A Food Safety Plan is a key part of a Food Safety Program. The Food Safety Program is the set of procedures a food business has in place to prevent food safety hazards and risks, while the Food Safety Plan is the written document within it that details the potential hazards and the corrective actions to take. For a fuller explanation, see What's the difference between a Food Safety Program and Plan?
In some government documents, the term 'program' may be used. Rest assured that the AIFS HACCP Food Safety Plan Kit meets the legal requirements for creating a plan that implements HACCP.
