Sanitation Preventive Controls: When Are They Required and How Should They Be Verified?

A sanitation procedure and a sanitation preventive control are not automatically the same thing. For facilities subject to the preventive controls for human food requirements under 21 CFR Part 117, the hazard analysis establishes which hazards require a preventive control. Sanitation preventive controls are required when appropriate to significantly minimize or prevent identified hazards, such as certain environmental pathogen or allergen cross-contact hazards. This distinction helps teams avoid both under-controlling significant risks and creating unnecessary paperwork.

Begin with the written hazard analysis

Assess the food, processing environment, raw materials, activities, reasonably foreseeable hazards and intended use. Decide which hazards require preventive controls and document the rationale. Evaluate the hazard in the context of the facility instead of assuming every cleaning activity qualifies as a preventive control.

Define the control and its purpose

Where a sanitation preventive control is appropriate, describe how the activity reduces the hazard. It may address cleanliness of food-contact surfaces, cross-contamination pathways, employee practices, or allergen cross-contact. Procedures should be understandable and executable by responsible personnel.

Apply management components appropriate to the control

Establish monitoring, corrective actions, and verification as required and appropriate to the nature of the control and its role in the food safety system. Monitoring and verification do not always look like time-and-temperature control records; they must be designed for the specific sanitation measure.

Consider environmental monitoring when applicable

FDA explains that environmental monitoring is required when contamination of a ready-to-eat food with an environmental pathogen is a hazard requiring a preventive control. The sampling strategy and related response procedures should reflect the facility, product, hazard, and control strategy.

Clarify the PCQI’s role

A preventive controls qualified individual performs or oversees required food safety plan activities under the rule. FDA recognizes qualification through appropriate training or equivalent job experience; completion of a particular branded training course is not the sole route to qualification.

What should your facility do next?

A well-developed sanitation preventive control program should make it possible to answer five questions: What hazard is controlled? Why is this control needed? Who performs it? How is it monitored and verified? What happens when the control does not work as intended?
