7 Principles of HACCP
HAZARD ??? A biological, chemical, or physical agent in food with the potential to cause an adverse health effect (Codex, 1997). Hazard: MicrobiologicalMicrobiological ChemicalChemical PhysicalPhysical Food-borne disease (FBD): penyakit menular atau keracunan yang oleh mikroba atau agen yang masuk ke dalam tubuh melalui makanan yang di konsumsi (WHO).
Principle 1: Hazard analysis The process of collecting and evaluating information on hazards and conditions leading to their presence to decide which are significant for food safety and should be addressed in the HACCP plan. The process of collecting and evaluating information on hazards and conditions leading to their presence to decide which are significant for food safety and should be addressed in the HACCP plan.
Information needed for hazard analysis the agents that could be present in the food under study the severity of the effects and the likelihood of their occurrence the levels that could cause adverse health effects the conditions that could lead to unacceptable levels
Microbial Hazards Dangerous microorganisms that cause food-borne disease (FBD): Dangerous microorganisms that cause food-borne disease (FBD): –Bacteria –Moulds –Viruses –Parasites
Patogenic microorganisms are the MAJOR SOURCES of food contamination!!!
Some toxigenic moulds causing FBD Aspergillus spp Fusarium spp. Penicilium spp Producing mycotoxins, such as aflatoxin, ochratoxin, etc. Main sources: fruits, nuts and grains
Major viruses causing FBD Hepatitis A and E viruses Hepatitis A and E viruses Small round structured viruses (e.g. Norwalk) Small round structured viruses (e.g. Norwalk) Rotavirus Rotavirus Polio virus Polio virus

Hazard Determination Is the presence of agent in raw material probable? Is the presence of agent in line or environment probable? Is an unacceptable survival, persistence or increase at this step probable? Is an unacceptable contamination at this step probable? Is reduction, if any at a further step adequate? YES No Hazard NO HAZARD

Principle 2: determine the CCPs CCP: CCP: a step at which control can be applied and the step is essential to prevent and eliminate a food safety hazard or reduce it to an acceptable level (Codex 1997). CCPs relate to control of significant food safety hazards only. CCPs relate to control of significant food safety hazards only.
2. Determination of CCPs Q1. Is it likely that the raw material contains the hazard under study at unacceptable levels? Q2. Will processing, including expected consumer use, eliminate the hazard or reduce it to an acceptable level? Critical control point decision tree Questions to be asked for each raw material used Questions to be asked for each raw material used YES NO YES Not CCP CCP for the raw materials for this hazard
Questions to be asked for each process stage (SNI, 1998)
Control Measure Any factor or activity which can be used to prevent, eliminate, or reduce food safety hazards to an acceptable level. Any factor or activity which can be used to prevent, eliminate, or reduce food safety hazards to an acceptable level. Control measures are specific for each hazard and can be either process or activities. Control measures are specific for each hazard and can be either process or activities.
Control Measures Biological Hazards Control Measures Vegetative pathogens: Salmonella, Listeria monocytogenes, E.coli. Heat stable pre-formed toxins: S.aureus, B. cereus - Lethal heat treatment during packaging - Temperature control - Intrinsic factors: pH, aw - Intact packaging - Secure building, etc. - effective supplier process and testing - hand wash procedures - control of time
Control Measures Chemical Hazards Control Measures Cleaning chemicals Chemical additives - Use of non-toxic, food compatible cleaning compounds - separate storage - covered containers - Safe operating practices - written additive instructions - validation of levels through usage rates, sampling and testing
Control Measures Physical Hazards Control Measures Glass, wood, metal, etc in raw materials. Physical process cross- contaminants: pests - inspection – electronic or human - Washing - Air separation - X-ray detection - Metal detector, etc. - Pest control - Extermination (electric pest killers, poisoning, bait boxes, etc).
Critical Limit(s) CL are the criteria that differentiate between ‘safe’ and ‘unsafe’ safety boundaries. CL are the criteria that differentiate between ‘safe’ and ‘unsafe’ safety boundaries. Codex (1997): “a criterion which separates acceptability from unacceptability.” Codex (1997): “a criterion which separates acceptability from unacceptability.” Defined by regulations, safety standards and scientifically proven values. Defined by regulations, safety standards and scientifically proven values. Operational limits are often set a more stringent levels to provide a buffer or action zone for process management. Operational limits are often set a more stringent levels to provide a buffer or action zone for process management.
Critical limits can be: Critical limits can be: Values of pH, aw, temperature, time Absorbed radiation dose Levels of disinfectant or antimicrobial agents Level of cleanliness Limits of residues Limits of contaminants Limits of microbiological criteria Sensory parameters: visual appearance and texture Critical Limit(s)
Buffer or action zone, for example: Buffer or action zone, for example: If in a heat process the critical limit is 72 o C for 2 minutes, the operating limit of 75 o C for 10 min may be set. Critical Limit(s)

When is deviation from normality unacceptable? ( i.e. establishment of Critical Limits )
Monitoring Observation or measurement required to ensure that the process is under control operating within the defined critical limit ensuring that control measures are working. Codex (1997) defined monitoring as “ the act of conducting a planned sequence of observations or measurements of control parameters to assess whether a CCP is under control”.
Monitoring of the CCPs is carried through tests or observations The frequency and responsibility for monitoring will be appropriate to the control measure. The frequency of monitoring will depend on the nature of the CCP and must be determined as part of the control system. All personnel responsible for monitoring must be trained and have a clear understanding of their role. Monitoring
Equipment and methods: Equipment and methods: Physical parameters: temperature, time, moisture levels, metal detection, X-ray detection, inspecting sifters, and sieves. Chemical test: chlorine analysis, pH, aw, pesticide residue analysis, allergen residue testing, heavy metals analysis. Sensory test: visual appearance, texture. Monitoring
The equipment used for monitoring must be: The equipment used for monitoring must be: Accurate: needs to be calibrated. Easy to use Accessible: having the equipment close to the point of testing and must be quick in terms of providing results. Monitoring
People assigned monitoring duties should be: People assigned monitoring duties should be: Familiar with the process Trained in the monitoring techniques Trained in HACCP awareness Unbiased in monitoring and reporting Trained in the corrective action procedures: what to do when monitoring indicates loss of control Monitoring
–The action should be taken when the result shows a deviation from the critical limit –Adjust the process to bring it back under control –Deal with the material produced under the deviation period Hold on the product Rework Release product after sampling and testing Direct into less sensitive products, e.g. animal feed –Clarify to all personnel involve (what to do and how to do it) Corrective Actions
The application of methods, procedures, tests, and other evaluations, in addition to monitoring, to determine conformity with the HACCP plan. Verification is on going activities (Codex, 1997) Verification
Review of HACCP system and records – –Review of unacceptable deviations and their follow up – –Confirmation that CCPs are controlled Review of consumer complaints End-product testing Review of validation data Verification
Whenever a change from the existing situation is made a new Hazard Analysis needs to be carried out, the outcome verified and the effectiveness of changes in the HACCP plan, if any, validated. Monitoring records, deviation files, raw material &end-product test results, customer complaints etc. need to be reviewed regularly. Records should be kept of all activities Verification
