Appendix A Current and Proposed Definitions of Key Food Safety Terms One of the important tasks of the committee was to establish the definitions of food safety terms to be used throughout this report. Definitions of key food safety terms from a variety of agencies and organizations were thoroughly reviewed and are listed in Table A.1. To assure uniformity and consistency, the committee decided to adopt most of the definitions published by the International Commission on Microbiological Criteria for Foods (ICMSF, 2002), which are widely accepted throughout the global food safety community. There are a few terms that were specifically defined by the committee, one that was modified from the ICMSF definition, one that was adopted from the Codex Alimentarius Commission, and one that was used in a presentation to the committee (Personal communication, R. Buchanan, Food and Drug Administration, February 5, 2002~. These definitions are explained below. A microbiological criterion defines the acceptability of a product or a food lot, based on the absence or presence or number of microorganisms, including parasites, and/or the quantity of their toxins/metabolites, per unit of mass, vol- ume, area, or lot (CAC, 1997~. Microbiological criteria usually fall into three categories and include microbiological standards, guidelines, and specifications. Microbiological standards are used to determine the acceptability of a food with regard to a regulation or policy. These standards are established by regula- tory authorities and define the microbiological content that foods must meet to be in compliance with a regulation or policy. Foods not meeting the standard are in violation of the regulation or policy and are subject to removal from the market (ICMSF, 2002~. 273

292 APPENDIX A Microbiological guidelines are usually established by a regulatory authority, industry trade association, or a company to indicate the expected microbial content of a food when best practices are applied. Food companies use microbiological guidelines as a basis to design their control systems. These guidelines are advi- sory in nature and may not lead to rejection of a food (ICMSF, 2002~. Microbiological specifications are used by buyers of a food or ingredient to reduce the likelihood of purchasing a product that may be of unacceptable safety or quality. Microbiological specifications can define the microbiological limits for an ingredient so that when it is used, the final product will meet all the requirements for safety and quality. Buyers throughout the food system establish microbiological specifications for materials they purchase. In most cases, specifi- cations are advisory and the materials are sampled periodically. When microbio- logically sensitive ingredients are purchased, each incoming lot may be sampled and tested (ICMSF, 2002~. A performance standard is the degree to which a step or combination of steps in the production, processing, distribution, and/or preparation of a food must operate to achieve the desired level of control over a hazard (Personal communi- cation, R. Buchanan, Food and Drug Administration, February 5, 2002~. The term performance standard does not appear anywhere in the U.S. Department of Agriculture Pathogen Reduction/Hazard Analysis and Critical Control Point Final Rule (USDA, 1996), but was incorporated from regulations used in other industries. It should be noted that the committee defined a food safety objective as a statement of the maximum frequency and/or hazard in a food at the time of consumption that is considered tolerable for consumer protection. This is broader and less restrictive than the ICMSF definition of the term because it includes microbiological, chemical, and physical hazards. It should also be noted that the committee changed the word "acceptable" to "tolerable" because contamination of food is seldom acceptable; it cannot be deemed "appropriate" either. A public health objective is a measurable population-based target for main- taining or improving health, while a public health goal is the desired outcome associated with reducing the burden of disease in society. The committee defined the term zero tolerance as the lay audience percep- tion of the absence of a hazard that cannot be scientifically assured but is opera- tionally defined as the absence of a hazard in a specified amount of food as determined by a specific method.

Food safety regulators face a daunting task: crafting food safety performance standards and systems that continue in the tradition of using the best available science to protect the health of the American public, while working within an increasingly antiquated and fragmented regulatory framework. Current food safety standards have been set over a period of years and under diverse circumstances, based on a host of scientific, legal, and practical constraints.

Scientific Criteria to Ensure Safe Food lays the groundwork for creating new regulations that are consistent, reliable, and ensure the best protection for the health of American consumers. This book addresses the biggest concerns in food safety—including microbial disease surveillance plans, tools for establishing food safety criteria, and issues specific to meat, dairy, poultry, seafood, and produce. It provides a candid analysis of the problems with the current system, and outlines the major components of the task at hand: creating workable, streamlined food safety standards and practices.
