Preventive Control

A preventive control is a measure or action used to prevent a food-safety hazard, eliminate it or reduce it to an acceptable level before unsafe food reaches the consumer. Preventive controls may apply to ingredients, suppliers, equipment, personnel, processes, packaging, storage and distribution. The specific legal meaning varies by regulatory framework.

Examples of preventive controls

• Supplier approval: purchase ingredients from verified suppliers with suitable product specifications.
• Temperature control: maintain safe receiving, storage, cooking, cooling and holding conditions.
• Allergen management: identify allergens, control substitutions and prevent cross-contact.
• Sanitation: clean and sanitize food-contact surfaces using approved procedures.
• Employee hygiene: train staff in handwashing and illness reporting.
• Process controls: use validated recipes, time-temperature limits and monitoring procedures.

Preventive control versus corrective action

A preventive control is designed to stop or reduce a hazard before it causes harm. A corrective action is taken when a control fails or a deviation occurs. Both are necessary in a food-safety system.

Preventive controls and HACCP

HACCP identifies significant hazards and establishes controls, including critical control points where appropriate. Preventive controls may also include prerequisite programs such as supplier approval, sanitation, maintenance and employee hygiene. Some regulatory systems use “preventive controls” as a defined legal term with specific requirements.

Chef’s tip: Select controls that match the actual hazard and process. A general instruction to “be careful” is not a preventive control unless it is translated into a clear procedure that can be monitored and verified.

Key distinction: Preventive control is an action or measure to manage a hazard before harm occurs; it is not simply a response after a problem has been found.
