Important considerations when using the decision tree:The decision tree is used after the hazard analysis.
The decision tree is used at the steps where a "significant hazard" has been identified. These are hazards that may reasonably be expected to occur. Non-significant hazards (i.e., of low risk and unlikely to occur) have been excluded.
A process which does not have a significant hazard does not need a HACCP plan.
Each step which is a CCP must agree with the definition: a point, step, or procedure at which control can be applied and a food safety hazard can be prevented, eliminated, or reduced to acceptable levels.
A subsequent step in the process under your control may be more effective for controlling a hazard and may be the preferred CCP.
More than one step in a process may be involved in controlling a hazard.
More than one hazard may be controlled by a specific preventative measure.
