management: Required hazard analysis and control measures help businesses proactively prevent food safety incidents.

Key Components of the IFS Food Standard

The standard covers several critical aspects of production and processing that form the foundation of a robust quality management system. Understanding these components is the starting point for building a compliant program.

Food safety management system

At the core is a documented, risk-based food safety management system aligned with applicable regulations, with policies and procedures to identify, evaluate, and control hazards. Companies must show commitment through leadership engagement, employee training, and sufficient resources, integrating Good Manufacturing Practices, Good Hygiene Practices, and strong cleaning and maintenance programs so facilities, equipment, and people do not contribute to contamination.

Hazard analysis and critical control points (HACCP)

IFS requires a thorough hazard analysis based on Codex Alimentarius principles, identifying biological, chemical, and physical hazards and determining critical control points (CCPs). For each CCP, the company sets critical limits such as time, temperature, or pH, with monitoring procedures to confirm those limits are met and corrective actions defined for any deviation.

Supplier and raw material management

Strong supplier management is essential, so companies must evaluate suppliers to ensure raw materials meet safety and quality specifications. Incoming materials should be inspected and supplier compliance documented, with the system covering contamination risk at different points in the supply chain.

Product development and specifications

IFS emphasizes accurate product specifications that reflect customer requirements and regulations, covering ingredients, allergens, packaging, shelf life, and storage. Companies must validate manufacturing processes so the finished product consistently meets those specifications, with label and artwork controls keeping product information accurate and compliant.

Traceability and recall procedures

Traceability systems are mandatory, so businesses must be able to trace ingredients and products throughout the food chain and recall products quickly when a risk is identified. Regular recall simulations test the system's effectiveness, and maintained documentation demonstrates compliance during an audit.

IFS Audit Process and Scoring System

Certification is achieved through audits by accredited certification bodies, conducted by qualified auditors who assess the food safety management system, processes, hygiene, documentation, and legal compliance.

Audit types and frequency

Audits can be announced or unannounced, and unannounced audits show a company maintains continuous compliance rather than preparing only for scheduled inspections. A successful audit results in certification valid for one year, and the frequency of follow-up audits depends on the severity and number of non-conformities, with major or critical findings sometimes requiring a complete re-audit.

Scoring categories

The IFS system rates each requirement as A (full compliance), B (minor deviation not compromising safety or quality but needing improvement), C (deviation with impact on safety or quality requiring corrective action), or D (severe deviation compromising safety or significantly failing requirements). Certain requirements are defined as KO (Knock Out), and failing one results in an overall failed audit regardless of other scores.

KO criteria

The standard includes a set of Knock Out requirements, critical areas where failure causes automatic audit failure regardless of the overall score. These include senior management commitment, CCP monitoring, traceability, hygiene, and recall readiness, each a non-negotiable pillar of the food safety system.

Calculating the overall score

Each requirement is scored, and points are assigned by rating, then totaled as a percentage of the maximum possible points, excluding non-applicable requirements. The resulting percentage determines the grade, where higher percentages reflect higher performance, and companies with high scores may qualify for IFS Star status if they also undergo an unannounced audit.

Preparing for an IFS Audit

Implementing the standard takes careful preparation, and a systematic approach ensures every requirement is addressed and employees understand their roles. Work through these seven steps.

Understand the standard

Obtain the latest version of the IFS Food Standard and review it thoroughly, focusing on the structure, scope, and specific requirements, then identify where current practices align and where gaps exist.

Conduct a gap analysis

Compare your current food safety management system against the IFS requirements to highlight where improvements are needed, documenting each gap and creating an action plan, with internal or consultant support as needed.

Update policies and procedures

Based on the gap analysis, develop or revise policies and procedures covering hazard analysis, critical control points, supplier management, cleaning, and recordkeeping, ensuring documentation reflects actual practice and staff can demonstrate compliance.

Train employees

Train staff on hazard analysis, CCPs, hygiene, cleaning, and recordkeeping, emphasizing personal hygiene and each person's role in food safety, with regular refreshers to sustain competence.

Perform internal audits

Run internal audits to evaluate whether the system is effective and meets IFS requirements, catching non-conformities before the official audit, using auditors who understand the standard and are impartial to the area being reviewed.

Implement corrective actions

When internal audits find non-conformities, create corrective action plans that assign responsibility, set deadlines, and track progress to resolution, demonstrating continuous improvement.

Choose a certification body and schedule an audit

Select an accredited body experienced in your sector using the IFS database, decide between an announced or unannounced audit, and schedule it during typical operations that represent normal production.

Summary of IFS Scoring Categories and Impact

The rating a requirement receives shapes both the overall score and the certification outcome.

Implementing the IFS Food Standard in a Restaurant Environment

The IFS Food Standard is usually associated with industrial manufacturers, but many of its principles apply to restaurants and foodservice, where they raise safety and quality, reduce risk, and improve customer satisfaction.

1. Food safety culture: Make food safety a core value, with leadership communicating expectations, providing training and support, and encouraging staff to speak up about hazards.
2. Documented procedures: Write clear procedures for food preparation, cooking, storage, and service that spell out control points like cooking temperatures and cooling times, and have staff follow them consistently.
3. Supplier verification: Audit and approve suppliers for compliance with relevant food safety standards, and request certificates of analysis and traceability information.
4. Personal hygiene: Enforce strict hygiene protocols, including handwashing, protective clothing, and illness reporting, reinforced by regular training.
5. Environmental monitoring: Clean and sanitize equipment and surfaces regularly, implement pest control, and maintain facilities to minimize risk.
6. Recordkeeping: Keep records of temperatures, cleaning schedules, supplier deliveries, and staff training to demonstrate compliance and answer inspector or customer inquiries.

Even without pursuing formal certification, adopting IFS principles positions restaurants to meet supplier requirements, strengthen vendor relationships, and future-proof their food safety systems.
