The updated Food Safety Preventive Controls Alliance (FSPCA) Preventive Controls for Human Food curriculum provides small and midsized companies a better understanding of how to develop a food safety plan through the use of examples for implementation, with a clear demonstration that the Preventive Controls regulation is a HACCP-based system.

A Hazard Analysis and Critical Control Points (HACCP)-based program is not a document that is simply written and forgotten. Changes occur over time, and a company's food safety and HACCP plans must adapt to reflect these ongoing changes and any new information. This is where reanalysis comes in. Reanalysis is a critical component of the verification principle, where the plan is reviewed to ensure that it is accurate and applicable and that it reflects change and improved understanding.
