Risk analysis

  1. 1. RISK ANALYSIS<br />
  2. 2. RISK DEFINED<br />RISK is a Function of Probability<br /> of an adverse health effect and <br /> the severiety of that effect,consequential to <br /> a HAZARD(s) in food.<br />
  3. 3. COMPONENTS OF RISK ANALYSIS<br /> RISK ASSESSMENT<br /> RISK MANAGEMENT<br /> RISK COMMUNICATION<br />
  4. 4. RISK ASSESSMENTSTEPS<br /> HAZARD IDENTIFICATION<br /> HAZARD CHARACTERIZATION<br /> EXPOSURE ASSESSMENT<br /> RISK CHARACTERIZATION<br />
  5. 5. Hazard identification<br /> Biological<br /> Chemical <br /> Physical agents <br />Hazard characterization<br />Qualitative and/or Quantitative Evaluation <br /> Nature of adverse effects by agents<br /> Chemical agents-a dose response<br /> Physical and Biological-dose response if data present or obtainable <br />
  6. 6. Exposure assessment<br />Qualitative and/or Quantitative Evaluation Of <br /><ul><li>the likely Intake of Hazardous Agents via food</li></ul> Or other source if relevant.<br />Risk characterization<br />Qualitative and/or Quantitative Estimation of<br /><ul><li>Attendant uncertainties
  7. 7. The probability of occurrence
  8. 8. Severity of known or potential adverse health effects in a given population depending on above three steps</li></li></ul><li>RISK ASSESSMENT SHOULD TAKE INTO ACCOUNT<br />Relevant production ,storage and handling practises<br /> Used throughout the food chain.<br />It should include traditiionalpractises,methods of<br />Analysis,sampling,inspection and the prevalence of specific adverse health effects.<br />
  9. 9. RISK MANAGEMENT<br />Weighing policy alternatives in the light of the results of risk assessment.<br />Selecting and implementing appropriate control options,including regulatory measures.<br />Note:Major concern human health cosideration.<br />
  10. 10. RISK COMMUNICATION<br />It is the interactive exchange of information and opinions throughout the risk analysis process .<br /><ul><li>RISK

DIAGRAMMATIC REPRESENTATION OF RISK ANALYSIS PROCESS<br />RISK MANAGEMENT<br />Risk Evaluation<br />Option Assessment<br />Option Implementation<br />RISK ASSESSMENT<br />Hazard identification<br />Hazard characterization<br />Exposure Assessment<br />Risk Charcterization<br />RISK COMMUNICATION<br />
  15. 15. HACCP System<br />HAZARD<br />ANALYSIS <br />CRITICAL <br />CONTROL <br />POINT<br />
  16. 16. <ul><li>HACCP is a system which
  17. 17. Identifies,
  18. 18. Evaluates and
  19. 19. Control hazards ,</li></ul> significant for food safety.<br />
  20. 20. Evolution of HACCP System<br />Developed for micro biological food safety of ASTRONAUTS <br />Original system Drawn up by Pillsbury Company<br /> working with NASA and the US military<br />
  21. 21. HACCP Terminology<br />CCP-CCP is an operation(practice,process,procedure or location) at which a preventive or control measure can be exercised that will eliminate,prevent or minimize a hazard or several hazard.<br />CRITICAL LIMIT- The value of a monitored action which separates the acceptable from unacceptable.<br />CONTROL POINT-It is an operation at which preventive and/or control actions are taken because of good manufacturing practices,regulations,product reputation, corporate/company policies or aesthetics. Such distinction between CCP and CP are one of the unique features of HACCP System. This allows setting priorities on risk and emphasizes operations that offer the greatest potential for control.<br />
  22. 22. CORRECTIVE ACTION-It is a specified prompt action to be taken when the criteria are not met or when the results of monitoring the CCP indicates a trend towards loss of control.<br />VERIFICATION-Review of monitoring records to determine whether the HACCP system is in place and functioning as planned and to ensure that monitoring is carried out effectively and efficiently.<br />DECISION TREE-A sequence of Questions applied to each process step with a potential hazard to identify which process steps are critical to food safety.<br />
  23. 23. 7-HACCP Principles<br />1. Conduct Hazard Analysis-<br />Process flow diagram.<br />Identify hazards and Preventive measure<br />2. Determine CCP’s in process<br />Establish the points where control is critical to mange the safety of the product.<br />3. Establish critical limits for preventive measures <br /> associated with each identified CCP<br />The critical limits describe the difference between safe and unsafe product at the CCPs<br />These must involve a measureable parameter and may also known as the absolute tolerance for the CCP<br />
  24. 24. 4. Establish a system to monitor control of the CCP.<br />Specify monitoring requirements for management of the CCP within its critical limit.<br />It involves specifying monitoring actions along with frequency and responsibility.<br />5. Establish the corrective action to be taken when monitoring<br />Act to bring the process back under control.<br />Act to deal with product manufactured while the process was out of control.<br />
  25. 25. 6. Establish procedures for verification to <br /> confirm that the HACCP system is working effectively<br />7. Establish documentation concerning all <br /> procedures and records appropriate to these principles and their application.<br />
  26. 26. Application Stages of HACCP<br />Determine the terms of reference<br /> Assemble and Train the HACCP team<br />Describe the processes/products<br /> Identify intended use<br />Construct flow diagram<br /> On-ste verification of flow diagram<br />List all potential hazards<br /> Conduct a Hazard analysis<br />Determine control measures<br /> Determine CCPs<br />Establish critical limit for each CCP<br /> Establish a monitoring system for <br /> each CCP<br />Establish Corrective Action for Deviations that may occur<br /> Establish Verification Procedures<br />Establish record keeping and Documentation<br /> Review the HACCP plan<br />
