How does industry validate elements of HACCP plans?

Validation is defined as the element of verification focused on collecting and evaluating scientific and technical information to determine whether the HACCP plan, when properly implemented, will effectively control the hazards. The primary focus of validation for industry is to determine that critical limits at critical control points are capable of controlling the identified hazards; however, other elements such as monitoring can also be validated. Validation may involve the use of scientific publications, historical knowledge, regulatory documents, experimental trials, and other approaches. This paper reviews how the industry in the United States has validated elements of HACCP plans.
