RISK DEFINED RISK is a Function of Probability of an adverse health effect and the severity of that effect,
consequential to a HAZARD(s) in food.

Exposure assessmentQualitative and/or Quantitative Evaluation Of • the likely Intake of Hazardous Agents via food Or other source if relevant.
Risk characterizationQualitative and/or Quantitative Estimation of• Attendant uncertainties• The probability of occurrence• Severity of known or potential adverse health effects
in a given population depending on above three steps

RISK ASSESSMENT SHOULD TAKE INTO ACCOUNT
Relevant production ,storage and handling practises
Used throughout the food chain. It should include traditiional practises,methods
of Analysis,sampling,inspection and the
prevalence of specific adverse health effects.

RISK MANAGEMENT Weighing policy alternatives in the light
of the results of risk assessment. Selecting and implementing
appropriate control options,including regulatory measures.
Note:Major concern human health cosideration.

HACCP SYSTEM
HAZARDANALYSIS CRITICAL CONTROL POINT
![Page 12: Risk analysis and HACCP System](https://reader034.vdocuments.mx/reader034/viewer/2022042601/541659178d7f72336c8b4a62/html5/thumbnails/12.jpg)
HACCP is a system which Identifies, Evaluates and Control hazards , significant for food safety.

Evolution of HACCP System

EVOLUTION OF HACCP SYSTEM Developed for micro biological
food safety of ASTRONAUTS
Original system Drawn up by Pillsbury Company
working with NASA and the US military

HACCP Terminology
![Page 16: Risk analysis and HACCP System](https://reader034.vdocuments.mx/reader034/viewer/2022042601/541659178d7f72336c8b4a62/html5/thumbnails/16.jpg)
HACCP TERMINOLOGY 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.
CRITICAL LIMITThe value of a monitored action which
separates the acceptable from unacceptable.
![Page 17: Risk analysis and HACCP System](https://reader034.vdocuments.mx/reader034/viewer/2022042601/541659178d7f72336c8b4a62/html5/thumbnails/17.jpg)
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.
![Page 18: Risk analysis and HACCP System](https://reader034.vdocuments.mx/reader034/viewer/2022042601/541659178d7f72336c8b4a62/html5/thumbnails/18.jpg)
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.
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.

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.
![Page 20: Risk analysis and HACCP System](https://reader034.vdocuments.mx/reader034/viewer/2022042601/541659178d7f72336c8b4a62/html5/thumbnails/20.jpg)
7-HACCP Principles
![Page 21: Risk analysis and HACCP System](https://reader034.vdocuments.mx/reader034/viewer/2022042601/541659178d7f72336c8b4a62/html5/thumbnails/21.jpg)
7-HACCP PRINCIPLES1. Conduct Hazard Analysis-
Process flow diagram. Identify hazards and Preventive measure
2. Determine CCP’s in process Establish the points where control is critical to mange the
safety of the product.3. Establish critical limits for preventive
measures associated with each identified CCP
The critical limits describe the difference between safe and unsafe product at the CCPs
These must involve a measureable parameter and may also known as the absolute tolerance for the CCP
![Page 22: Risk analysis and HACCP System](https://reader034.vdocuments.mx/reader034/viewer/2022042601/541659178d7f72336c8b4a62/html5/thumbnails/22.jpg)
4. Establish a system to monitor control of the CCP.
Specify monitoring requirements for management of the CCP within its critical limit.
It involves specifying monitoring actions along with frequency and responsibility.
5. Establish the corrective action to be taken when monitoring
Act to bring the process back under control. Act to deal with product manufactured while the
process was out of control.

6. Establish procedures for verification to
confirm that the HACCP system is working effectively
7. Establish documentation concerning all
procedures and records appropriate to these principles and their application.

APPLICATION STAGES OF HACCP
Determine the terms of reference Assemble and Train
the HACCP teamDescribe the processes/products Identify intended useConstruct flow diagram
On-ste verification of flow diagramList all potential hazards
Conduct a Hazard analysisDetermine control measures
Determine CCPsEstablish critical limit for each CCP
Establish a monitoring system for each CCP
Establish Corrective Action for Deviations that may occurEstablish Verification Procedures
Establish record keeping and DocumentationReview the HACCP plan
