The HACCP Plan is not a stand alone program, but rather part of a larger food safety system. The foundational programs that are part of the food safety system are frequently termed prerequisite programs. The term was coined to indicate that they should be in place before HACCP based systems are implemented in order to effectively manage risk from foodborne hazards. The Current Good Manufacturing Practice (GMP) regulations address requirements for many prerequisite programs. USDA section 402(a)(3) outlines the conditions and practices the regulated food industry must follow for processing safe food under sanitary conditions, including personnel, plant and grounds, sanitary operations, sanitary facilities and controls, equipment and utensils, processes and controls, warehousing and distribution, and defect action levels considerations. Elements of GMPs that are not covered in the HACCP are still required by regulations.
