Principle 1.3: Specify the control measures for each hazard

What does this mean?

Control measures are actions and/or activities that are taken to prevent, eliminate or reduce the occurrence of a hazard that you have identified.

How is this stage achieved?

Only significant hazards (i.e. those above your predetermined significance score trigger point) will be carried forward to this stage.

For each significant hazard record what actions and/or activities are to be taken to prevent, eliminate or reduce the hazard to an acceptable level.

Control measures are often confused with monitoring.  Monitoring is carried out to check that the control measure put in place to control the hazard is working. Here are the definitions of “control measure” and “monitoring” to help you understand the difference:

Control Measure:    Any action and/or activity that can be used to prevent or eliminate a food safety hazard or reduce it to an acceptable level.

Monitoring:    Conducting planned observations or measurements to assess whether a CCP is under control.

  • More than one control measure may be necessary to effectively manage a specific hazard, see Process Step 15 in Table 1.

  • One control measure may manage more than one hazard.  For instance in Process Step 10 in Table 1 scheduled oil temperature and fry time can be an effective control for reducing both numbers of Salmonella and Campylobacter.

  • Control measures are not always carried out at the same Process Step where the hazard arises.  For example a hazard at Process Step 1 may be ‘presence of metal in raw material from supplier’ this may have several controls including the use of only pre-approved suppliers, or supply to an agreed specification.  These controls will appear at Process Step 1 however a control measure at Process Step 15 ‘effective working metal detector and rejection system’ is also a control for this hazard.

10

Deep Fry

Survival of bacteria due to undercooking: low oil temperature or short exposure time.

Stated oil temperature and fry time

Checks on the continual measurement of oil temperature to be taken on the first product at the start of the shift, every 30 minutes thereafter and on the last product of the shift

Timer with alarm to be activated as each batch is placed in the fryer

15

Metal detection

Introduction of metal from broken machinery

Effective working metal detector and rejection system

Metal detector checks taken at the start of a run, end of a run and every 20 minutes.  The checks are carried out using 1.5mm Ferrous, 2.0mm Non-Ferrous and 3.0mm Stainless Steel, all are to be detected and rejected by the metal detector.
