Synopsis (short abstract) During the past ten years, considerable advancements have been achieved in the development of quantitative risk assessments for microbial pathogens in the food supply. More recently, new risk-based management concepts and approaches have been introduced, including the application of food safety objectives (FSOs), performance objectives (POs), and performance criteria (PCs) in order to relate public health goals to the level of stringency required for food safety measures and systems. From these parameters, food safety controls such as process criteria, product criteria and microbiological criteria may be derived. Risk assessments provide the basis for risk-based management options, however, guidelines, methods and practical examples of using risk assessment outputs toward these goals are lacking.

Shiga toxin-producing Escherichia coli (STEC) and food: attribution, characterization, and monitoring
Meeting Report

Shiga toxin-producing Escherichia coli (STEC) infections are a substantial health issue worldwide. Circa 2010, foodborne STEC caused > 1 million human illnesses, 128 deaths, and ~ 13,000 Disability Adjusted Life Years (DALYs). Targeting interventions appropriately relies on identifying those strains of greatest risk to human health and determining the types of foods that cause STEC infections. There are hundreds of STEC serotypes; however, based on the evidence gathered during the review, the Expert Group concluded that the serotype of the STEC strain should not be considered a virulence criterion. All STEC strains with the same serotype should not be assumed to carry the same virulence genes and to pose the same risk, as many STEC virulence genes are mobile and can be lost or transferred to other bacteria. this report proposes a set of criteria for categorizing the potential risk of severity of illness associated with a STEC in food is recommended based on evidence of virulence gene profiles and associations with clinical severity. The criteria could be applied by risk managers in a risk-based management approach to control STEC in food. While ruminants and, other land animals are considered the main reservoirs for STEC, various largescale outbreaks have been linked to other foods. Thus, the report also addresses source attribution of foodborne STEC infections globally in order to inform the development of international standards by the Codex Alimentarius on the control of STEC, and in particular identify the foods which should be the focus of those standards. Finally it provides a review of monitoring programmes and methodology for STEC which can serve as a reference for countries planning to develop such programmes.

The specific objectives of the meeting were to: • Review the existing risk assessments on EHEC in terms of (a) their fulfilling their scope and providing the basis for scientifically-based risk-management actions; and (b) their potential application (in whole or on a modular basis) to the development of a risk assessment at the international level. • Consider the risk management actions, if any, taken to date that were based on risk assessment and identify the strengths and weakness of the risk assessments from a risk management perspective, in particular identifying when and why the risk assessments did not meet the needs of risk managers. • Identify the key issues currently faced by risk managers in terms of addressing the problems associated with EHEC in raw beef and beef products. Considering the output of the above objectives and the existing data on EHEC in raw beef and beef products, provide guidance to FAO and WHO on the specific areas to be addressed in any future work on this issue, and how to address them.

Case study: Vibrio vulnificus in oysters

The Codex Committee on Food Hygiene (CCFH) has requested that the Food and Agriculture Organization of the united Nations and the World Health Organization (FAO/WHO) provide scientific advice on how Performance Objectives (PO) and Performance Criteria (PC) can be utilized to achieve Food Safety Objectives (FSO). The ultimate goal is to produce a reference document that will assist CCFH and countries in using risk assessment to develop risk management measures. This Working Group was assigned th e task of interpreting data and information on Vibrio vulnificus illness associated with the consumption of oysters, including the FAO/WHO Risk Assessment of Vibrio vulnificus in Raw Oysters (FAO/WHO, 2005), and transforming it into practical guidance that can be used by risk managers to elaborate potential risk management options. Such guidance involves knowledge of the dynamics of pathogen growth, survival and inactivation in order to establish scientifically defensible POs and PCs at specific points within the food chain, as well as to identify potential microbiological, process and product criteria.
