What is PRP, OPRP, and CCP in food safety
Share
In food safety, particularly under the framework of Hazard Analysis and Critical Control Points (HACCP), there are several key concepts: PRP (Prerequisite Programs), OPRP(Operational Prerequisite Programs), and CCP(Critical Control Points). These elements are critical in managing food safety hazards.
1. PRP (Prerequisite Programs)
Definition:
PRPs are the basic environmental and operational conditions that are essential for maintaining food safety. They provide the foundation upon which a food safety management system is built. PRPs address the general hygiene and environmental conditions necessary for producing safe food.
Key Focus:
- Infrastructure (building and equipment)
- Pest control
- Supplier control
- Personnel hygiene
- Sanitation procedures
- Storage and transportation
Industrial Example:
In a dairy plant, a PRP would be maintaining the cleanliness and sanitization of the equipment used in milk processing, like the cleaning of pipes and tanks. Regular pest control checks and implementing hygiene protocols (such as hand washing, wearing protective gear) are also critical in ensuring that no external contaminants affect the production environment.
2. OPRP (Operational Prerequisite Programs)
Definition:
OPRPs are specific control measures or actions that significantly reduce the risk of food safety hazards, but they do not completely eliminate the hazard. They are more focused and critical than PRPs but not as rigorous as CCPs. OPRPs help manage identified significant hazards that are not fully controlled by CCPs.
Key Focus:
- Control measures for hazards that may occur during processing
- Focused on reducing contamination or hazard introduction at critical points
Industrial Example:
In a bakery, an OPRP might be the use of metal detectors at various stages of production to ensure that no metal fragments are present in the bread. While this is not the final control (as that might happen at a CCP), it helps significantly reduce potential risks.
Another example in a beverage plant could be regular monitoring of water filtration systems to ensure that no contaminants enter the production process. This is an ongoing control measure to reduce microbial or chemical hazards.
3. CCP (Critical Control Points)
Definition:
CCPs are steps or stages in the food production process where control measures can be applied to prevent, eliminate, or reduce a food safety hazard to acceptable levels. Unlike PRPs and OPRPs, CCPs are points where failure to control the hazard will likely result in a food safety issue.
Key Focus:
- Specific to the product and process
- Directly affects food safety
- Measurable and monitorable parameters (temperature, pH, etc.)
Industrial Example:
In the production of cooked meats, a CCP could be the cooking process itself, where the temperature is monitored and controlled to ensure the elimination of harmful bacteria such as Salmonella or E. coli. The critical limit might be cooking the meat to an internal temperature of 74°C for a specific amount of time.
In the canned food industry, the CCP is typically the sterilization process. During this step, the cans are heated to a temperature and pressure that destroys any potential microorganisms, such as Clostridium botulinum. The temperature and time are continuously monitored to ensure the process is effective.
