Good Manufacturing Practices (GMP) Good Manufacturing Practices (GMP) are guidelines that provide a system of processes, procedures, and documentation to ensure that the product has the identity, strength, composition, quality, and purity that it is purported to possess. In food manufacturing, this includes: Control of Operations: Standard operating procedures must be in place for all critical processes. For instance, in the production of canned foods, the cooking and canning temperatures and times must be precisely controlled and monitored. Equipment Maintenance: All equipment should be properly maintained and cleaned to prevent contamination. In a dairy, this means ensuring that pasteurizers are regularly checked and cleaned to prevent the buildup of harmful bacteria. Personnel Training: Workers must be trained on hygiene, procedures, and food safety related to their tasks. In a bakery, employees should be trained on the proper handling of ingredients to prevent cross-contamination with allergens. Facility Cleanliness: Facilities must be kept clean and in good repair. A meat processing plant, for example, must have a schedule for cleaning and sanitizing equipment and work areas to prevent the spread of pathogens like Listeria. Good Laboratory Practices (GLP) Good Laboratory Practices (GLP) are a framework of principles and procedures to be followed by laboratories that carry out testing and calibration regarding food samples. This includes: Sample Integrity: Proper collection, storage, and handling of food samples to prevent contamination or degradation. For instance, in testing for pesticide residues, samples must be stored at the correct temperatures until testing. Calibration and Validation: Regular calibration and validation of equipment used for testing. A food chemistry lab must regularly calibrate its spectrometers to ensure accurate nutrient analysis. Documentation: Comprehensive documentation of all testing procedures, results, and corrective actions. In a microbiology lab testing for Salmonella, all results, incubation times, and temperatures must be recorded. Personal Hygiene Personal hygiene is critical in food production and handling areas to prevent contamination: Hand Washing: Regular and thorough hand washing before and after handling food or food contact surfaces. For instance, in a sandwich shop, employees must wash hands between handling raw meats and ready-to-eat foods. Protective Clothing: Wearing appropriate protective clothing such as gloves, hairnets, and aprons. In a chocolate factory, workers should wear hairnets to prevent hair from contaminating the chocolate. Health Screenings: Regular health screenings for employees working in food handling. A seafood processing facility might screen workers for respiratory illnesses to prevent contamination. Good Handling Practices (GHP) Good Handling Practices (GHP) are the practices related to the handling, storage, and transportation of food intended to prevent food contamination and foodborne illnesses: Temperature Control: Maintaining proper temperatures during storage and transport. For example, fresh produce should be transported in refrigerated trucks to maintain freshness and prevent microbial growth. Cross-Contamination: Preventing cross-contamination between raw and cooked foods in kitchens. Cutting boards and knives used for raw chicken should not be used for vegetables served raw.  Pest Control: Implementing effective pest control measures in food storage areas. A grain silo, for example, must have measures in place to prevent infestations of rodents and insects. Legal Metrology Legal metrology pertains to the legal requirements regarding the measurements and measurement instruments used in commerce and industry: Label Accuracy: Ensuring that food product labels accurately reflect the weight or volume of the contents. Packaged snacks must be routinely checked to ensure they contain the weight listed on the packaging. Measurement Devices: Calibration and maintenance of measurement devices used in food production. Scales used in a deli must be calibrated regularly to ensure that customers are charged accurately for the weight of their purchases. Transparency: Compliance with legal requirements to inform consumers about food quantity, nutritional content, and pricing. Beverage manufacturers must ensure that the volume of drinks in bottles is accurately represented and compliant with stated volumes. Good Manufacturing Practices (GMP) Principles: Quality Control: Implementing procedures to ensure every product batch meets the required quality standards. Facility Design and Maintenance: Designing facilities to prevent cross-contamination between different food products. Equipment Maintenance: Ensuring equipment is regularly inspected and maintained to prevent malfunctions that could lead to product contamination.
