|PRP (Prerequisite Program)||CCP (Critical Control Point)||oPRP (Operational Prerequisite Program)|
|Definition||Basic conditions and activities necessary to maintain a hygienic environment throughout the food chain, suitable for the production of safe food.||A step in a food process at which control can be applied, and a food safety hazard can be prevented, eliminated, or reduced to acceptable levels.||A control measure that the hazard analysis identifies as necessary to control the likelihood of introducing food safety hazards or the contamination or proliferation of these hazards in the product(s) or the processing environment.|
|Purpose||Ensure a clean and safe environment for food production.||Specifically control identified hazards critical to food safety.||Control the likelihood of food safety hazards. Not necessarily critical, but essential in reducing the risk of specific hazards.|
|Example||Pest control, personal hygiene, cleaning and sanitation, training.||Cooking, cooling, reheating, specific cleaning procedures.||Steps like metal detection, sieving, specific temperature or humidity control in storage.|
|Identification in the industry||Determined by good manufacturing practices and do not usually require monitoring.||Identified through a HACCP study, typically require critical limits, monitoring, corrective action, verification, and record keeping.||Identified by the hazard analysis, often require validation, monitoring, corrective action, and record keeping, but usually do not have critical limits.|
What is an example of a PRP prerequisite program?
Who needs prerequisite programs? – Prerequisite programs are required for any type of food business, whether for food manufacturers or retail food stores. As long as you are dealing with wholesome food production, distribution, service, and even food retail, you would need to apply PRPs in your food operations.
- These programs include basic operations that help minimize contamination of products in food service operations and food processing plants.
- A good example of a PRP that applies to all food businesses is Good Manufacturing Practices.
- This PRP includes food operations such as proper personal hygiene, regular cleaning and sanitation procedures, food premises layout, and proper conduct during working hours.
The application of methods in PRPs is essential to creating a safe working environment. These sanitary conditions are for both the food employees and the safe food products they are handling. Loss of control over the subsequent steps of PRPs may lead to safety issues such as the contamination of products with rippling effects.

What is a prerequisite program in food safety?
APPENDIX A – Examples of Common Prerequisite Programs The production of safe food products requires that the HACCP system be built upon a solid foundation of prerequisite programs. Each segment of the food industry must provide the conditions necessary to protect food while it is under their control.
This has traditionally been accomplished through the application of cGMPs. These conditions and practices are now considered to be prerequisite to the development and implementation of effective HACCP plans. Prerequisite programs provide the basic environmental and operating conditions that are necessary for the production of safe, wholesome food.
Common prerequisite programs may include, but are not limited to: Facilities: The establishment should be located, constructed and maintained according to sanitary design principles. There should be linear product flow and traffic control to minimize cross-contamination from raw to cooked materials.
Supplier Control: Each facility should assure that its suppliers have in place effective GMP and food safety programs. These may be the subject of continuing supplier guarantee and supplier HACCP system verification. Specifications: There should be written specifications for all ingredients, products, and packaging materials.
Production Equipment: All equipment should be constructed and installed according to sanitary design principles. Preventive maintenance and calibration schedules should be established and documented. Cleaning and Sanitation: All procedures for cleaning and sanitation of the equipment and the facility should be written and followed.
- A master sanitation schedule should be in place.
- Personal Hygiene: All employees and other persons who enter the manufacturing plant should follow the requirements for personal hygiene.
- Training: All employees should receive documented training in personal hygiene, GMP, cleaning and sanitation procedures, personal safety, and their role in the HACCP program.
Chemical Control: Documented procedures must be in place to assure the segregation and proper use of non-food chemicals in the plant. These include cleaning chemicals, fumigants, and pesticides or baits used in or around the plant. Receiving, Storage and Shipping: All raw materials and products should be stored under sanitary conditions and the proper environmental conditions such as temperature and humidity to assure their safety and wholesomeness Traceability and Recall: All raw materials and products should be lot-coded and a recall system in place so that rapid and complete traces and recalls can be done when a product retrieval is necessary.
What is the difference between GMP and PRP?
GMP, PRP and HACCP – Although GMP, PRP and HACCP are specific elements, they have interfaces. GMP are general hygiene measures that need to be taken and they can be sector-specific or not. PRP will transform these hygiene measures into a practically manageable, effective and company-specific surveillance system.
- Furthermore, HACCP gives an additional clear and systematic analysis of the hazards that are specific for the company.
- After the completion of a company-specific hazard analysis, it will be clear, which process steps need supplementary specific control measures (CCP – Critical Control Point) in addition to the general control measures.
It can be stated that HACCP is necessary to concretise the GMP and PRR measures on one hand and to look for additional hazards through a company-specific study, to implement additional control measures on the other hand. However, when the PRPs are insufficient elaborated and implemented, a high number of hazards with a quite high chance of occurrence, need to be listed during the hazard analysis of HACCP.
- As a consequence, a lot of points will occur with high risks that are not controllable as a CCP.
- PRPs can be considered as the necessary foundation for a functional HACCP- system.
- The HACCP system is in its turn the ideal means to evaluate and adjust the existing PRP on the base of the hazard analysis.

What is the difference between PRP and PRP?
Understand the Differences Between PRP & PRF Injections If you’re considering treatments to improve the appearance of the skin around your eyes, you may have heard about PRP (Platelet-Rich Plasma) and PRF (Platelet-Rich Fibrin) injections. Both treatments use a patient’s own blood to stimulate the production of collagen and improve the overall appearance of the skin.
- However, there are some key differences between PRP and PRF injections that you should be aware of before making a decision.
- PRP is a treatment that involves injecting a concentration of platelets from the patient’s own blood into the skin.
- Platelets are a type of blood cell that contain growth factors, which can help stimulate the production of collagen and elastin, improve skin texture and tone, and reduce the appearance of scars and stretch marks.
PRF is similar to PRP, but it involves the use of a different preparation process that results in a higher concentration of platelets and a stronger release of growth factors. PRF also contains fibrin, a protein that helps to support tissue repair and regeneration.
PRP injections are created by isolating the platelets from a patient’s blood and concentrating them into a serum. This serum is then injected into the treatment area. PRF injections, on the other hand, are created by adding a fibrin matrix to the platelets, which creates a more cohesive and stable injectable product.
PRP injections are often used to improve the texture and tone of the skin and reduce the appearance of fine lines and wrinkles. PRF injections are typically used to improve the overall health and appearance of the skin and stimulate the production of collagen.
PRP injections tend to have a shorter duration of action compared to PRF injections. This means that the effects of PRP injections may not last as long as those of PRF injections. In conclusion, PRP and PRF injections are both effective treatments that can help improve the overall health and appearance of the skin, including in the under-eye area.

While they have some similarities, there are also some key differences that Nurse Gemavie can go over with you prior to your treatment. Nurse Gemavie is an experienced and compassionate nurse who specializes in regenerative aesthetics, she can help you understand the benefits and potential risks of each treatment and develop a personalized treatment plan to meet your needs.
Does PRP need FDA approval?
PRP Therapy Risks and Side Effects – A PRP injection is a low-risk procedure and does not usually cause major side effects. The procedure involves a blood draw, so you should make sure you are hydrated and have eaten beforehand to prevent feeling lightheaded.
Bleeding Tissue damage Infection Nerve injuries
If you are considering PRP injections, be sure to talk with your health care provider about all the benefits and risks. *Research for the different applications of PRP is promising and rapidly growing. Although the equipment used to produce PRP and the injections themselves have been cleared by the FDA, this procedure is considered investigational and has not been officially approved by the FDA for most uses.
How many PRP are required?
While more research is needed, PRP treatment for hair loss may help promote and maintain hair growth. PRP ( platelet-rich plasma ) therapy for hair loss is a three-step medical treatment in which a person’s blood is drawn, processed, and then injected into the scalp.
Some in the medical community think that PRP injections trigger natural hair growth and maintain it by increasing blood supply to the hair follicle and increasing the thickness of the hair shaft. Sometimes this approach is combined with other hair loss procedures or medications, There hasn’t been enough research to prove if PRP is an effective hair loss treatment.
However, PRP therapy has been in use since the 1980s. It’s been used for problems such as healing injured tendons, ligaments, and muscles. PRP therapy is a three-step process. Most PRP therapy requires three treatments 4–6 weeks apart. Maintenance treatments are required every 4–6 months.
What is meant by prerequisite program?
Prerequisite program. A procedure or set of procedures that is designed to provide basic environmental or operating conditions necessary for the production of safe, wholesome food. It is called prerequisite because it is considered by scientific experts to be prerequisite to a HACCP plan.
What is prerequisite requirement?
A prerequisite is a required prior condition. If something is required in advance of something else, like if you have to take a beginning Spanish class before signing up for Spanish II, then it’s a prerequisite.
What is the difference between HACCP and prerequisites?
Hazard Analysis and Critical Control Point (HACCP) identifies controls for specific hazards in the manufacturing, processing or handling process. Prerequisite Programs are programs to control hazards in the food manufacturing, processing or handling environment.
What is a prerequisite program in HACCP?
‘Prerequisites’ are basic hygiene measures that should be in place in your food business prior to you undertaking a HACCP study. They include matters such as supplier approval, incoming material specifications, finished product specifications and staff training.
The MyHACCP tool shows you a list of common prerequisites and asks you to select the ones you have properly considered and for which you have put in place adequate controls. You will then be invited to identify the location of documents such as policies and procedures where further details of these prerequisite controls may be found.
It is common for food businesses to place all these documents into a ‘prerequisite manual’ for ease of reference, but this is not a requirement. The list of prerequisites in MyHACCP is not exhaustive and there may be other matters, such as temperature control, which are relevant for your business.
- The title of the document. For example ‘Policy for glass and plastic management.’
- A brief statement on the purpose of the prerequisite measure. For example ‘To prevent contamination of products from glass or plastic from the factory environment.’
- What measures are necessary to achieve the desired outcome. For example, “No glass containers to be taken into production area.”
- Who will be responsible for ensuring that the requirements are met. For example, ‘Production supervisors must ensure that no glass containers are taken onto the production floor.’
- The nature and frequency of any checks that are to be made and by whom. For example, ‘Production supervisors must check the production area for any glass containers prior to commencing production each day.’
- What should happen if something goes wrong. For example, “Glass bottle found in production area. All staff provided with refresher training on glass policy to prevent recurrence.”
- How, where and by whom these checks are recorded. For example, ‘Production supervisors must record each pre-production glass check on form X1.’
- When and by whom the procedure must be reviewed for example, “This policy to be reviewed every 12 months by the Operations Manager.”
Top tip: Use the list of common prerequisites in MyHACCP as a checklist to ensure that you have properly considered all the relevant hygiene measures that should be in place before you start your HACCP study. Read about the general requirements for each prerequisite listed in the MyHACCP Web Tool.
What is the importance of PRPs during HACCP implementation?
Prerequisite programs make it easier to create a HACCP plan, allowing more time to focus on specific hazards introduced throughout the production process. Although certain aspects of prerequisite programs may be incorporated into a HACCP plan, they must be established and managed separately.
What is the difference between PRP and PPP?
PPP is a biologic treatment that is derived from your own blood. It is similar to platelet rich plasma (PRP) except that it has a lower concentration of platelet cells and growth factors. Medical literature has shown that some injuries such as muscle tears may heal better with PPP.
What are the PRP classification systems?
In PLRA classification, PRP is defined on the basis of platelet concentration (cells/μL), leucocyte content (>1% – positive or 1% – positive or
Who is PRP suitable for?
Who is eligible for PRP injections and what can they treat? – PRP is an orthopaedic treatment suitable for both sports injuries and degenerative conditions. It helps reduce pain and inflammation and improves healing and function. It can be used in all patients and in all age groups.
- Some sports-related injuries and degenerative conditions it is commonly used for are shoulder rotator cuff tears, shoulder impingement, elbow tendinitis, cartilage injuries, early to moderate osteoarthritis, patellar tendinopathy, and Achilles tendinopathy.
- PRP injections have been used as a main treatment and also in surgical augmentation procedures in which platelet-rich therapy was applied during surgery.
If conservative treatments such as pain killers and physiotherapy have failed to improve your symptoms, then PRP may be a good option for you. In my opinion it is better than using a steroid injection as steroids have side effects and risks and can potentially damage cartilage and tendons further.
What are the two types of PRP?
1. Introduction – Osteoarthritis (OA) is the most common form of arthritis, which affects the knee joint more often than the other joints in older people. The knee osteoarthritis (KOA) has become a major health concern because of the difficulties for its treatment.
Therefore, it is imperative to evaluate safe and effective treatment methods, and orthobiologics, representing a relatively new area of cell-based therapy, have captured the interest of orthopedic surgeons. Orthobiologics are natural substances, such as cells, blood components, and growth factors, which are used to promote the healing of soft and hard tissues such as muscle, cartilage, ligament, tendon, and bone tissues,
Among them, platelet-rich plasma (PRP)—an autologous platelet concentrate containing diverse growth factors such as platelet-derived growth factor (PDGF), transforming growth factor-beta (TGF-β), and vascular endothelial growth factor (VEGF) and other cytokines and enzymes exerting not only anabolic but also catabolic effects —has several advantages over other orthobiologics.
- It is a minimally-invasive, safe, and simple therapy that is associated with fewer side effects,
- Several types of PRP preparation kits are commercially available, which differ with respect to the methods of extraction, platelet, and other blood component concentrations.
- Therefore, it is very important to analyze the quality of PRPs for their use in orthobiological treatments.
Several randomized clinical trials, each using different PRPs, have revealed the effectiveness of PRP therapy for the treatment of KOA; however, the level of evidence was not high, Several studies have tried to characterize and classify PRPs. DeLong et al.
- Proposed the PAW classification system based on platelet concentration (P), activation status (A), and white blood cell concentration (W); whereas, Dohan Ehrenfest et al.
- Classified PRPs into three categories, leukocyte-rich (LR)-PRP, leukocyte-poor (LP)-PRP, and pure-PRP, based on the concentration of white blood cells.
The activities of PRPs have been shown to be dependent on cell compositions, and especially leukocyte concentrations, Moreover, LP-PRP has been hypothesized to be more suitable for intra-articular injection and is most frequently used than LR-PRP in the treatment of KOA,
Additionally, autologous protein solution (APS; dehydrated LR-PRP), a blood-derived, anti-inflammatory protein solution containing multiple anti-inflammatory cytokines as well as growth factors, prepared from a small sample of a patient’s blood, has been reported as an effective autologous treatment for osteoarthritis,
However, the differences in cell compositions and cytokine levels between APS and other PRPs have not been reported yet. Therefore, the present study was aimed to compare the quality of these two different types of PRPs, APS, and LP-PRP, with respect to cell composition and cytokine levels in HV.
What’s the difference between PRP and PRS?
PRP vs PRF —what’s the difference? – The difference between these treatments lies primarily in how your blood is collected prior to treatment. With PRP, your blood is spun in a centrifuge at high speed, completely separating the plasma layer. With PRF your blood is spun at a lower speed so that some of the white blood cells, stem cells, and fibrin remain in the platelet layer.
The slow spin also means fewer cells are damaged which leaves a higher concentration of healing platelets. PRF contains approximately 10 times the platelet concentration that is found within the body, whereas PRP contains roughly 2-5 times. Another notable difference is the use of anticoagulants. A PRP treatment is added to a vial containing anticoagulants, which prevent the blood from clotting during injection.
With PRF, no anticoagulants are added. This allows for the creation of a spongy fibrin matrix that signals the platelets to release their growth factors slowly. PRP releases growth factors for a few hours and PRF releases them for up to a week. This slow release is thought to have more robust, longer-lasting results.
What is PRP and what does it do?
Platelet-Rich Plasma (PRP) Injections Platelet-rich plasma (PRP) injections are gaining popularity for a variety of conditions, from sports injuries to hair loss. The treatment uses a patient’s own blood cells to accelerate healing in a specific area.
PRP treatment can help support wound healing in trauma and joint injury. The technique can address male pattern baldness, stimulate the growth of hair transplants and enhance other cosmetic procedures. The results of PRP treatment are most noticeable after several weeks for joint injections and six months for scalp injections, and are not permanent; patients may require additional injections at the direction of their doctor. Because the treatments use a patient’s own tissues, PRP injections are safe and can be administered alone or used in conjunction with other procedures.
Platelet-rich plasma consists of two elements: plasma, or the liquid portion of blood, and, a type of blood cell that plays an important role in healing throughout the body. Platelets are well-known for their clotting abilities, but they also contain growth factors that can trigger cell reproduction and stimulate tissue regeneration or healing in the treated area.
What is the difference between PRP and OPRP?
How is OPRP different from PRP? – A prerequisite program or PRP includes basic controls concerned with making a conducive and hygienic environment to create safe food. Most operations involved in this category are general and are not established to control a particular hazard.
- Their main objective is to ensure the fundamental conditions relating to proper hygiene conditions, suitability of equipment, cleaning, sanitation, and the production environment to reduce the risk of food safety hazards.
- The main difference between the two categories is that an OPRP is established to target a specific food safety hazard, whereas a PRP is a general operation.
Examples of PRPs include sets of general food safety practices in the food industry such as and the Sanitation Standard Operating Procedures. also include aspects such as the design and layout of the food establishment and employee facilities, food waste management, pest control, and food hygiene.
What is the difference between PRP and OPRP in food industry?
Quality Manager and Consultant, ISO 17025:2017, ISO 9001:2015, ISO 22000:2018, ISO 14001:2015, ISO 45001:2018, MQM – Published Nov 15, 2019 The Dilemma! Recently, still, there is a lot of confusion regarding the difference between OPRPs and CCPs in a food safety management system.
The difference between PRPs and CCPs are clear to most people as both are known parts of HACCP system since 1969, while the term OPRPs is still a little bit ambiguous among a lot of workers in the food sector. HACCP methodology uses the traditional concept of dividing control measures into two groups: prerequisites and measures applied at critical control points (CCPs).
In case of ISO 22000 that has been officially published for the first time in September 2005, these concepts are re-organized in a logical order by adding a group of control measures (CMs) named operational prerequisite programs (OPRPs). In order to clarify the difference between the three terms, we must first understand the classification of food safety hazards according to origin, and types of control measures.
Food safety hazard is a “biological, chemical or physical agent in food with the potential to cause an adverse health effect”. Types of Food safety hazards: Food safety hazards can be roughly classified into two types: 1- Type (A): Hazards originating from raw materials that must be eliminated or reduced to an acceptable level during the process of manufacturing/ catering.
Examples: · Salmonella in raw poultry and eggs. · E.coli in raw meat · Pseudomonas aeruginosa in source water · Foreign bodies in raw materials 2- Type (B): Hazards that can be introduced or worsened from the processing environment usually due to poor GMP conditions.
Examples: · Staphylococcus aureus from workers’ hands · Rodents · Introduction of foreign bodies from the environment due to poor GMP. Control measure (CM) is “an action or activity that is essential to prevent a significant food safety hazard or reduce it to an acceptable level”. Types of control measures: CMs can be classified into two types: 1- CMs applied at control points (CPs) along the process; e.g.: metal detector, pasteurization, sieving, etc.
These CMs are generally, but not entirely, used to control type A hazards that originate from raw materials.2- CMs applied at the process environment as general prerequisite programs (PRPs); e.g. pest control, personal hygiene, cleaning and sanitizing, etc.
- These CMs are generally used to control type B hazards that originate from the processing environment.
- The first type of control measures are generally applied at CCPs to prevent or reduce significant food safety hazard to an acceptable level while type two control measures are PRPs that are expected to be in place in advance.
The first type of CMs is risk based according to HACCP methodology while the second type is not. OPRPs is a new term emerged when ISO 22000 was published in 2005. It can be distinguished from CCPs and PRPs by the following definition: OPRPs are CMs or combination of CMs applied to control a specific type of hazard or group of hazards originating from the processing environment.
A brief comparison between the three terms are shown in Table 1. Summary OPRPs are special type of PRPs. They are applied to prevent or reduce significant food safety hazards originating from process environment. But, unlike regular PRPs, they do control specific hazards or specific group of hazards. The main difference between OPRPs and CCPs is that OPRPs are not based on critical control limits, but instead are based on action limit, and their failure don’t necessarily mean that the food product is unsafe.
