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.

During foodborne illness outbreak investigations, public health and regulatory authorities collect three types of data to determine a common food consumed by ill people: epidemiologic, traceback, and laboratory. State and local partners work with FDA to conduct traceback investigations and examine the food supply chain to determine the origin of the foods identified by the epidemiologic investigations. This article looks at the benefits of using incident command system (ICS) principles during emergency response coordination activities for foodborne illness outbreaks, with input from members of the FDA's CORE Network.

This article covers U.S. regulatory oversight in establishing pesticide residue tolerances, testing for residues in domestic goods and imports, and the importance of science-based standards for global trade and food safety.

Many of the techniques used in creating a HACCP plan are shared with other types of plans, such as food quality and food defense plans. This article discusses regulatory changes in the dairy industry through the years, including the Grade "A" Pasteurized Milk Ordinance (PMO), the National Conference on Interstate Milk Shippers Dairy HACCP Pilot Program, and the incorporation of the Food Safety Modernization Act Preventive Controls Rule within the PMO.
