Any time a new piece of equipment, such as an increasingly relevant “collaborative robot” (cobot), is incorporated, the food safety plan—including the hazard analysis—must be reanalyzed to determine the new equipment’s impact on the food safety system, and what mitigation strategies must be deployed.

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.
