There are several decision tress that can be used to help show the difference between a
CCP and a CP. A
CCP is critical - absolutely necessary to control (reduce or eliminate) a reasonable likely food safety hazard in the process. For example - cooking poultrhy - the cook step is a
CCP to destroy Salmonella. The hazard is likley, the control step is necessary.
A CP is a control step which may be important and good - but not crucial - either because the risk is low or because a mistake is not likley. For example, you might check to be sure employees are washing their hands throughout the day in the processing environment. This helps control, but is not necessarily a critical factor because it might be known that this is routinely under control and not a likley factor contributing to risk.
