Description: 

“The application of methods, procedures, test and other evaluations, in addition to monitoring, to determine whether a control measure or combination of control measures is or has been operating as intended and to establish the validity of the food safety plan.” – 21 CFR 117.3


Verification provides evidence to demonstrate that the Food Safety Plan is working and being implemented as written. Several types of verification activities may be necessary for each preventive control to ensure that the procedures used are effective.


Ongoing verification actives such as calibration of monitoring instruments to ensure their accuracy and periodic in‐process or end-product testing to verify process control are important in showing that the Food Safety Plan works. Sanitation Preventive Controls, environmental monitoring is a verification activity to demonstrate that sanitation preventive controls are effective in facilities that produce ready‐to‐eat food that is exposed to the environment.


Supervisory review of monitoring, corrective action and verification (e.g., calibration and product testing) records is another type of verification that is used to demonstrate that the Food Safety Plan is being implemented as intended.


Verification Record Review:

All monitoring and corrective action records should be reviewed under the oversight of a preventive controls qualified individual. This review is a verification activity. These records are valuable tools that document that the Food Safety Plan is operating within established safety parameters and that deviations are handled appropriately. However, records alone are meaningless unless someone reviews them on a periodic basis to “verify” that critical limits were met and the Food Safety Plan is being followed. Regulations require that monitoring and corrective action records be reviewed within seven (7) working days under the oversight of a preventive controls qualified individual. Preferably the records are reviewed prior to release of product to prevent potential recall and unintended consequences should a deviation be discovered during record review. Corrective action must be taken if the record review determines that a deviation has occurred. This may hold true for sanitation preventive controls records if, for example, the product is no longer in the establishment’s control and the lack of proper implementation of the preventive control may lead to a hazard being likely to occur in the product.


The value of record review is maximized when the data are analyzed to look for trends. For example, are the verification results for one supplier the same as another supplier, or are there differences that warrant investigation? Are Listeria indicators isolated with greater frequency in one location? Do sanitation verification results indicate higher counts on one line or in one area? If a trend emerges during record review, adjustments may be warranted to minimize the potential for a future deviation. A rigorous verification program can be the basis for continuous improvement of operations and lead to a more effective food safety system.
