Once implemented, it is important to maintain a HACCP plan properly. Verification of the plan will help to determine if employees are properly monitoring a CCP (see Chapter 6). A HACCP plan should also be regularly reassessed, particularly as changes are made in processing methods and in intended users of the final product (again, see Chapter 6).
These verification activities should be maintained as continuous additions to the HACCP plan. They should also go through the same review and approval process as the original plan.
It is very important that operations keep up-to-date with their record keeping (monitoring, corrective actions, etc.), as even the best-intentioned operation will be in trouble if it gets behind in its records.
