Good Manufacturing Practices (GMP)

Good Manufacturing Practices (GMP) are the basic operational and environmental practices that help ensure food is produced, handled, stored and distributed safely and consistently. GMPs provide the foundation for a food-safety management system by controlling the conditions that could introduce contamination or undermine product quality.

Common elements of GMPs

• Premises and equipment: suitable building design, hygienic surfaces, maintained equipment, adequate lighting, ventilation and drainage.
• Personnel hygiene: handwashing, clean protective clothing, illness reporting and appropriate employee practices.
• Cleaning and sanitation: documented cleaning schedules, approved chemicals and verification of sanitation tasks.
• Pest control: prevention, monitoring and corrective action to keep pests away from food and food-contact areas.
• Receiving and storage: approved suppliers, inspection of deliveries, temperature control, stock rotation and protection from contamination.
• Process control: consistent recipes, production instructions, time-temperature controls and prevention of cross-contamination.
• Training and records: role-appropriate training, clear procedures and records that demonstrate required activities are completed.

GMPs in a professional kitchen

In a restaurant, GMPs are reflected in everyday practices such as storing raw poultry below ready-to-eat foods, using calibrated thermometers, cleaning and sanitizing food-contact surfaces, maintaining equipment and ensuring staff follow approved procedures. In food manufacturing, GMPs also cover product formulation, packaging, facility design and batch documentation.

GMPs versus HACCP

GMPs are foundational practices that support hygienic operations. HACCP is a systematic method for identifying and controlling significant food-safety hazards at defined points in a process. HACCP depends on effective prerequisite programs, which commonly include GMPs, sanitation and pest control.

Chef’s tip: Make GMP requirements practical and observable. Each procedure should identify who is responsible, what must be done, how often it happens and how the operation verifies completion.
