Since the publication of the 2004 risk assessment, outbreaks of illness and resultant deaths due to L. monocytogenes continue to occur across the globe. Continued effort is needed to summarize and critically evaluate the most recent information on L. monocytogenes in RTE foods. New data to improve and further inform the 2004 Risk Assessment is available for nearly every factor considered previously, including new quantitative data on L. monocytogenes contamination of foods. To facilitate this work, an FAO/WHO expert meeting was held by virtual means from 20 October to 6 November 2020 to review and discuss the available data and background documents, and to assess the need to modify and update risk assessment models/tools. This report focuses on the deliberations and conclusions of the expert meeting.

Cases of listeriosis appear to be predominantly associated with ready-to-eat products. FAO and WHO have undertaken a risk assessment of Listeria monocytogenes in ready-to-eat foods, prepared and reviewed by an international team of scientists. Input was received from several international fora including expert consultations and Codex Alimentarius committee meetings as well as via public and peer review. This technical report provides complete documentation of the risk assessment, the approaches taken, the data and methodology used, and the results. It also contains four example assessments addressing the risk of listeriosis associated with fresh milk, ice cream, fermented meats and cold-smoked fish. These products were selected to represent typical classes of ready-to-eat products.

In particular, it provides information relevant to risk managers addressing problems posed by this pathogen in ready-to-eat foods. It includes answers to the specific risk management questions posed by the Codex Committee on Food Hygiene and outlines the issues to be considered when implementing control measures, including the establishment of microbiological criteria.

This Brief focuses on Listeria monocytogenes, from isolation methods and characterization (including whole genome sequencing), to manipulation and control. Listeriosis, a foodborne disease caused by Listeria monocytogenes is a major concern for public health authorities. In addition, addressing issues relating to L. monocytogenes is a major economic burden on industry. Awareness of its ubiquitous nature and understanding its physiology and survival are important aspects of its control in the food processing environment and the reduction of the public health concern.

Cases of listeriosis in food appear to be predominantly associated with ready-to-eat products. This publication contains a summary of the risk assessment, jointly undertaken by the Food and Agriculture Organization and the World Health Organization, into the problems posed by the pathogen in ready-to-eat foods. It covers specific risk management questions posed by the Codex Committee on Food Hygiene (CCFH) and outlines issues to be considered when implementing control measures, including the establishment of microbiological criteria. The full technical report is available separately (ISBN 9251051275).

With growing consumer demand for ready-to-eat (RTE) foods that are wholesome and require less handling and preparation, the production of RTE foods has increased and their variety has expanded considerably, spanning from bagged spinach to pre-packaged school lunches. But since RTE foods are normally consumed directly without cooking- a step that ki

Foodborne illnesses continue to be a major public health concern. All members of a particular bacterial genera (e.g., Salmonella, Campylobacter) or species (e.g., Listeria monocytogenes, Cronobacter sakazakii) are often treated by public health and regulatory agencies as being equally pathogenic; however, this is not necessarily true and is an overly conservative approach to ensuring the safety of foods. Even within species, virulence factors vary to the point that some isolates may be highly virulent, whereas others may rarely, if ever, cause disease in humans. Hence, many food safety scientists have concluded that a more appropriate characterization of bacterial isolates for public health purposes could be by virotyping, i.e., typing food-associated bacteria on the basis of their virulence factors. The book is divided into two sections. Section I, “Foodborne Pathogens and Virulence Factors,” hones in on specific virulence factors of foodborne pathogens and the role they play in regulatory requirements, recalls, and foodborne illness. The oft-held paradigm that all pathogenic strains are equally virulent is untrue. Thus, we will examine variability in virulence between strains such as Listeria, Salmonella, Campylobacter, Cronobacter, etc. This section also examines known factors capable of inducing greater virulence in foodborne pathogens. Section II, “Foodborne Pathogens, Host Susceptibility, and Infectious Dose” , covers the ability of a pathogen to invade a human host based on numerous extraneous factors relative to the host and the environment. Some of these factors include host age, immune status, genetic makeup, infectious dose, food composition and probiotics. Readers of this book will come away with a better understanding of foodborne bacterial pathogen virulence factors and pathogenicity, and host factors that predict the severity of disease in humans.

In this book we are concerned with Bayesian learning and forecast ing in dynamic environments. We describe the structure and theory of classes of dynamic models, and their uses in Bayesian forecasting. The principles, models and methods of Bayesian forecasting have been developed extensively during the last twenty years. This devel opment has involved thorough investigation of mathematical and sta tistical aspects of forecasting models and related techniques. With this has come experience with application in a variety of areas in commercial and industrial, scientific and socio-economic fields. In deed much of the technical development has been driven by the needs of forecasting practitioners. As a result, there now exists a relatively complete statistical and mathematical framework, although much of this is either not properly documented or not easily accessible. Our primary goals in writing this book have been to present our view of this approach to modelling and forecasting, and to provide a rea sonably complete text for advanced university students and research workers. The text is primarily intended for advanced undergraduate and postgraduate students in statistics and mathematics. In line with this objective we present thorough discussion of mathematical and statistical features of Bayesian analyses of dynamic models, with illustrations, examples and exercises in each Chapter.

Listeria monocytogenes is an important Gram-positive foodborne pathogen responsible for causing diseases with a high mortality rate in the elderly, pregnant women, neonates, and immunocompromised populations. L. monocytogenes is ubiquitously present in nature and has been isolated from various types of foods. It is especially a challenge in ready-to-eat (RTE) or minimally processed foods that support listerial growth. DNA-based detection and molecular subtyping methods provide important resources for tracking L. monocytogenes contamination throughout the RTE food chain. Combinations of interventions, such as testing and sanitation of food contact surfaces, control of storage temperatures and periods, and use of growth inhibitors in RTE foods that support L. monocytogenes growth are suggested to control L. monocytogenes contamination in the RTE food chain. In addition, a better understanding of the ecology and biology of L. monocytogenes, with a focus on virulence and stress response systems that facilitate transmission through diverse environments encountered by L. monocytogenes, will further facilitate the control of this important foodborne pathogen.

Nanomaterials for Food Applications highlights recent developments in nanotechnologies, covering the different food areas where these novel products or technologies can be applied. The book covers five major themes, showing how nanotechnology is used in food, the use of ingredients in nanoform to improve bioavailability or nanoencapsulation technologies, nanotechnologies for food processing, nanosensors for food quality and safety, nanotechnologies for food packaging, and methods to evaluate potential risks and regulatory issues. This is an important research reference that will be of great value to academic and industrial readers, as topics of importance, both at a research level and for commercial applications, are covered. Regulatory agencies will also be interested in the latest developments covered in the book as they will help set the foundation for further regulations.
