Slide 4 Section 2 – sub Module 5.1 - Control of Food Hazards
Effective controls prevent food safety hazards
Hazard = the potential to cause harmCodex defines hazard as a
• biological, chemical or physical agent in, or
• condition of,
food with the potential to cause an adverse health effect.

Slide 5 Section 2 – sub Module 5.1 - Control of Food Hazards
Deciding which hazards are of relevance in foods
Guidance material to help businesses understand which hazards are relevant to their foods is provided by authorities.

Slide 6 Section 2 – sub Module 5.1 - Control of Food Hazards
Controlling food hazards will reduce the risk of unsafe food
Risk = likelihood of a hazard doing harmFAO and WHO define risk as a function of the probability of an adverse effect and the magnitude of that effect, consequential to a hazard(s) in food.

Slide 28 Section 2 – sub Module 5.1 - Control of Food Hazards
Control of Food Hazards: Conclusions
Food operators must understand the types of food hazards that are relevant to their production and which risk these hazards pose to the health of consumers.
By understanding which process steps are relevant to food safety a food processor can better control hazards.
Only standardised processes performed by trained personnel who are aware of their responsibilities can be effectively controlled.
Calibrated measuring equipment must be availalbe to control processes.
Monitoring process steps/calibration requires the recording of data.
