Why Sanitation Controls Are Essential to Preventive Food Safety

Sanitation Controls are a foundational element of any food safety system, directly addressing the risk of contamination from equipment, surfaces, and employees. For facilities where unsanitary conditions could contribute to hazards requiring preventive controls, the Food Safety Modernization Act (FSMA) mandates that a written Food Safety Plan includes these controls. The PCQI must oversee the development of the Food Safety Plan.

 When implemented effectively, sanitation controls can drastically reduce the risk of product recalls and build a culture of cleanliness and accountability across operations.

Step 1: Identify Areas and Practices Requiring Sanitation Controls

Sanitation controls apply to more than just cleaning schedules. They include specific, validated procedures that prevent cross-contamination from food contact surfaces, utensils, equipment, and employee practices.

Key areas that may require formal sanitation controls:

• Food contact surfaces and equipment
• Utensils and tools used in processing
• Employee hygiene stations and practices
• High-risk zones such as allergen handling or ready-to-eat (RTE) production areas

Actionable Tip: Perform a sanitation-focused facility risk assessment during your Hazard Analysis to identify where targeted controls are needed.

Step 2: Establish Written Sanitation SOPs and Protocols

Sanitation Standard Operating Procedures (SSOPs) form the backbone of your sanitation controls. These must be clearly written, validated for effectiveness, and designed for daily use.

Each SSOP should include:

• Cleaning frequency and responsibility
• Approved cleaning agents and chemical concentrations
• Step-by-step cleaning procedures
• Post-cleaning inspection or verification method
• Corrective actions for failures

Actionable Tip: Tailor SSOPs by zone or equipment type. Overly generic instructions reduce accountability and increase the chance of missed steps.

Step 3: Train and Equip Personnel

The success of sanitation controls depends heavily on frontline execution. The PCQI may play a key role in ensuring:

• Employees are trained on hygiene and sanitation procedures, including glove use, handwashing, and gowning.
• Sanitation teams are trained on chemical handling, safety data sheets (SDS), and cleaning protocols.
• Tools and PPE are readily available, stored hygienically, and replaced as needed.

Actionable Tip: Conduct hands-on training using actual cleaning equipment, not just classroom instruction. Reinforce expectations during facility walkthroughs.

Step 4: Monitor Sanitation Effectiveness

Ongoing monitoring of sanitation activities ensures that controls are working consistently. Monitoring procedures may include:

• Checklists and sign-off sheets for daily cleaning tasks
• ATP swab testing to measure organic residue on surfaces
• Microbiological testing (e.g., for Listeria or Salmonella in high-risk areas)
• Visual inspection by supervisors or QA staff

Actionable Tip: Use a sanitation log with timestamps, task descriptions, and initials to build traceability and accountability into your monitoring system.

Step 5: Verify, Validate, and Improve Sanitation Controls

Verification activities confirm that sanitation procedures are executed correctly, while validation ensures those procedures effectively control hazards.

Verification practices:

• Reviewing daily sanitation records and checklists
• Inspecting high-risk areas after cleaning
• Periodic internal audits focused on sanitation

Validation practices:

• Environmental testing for pathogens on surfaces and drains
• Testing of cleaning chemicals and dilution ratios
• Swab testing pre- and post-cleaning

Actionable Tip: Re-validate sanitation controls when introducing new equipment, processes, or facility layout changes.

Common Pitfalls in A Sanitation Controls Program

• One-size-fits-all SSOPs → Customize for specific zones, tools, or risks.
• Undertrained sanitation staff → Sanitation is often outsourced or delegated to junior staff; prioritize their training.
• Infrequent verification → Spot checks aren’t enough; build a scheduled verification process.
• Poor documentation → Incomplete or inconsistent logs will not stand up during FDA inspections.

Actionable Tip: Treat sanitation records with the same level of scrutiny as CCP logs—both are critical control points in FSMA compliance.

Make Sanitation a Cornerstone of Your Food Safety Plan

Sanitation controls are not just about cleaning—they’re about preventing contamination before it reaches the product line. The PCQI plays a central role in implementing scientifically sound procedures, training staff, verifying results, and continually improving the program.
