GMP and GHP provide systems to ensure proper design, monitoring and control of manufacturing processes and facilities when preparing food for human consumption. GMP principles include employee training, environmental monitoring, sanitation practices and allergen management. Key aspects of GMP in the food industry are personnel control, plant and grounds maintenance, sanitary operations, equipment and processes. Establishing GMP in the milk industry involves evaluating processing, raw materials, heat treatment, product standardization and transport. This improves quality, meets consumer needs, decreases losses and reduces environmental impact. GHP covers primary production, establishment design and maintenance, operations, transportation and consumer awareness to ensure food is safe and suitable at all stages of production.
