Hazard > Risk
Risk = Hazard x Chance
Risk means: a function of the probability (chance)
of an adverse health effect and the
severity (DALY) of that effect,
consequential to the hazard

Perception of Risks 1
When do I fear something? Fear is used to become most close to your feeling.
1. Free will or “must”? (reception and walking home)2. Own influence? (taxi passenger) (Accidents)3. Is it visible? Can I see it with my eyes? (Caterpillars - residues)4. Do I have power over it? (Building nearby)5. Well known or new? (Internet pay)

Perception of Risks 2
6. Here or there? (tsunamie)7. Local or in a wide area (escape avoidable)8. Do I know what I see? (cooling tower)9. Small or large? (industrial – workshop)10. Once or is repetition to be expected? ( traffic noise?)11. Does it harm? (smell)12. Can I flee or go to another place? Avoid it?13. To what scale can the disaster grow? (influenza)14. Inherited?

Specific questions on food:– 60% - 70% concerns on contaminants and intoxications– Not preparing at home!

Risk Framework
19
Risk Assessment
Hazard identification: The identification of health effects associated with a particular agent. Hazard characterization: The nature of the adverse effects associated with biological, chemical, and physical agents which may be present in food.
20
Risk Assessment
Exposure assessment: The evaluation of the degree of intake likely to occur.
Risk characterization: Integration into an estimation of the adverse effects likely to occur in a given population.
21
Risk Assessment
After assessment we know the
“Ins” and “outs” of the hazard.
Based on the characterisation we cen
proceed to
Risk Management
22
Risk Management
– weighing policy alternatives to– accept, minimize or reduce risks and – to select and implement appropriate
options.
23
Risk Management
Steps to run through:– Preliminary activities– Evaluation of options– Decision and implementation of measures– Monitoring and review
24
Risk Management
Preliminary risk management activities It includes the establishment of a risk profile to facilitate consideration of the issue within a particular context, and provides as much information as possible to guide further action.
As a result of this process, the risk manager may commission a risk
assessment as an independent scientific process to inform decision-making.
SCIENTIFIC PROCESS
25
Risk Management Evaluation
Evaluation of risk management options Weighing of available options - in light of scientific information on risks and other factors, and may include reaching a decision on an appropriate level of consumer protection. Optimization of food control measures in terms of efficiency, effectiveness, technological feasibility and practicality
A cost-benefit analysis could be performed at this stage.
26
Risk implementation
Implementation of the risk management decision
involve regulatory food safety measures, which may include the use of HACCP.
Flexibility in the choice of individual measures applied by industry is a desirable element, as long as it can be objectively shown to achieve the stated goals.
27
Risk monitoring review
Monitoring and review
is the gathering and analyzing of data so as to give an overview of food safety and consumer health.
Monitoring of contaminants in food and foodborne disease surveillance should identify new food safety problems as they emerge. Where there is evidence that required public health goals are not being achieved, redesign of food safety measures will be needed.
28
Risk Communication
– Information– Adapted to the group concerned– Actions taken to avoid/eliminate the hazard
NOT aeroplaneThis is you captain speaking: “The left wing engine
is on fire, the right wing engine is on fire, but don’t worry everything is under control”

Risks how to handle ?
Apply HACCP 7 steps1. Identify Hazards2. Identify critical control points (CCP)3. Establish critical limits4. Monitoring at CCPs5. Corrective actions6. Procedures to verify the effectiveness of the measures7. Documentation of the above

Risks how to handle ?
– Obtain ingredients from known suppliers– Ask for guarantees– Perform own controls at delivery– Processing – Packaging– Labelling– Transport– Storage– Preparation
