What is a Food Safety Compliance Audit & How to Conduct It?

In a recent incident, Frito-Lay recalled certain 13-ounce bags of Tostitos Cantina Traditional Yellow Corn Tortilla Chips because some of the packages were mistakenly filled with nacho cheese tortilla chips, which contain an undeclared milk allergen. 

Distributed across several U.S. states, this recall shows a critical truth in the food industry: even minor packaging errors can pose serious health risks to consumers with allergies.

A single oversight, like mixing up chip varieties, led to a brand-wide recall, negative publicity, and potential customer harm. 

One of the most effective ways to prevent similar scenarios is to conduct regular food safety compliance audits. 

In the guide below, we’ll explain what these audits involve, why they’re vital, and how to implement them effectively from start to finish.

What Is a Food Safety Compliance Audit?

A food safety compliance audit is a systematic, in-depth evaluation of a food business’s adherence to established food safety standards and regulations. 

These standards may include federal, state/provincial, or local regulations, such as the FDA’s Food Safety Modernization Act (FSMA) in the United States or internationally recognized frameworks like Hazard Analysis and Critical Control Points (HACCP), ISO 22000, the British Retail Consortium (BRC), or Safe Quality Food (SQF).

Food safety compliance audits typically involve:

1. Reviewing Documentation: Verifying that all required policies, procedures, and records (e.g., HACCP plans, training logs, cleaning schedules) are current and accurate.

2. Inspecting Facilities and Equipment: Ensuring that the physical environment (e.g., production lines, storage, and refrigeration) meets sanitary design and operational standards.
3. Observing Operational Practices: Watching employees in their daily tasks to confirm they follow proper hygiene, handling, and sanitation protocols.
4. Interviewing Staff: Assessing staff knowledge of food safety regulations, their tasks, and their responsibilities.
5. Reporting: Summarizing findings, detailing non-conformities, and recommending corrective actions for improvement.

A Closer Look at Food Safety Audits

Food safety audits come in different forms, from in-house process checks to formal government inspections. 

No matter which type you face, all share one fundamental goal: ensuring safe, high-quality products that protect consumers and boost your brand’s credibility.

1. Internal Audits

▪️ Who Conducts Them? Your own staff or appointed internal auditors.

▪️ Why They’re Important 

Internal audits are your first line of defense, helping you pinpoint and resolve potential issues long before an external party arrives. 

By reviewing hygiene practices, record-keeping, and equipment upkeep in-house, you nurture a culture of accountability and continuous improvement.

▪️ Focus Areas

• Day-to-day hygiene and sanitation

• Accurate documentation and record-keeping

• Equipment maintenance cycles

• Adherence to internal safety protocols

2. Supplier Audits (Second-Party Audits)

▪️ Who Conducts Them? Your company audits its suppliers.

▪️ Why They’re Important

By vetting your suppliers, you ensure that raw materials arrive safe and compliant, minimizing the chance of introducing hazards downstream. 

These audits confirm that suppliers uphold your required safety and quality criteria, preventing small lapses at the source from snowballing into larger, more costly problems.

▪️ Focus Areas

• Supplier compliance with your safety standards

• Quality and traceability of raw materials

• Alignment with your internal protocols and certifications

3. Regulatory Audits

▪️ Who Conducts Them? Government agencies such as the FDA, USDA, or local health departments.

▪️ Why They’re Important

Regulatory audits verify that your processes meet legal requirements, such as those under the FDA’s FSMA. Passing these inspections not only prevents fines and penalties but also reassures your customers and partners that your operation meets (or exceeds) official standards.

▪️ Focus Areas

• Compliance with national and regional laws

• Proper food handling, storage, and labeling practices

• Complete, accurate documentation of safety measures

4. Third-Party Audits

▪️ Who Conducts Them? Independent bodies like those under the Global Food Safety Initiative (GFSI), Safe Quality Food (SQF), or ISO 22000 certification.

▪️ Why They’re Important

Third-party audits offer an unbiased evaluation of your food safety management systems. Achieving these certifications can significantly enhance your brand reputation and open doors to partnerships with major retailers who often mandate recognized seals of approval.

▪️ Focus Areas

• Compliance with stringent industry standards

• Certification prerequisites (e.g., SQF or ISO 22000 requirements)

• In-depth review of management systems, record-keeping, and continuous improvement efforts

What Are Key Components of a Food Safety Audit – Checklist

Although the specific requirements can vary based on the standard or regulation being audited against, most food safety audits typically include these fundamental components:

1. Documentation Review

• HACCP Plans: Ensure they’re comprehensive and up-to-date.

• Sanitation Standard Operating Procedures (SSOPs): Confirm alignment with actual cleaning practices and frequency.

• Training Records: Validate that training is timely, relevant, and well-documented.

• Supplier and Incoming Goods Records: Track origins, certificates of analysis, and any relevant safety documentation.

2. On-Site Inspection

• Facility Layout and Flow: Assess if the design prevents cross-contamination (e.g., separation of raw and cooked areas).

• Equipment Functionality: Verify proper temperature controls, calibration of thermometers, and equipment maintenance.

• Storage and Inventory Management: Check if items are stored at correct temperatures, properly labeled, and regularly rotated.

3. Interviews and Observations

• Staff Knowledge: Are employees aware of critical points, sanitation procedures, and emergency protocols?

• Personal Hygiene Practices: Observe handwashing frequency, use of protective clothing (gloves, hairnets), and any relevant policies (e.g., jewelry restrictions).

• Operational Flow: Confirm that actual processes match documented procedures (e.g., cleaning cycles, temperature logs).

4. Reporting

• Audit Findings: Detailed list of observations, positive practices, and non-conformities.

• Corrective Actions: Specific, actionable recommendations and timelines for resolving issues.

• Follow-Up Plan: Strategy and schedule for ensuring improvements remain in place.

How to Conduct a Food Safety Compliance Audit

1. Preparation

1. Understand the Standards

Before starting, confirm which regulatory or certification standards apply to your business. 

If your facility is in the U.S., you might focus on FDA FSMA rules; an international facility could adhere to ISO 22000, BRC, SQF, or other recognized schemes. 

Research these thoroughly so you know the criteria and scope of the upcoming audit.

2. Document Everything

One of the most common non-conformities in audits is incomplete or inconsistent documentation. 

Ensure every step of the process is written out, including:

• HACCP Plans

• Standard Operating Procedures (SOPs) for cleaning, pest control, labeling, packaging, etc.

• Training Logs showing employees have current, job-specific training.

• Equipment Maintenance Logs confirming that calibration and servicing are done as scheduled.

Keep these documents organized and readily accessible. 

Also, don’t forget to have digital backups (using a Food Safety Management Software), which can also streamline the audit process.

3. Conduct Internal Audits

Regular internal self-checks will help identify problem areas. 

You may also consider inviting a third-party consultant for a “test audit” before the official one. Internal audits should focus on:

• Reviewing procedures and policies to ensure they align with day-to-day operations.

• Checking critical control points (CCPs) for consistent monitoring and recording.

• Inspecting facility cleanliness and maintenance.
  
  
  

Below is a sample internal audit preparation checklist:

2. Audit Execution

1. Create an Audit Schedule

Divide the audit into manageable sections: documentation review, physical inspection, staff interviews, and record analysis. 

Clearly communicate the schedule so staff can prepare and operations aren’t excessively disrupted.

2. Inspect Facilities and Processes

Check each area in the production and storage process thoroughly:

• Receiving Bay: Are deliveries checked for temperature and quality upon arrival?

• Storage: Are items labeled with correct expiry dates and stored under appropriate conditions (e.g., refrigerated, frozen, or ambient)?

• Processing and Handling: Are surfaces sanitized between product runs? Is there any risk of cross-contamination?

• Packaging and Labeling: Are labels accurate and compliant with regulations (allergens, expiration date)?
  
  
  

Use a structured template to remain consistent. Here’s a brief facilities and processes inspection table example:

3. Observe Employee Practices

Proper employee training is critical to food safety:

• Personal Hygiene: Are employees washing their hands properly and wearing required protective clothing (hairnets, gloves, face masks)?

• Handling Procedures: Do they follow designated allergen controls to avoid cross-contact?

• Record Keeping: Are temperature logs, cleaning records, and equipment checks updated in real time?

Remember to encourage employees to ask questions and clarify procedures if they are uncertain about anything. An engaged workforce is more likely to be audit-ready at all times.

3. Risk Identification and Mitigation

1. Hazard Analysis

Regularly pinpoint each potential risk – whether biological (e.g., pathogens), chemical (like allergens or sanitizers), or physical (sharp fragments, foreign objects) – at every stage of production. 

This ongoing vigilance is central to HACCP and must be woven into daily operations rather than reserved solely for audits.

2. Critical Control Points (CCPs)

Pinpoint where hazards can be prevented, eliminated, or reduced to acceptable levels. Examples of CCPs:

• Cooking Temperature: Ensuring product reaches the required internal temperature to kill pathogens.

• Chilling: Rapid cooling to maintain safe temperature ranges.

• Metal Detection: Scanning finished products to detect foreign objects.

Ensure each CCP has clear operating limits, monitoring procedures, corrective actions for deviations, and detailed documentation.

3. Corrective Actions

When a CCP limit is exceeded (e.g., storage temperature above acceptable range), be ready to quarantine the product, adjust the process, or conduct additional tests. 

Document each action and train staff to handle these situations promptly.

4. Reporting and Follow-Up

1. Compile Audit Findings

After the inspection, organize observations into a formal audit report:

• Areas of Good Performance: Recognize strengths and best practices to reinforce positive behavior.

• Non-Conformities: Clearly outline each issue found, referencing the specific standard or policy it violates.

• Corrective Action Plan: Assign responsibilities for each action, outline deadlines, and define verification procedures.

2. Implement Corrective Actions

Implement improvements swiftly, especially for high-risk issues. This may include:

• Updating SOPs: If staff are consistently missing a step, refine or clarify the procedure.

• Additional Training: Address knowledge gaps by scheduling refresher courses or skill-building workshops.

• Process Redesign: If a hazard repeatedly occurs at the same point, reevaluate workflows or facility layout to eliminate risk.

3. Continuous Monitoring

Document your progress in closing gaps. Maintain updated logs, photos, or test results to show how each non-conformity was resolved. This proof will be crucial during follow-up audits or external regulatory inspections.

5. Continuous Improvement

Food safety is not a “set it and forget it” endeavor. Ongoing efforts ensure that your business remains compliant and prepared.

• Regular Audits: Conduct at least one comprehensive internal audit each year, plus targeted audits when introducing new products or processes.

• Staff Training and Engagement: Host regular stand-up meetings to reinforce key food safety concepts. Provide refresher training whenever policies or regulations change.
  Stay Current on Regulations: Monitor updates from regulatory bodies (FDA, USDA, EFSA, etc.) and certification schemes (BRC, SQF, ISO).

• Technology and Automation: Consider using food safety apps or software to track documentation, automate temperature logging, and manage corrective actions. Implement advanced solutions like virtual reality (VR) training modules or mobile apps that simulate real-world scenarios.

• Pest Management: Periodically verify the effectiveness of pest control measures. Pest infestations are a common non-conformity.

• Supplier Audits: Extend your auditing program upstream, ensuring that raw materials are sourced from reputable, compliant suppliers.

How To Train Staff for a Successful Audit

1. Foster a Dynamic Food Safety Culture

▪️ Empower Employee Ownership

Encourage everyone – from entry-level staff to senior supervisors – to call out potential risks or process flaws the moment they notice them. Reinforce that flagging issues is a strength, not a shortcoming.

▪️ Lead by Example

Managers and executives should visibly champion food safety, allocating the time, budget, and tools employees need to stay compliant. When leaders prioritize safe practices, the entire team follows suit.

2. Use Effective Training Methods

▪️ Short Classroom Sessions (60–90 minutes)

Use focused, interactive lessons to dive into essential theory, such as allergen management or basic HACCP principles. Incorporate real-world scenarios or case studies to illustrate potential risks and solutions.

▪️ On-the-Job Training (OJT)

Pair less-experienced employees with seasoned mentors. Show them precisely how to sanitize surfaces, monitor temperatures, or calibrate equipment in the actual work environment. Immediate feedback cements proper habits faster than any manual can.

▪️ Stand-Up Trainings (10–15 minutes)

Schedule quick, targeted “huddles” to reinforce one principle at a time – like the correct way to use gloves or how to segregate allergens. Frequent, bite-sized lessons keep essential protocols top-of-mind without disrupting workflow.

▪️ Mock Audits

Simulate the real audit process with unannounced walk-throughs or staged questions. This keeps everyone “audit-ready” and reveals blind spots, which is ideal for refining SOPs before an official inspection.

3. Ensure Your Training Sticks

▪️ Quizzes & Spot Assessments

Test team knowledge regularly, whether through simple paper quizzes or quick digital polls. Short, periodic evaluations help you track who’s retaining critical information and who might need extra coaching.

▪️ Observe & Provide Feedback

Spend time on the floor, watching how tasks are done in practice. Offer constructive pointers on the spot. Real-time coaching is often more impactful than waiting for a formal review.

▪️ Document, Document, Document

Keep updated training logs to show who was trained, when, and on what. Not only does this prove compliance during audits, but it also helps you spot trends like which topics need more frequent refreshers.

Common Non-Conformities and How to Avoid Them

How Often Should a Food Safety Compliance Audit Be Conducted?

The frequency of audits depends on factors such as regulatory requirements, risk level of products (e.g., ready-to-eat vs. shelf-stable), and company policies. 

Many food businesses conduct annual external audits (e.g., for certifications) alongside quarterly or semi-annual internal audits.

In high-risk operations or after major process changes, more frequent audits may be warranted to ensure full compliance.
