Whole genome sequencing as a tool to strengthen foodborne disease surveillance and response. Module 3


Book Description

Globally, there is growing recognition of foodborne diseases as a public health priority. From a public health perspective, foodborne diseases are largely preventable, and can be controlled through effective food safety systems that evaluate hazards along the food chain, from production to consumption. An integrated food chain surveillance system can detect and monitor foodborne bacteria, including antimicrobial resistant bacteria, throughout the food chain. Whole genome sequencing (WGS) has the potential to change how we detect and monitor microbial hazards in the food chain, as well as how we assess, investigate and manage food safety risks. It is anticipated that this new technology will help reduce the burden of foodborne diseases, given its advantages over previous low-resolution typing and detection methods. The purpose of this manual is to provide guidance on: - The capacities that need to be in place before WGS can be useful for foodborne disease surveillance and response; - The options for implementing WGS; and - How to implement WGS within existing surveillance and response systems. This module is about using WGS in routine surveillance of foodborne diseases. It is meant for countries experienced in laboratory-based surveillance of foodborne pathogens. WGS can be implemented where subtyping foodborne pathogens or replacing traditional typing methods is being considered. Routine surveillance includes outbreak detection, monitoring trends over time, and using WGS for AMR and virulence factor monitoring.

Food Microbiology


Book Description

Looking for a comprehensive textbook that covers the interaction between micro-organisms and food? Spoilage, foodborne illness, and fermentation. Food Microbiology has been the most popular textbook in this area since it was first published in 1995. Now in its fifth edition, the highly successful authors bring the book right up to date. Maintaining its general structure and philosophy to encompass modern food microbiology, this new edition provides updated and revised individual chapters and uses new examples to illustrate incidents. It covers the three main aspects of the interaction between micro-organisms and food and the positive and negative features that result. Attention is paid to the illustrations included and there is a discussion on the factors affecting the presence of micro-organisms in foods and their capacity to survive and grow. Finally, recent developments in procedures used to assay and control the microbiological quality of food and protect public health are reported. Thorough and accessible, this book is designed for students in the biological sciences, biotechnology, and food science, as well as a valuable resource for researchers, teachers, and practising food microbiologists.







WHO global strategy for food safety 2022-2030


Book Description

The new WHO Global Strategy for Food Safety 2022-2030 was adopted by the Seventy-fifth World Health Assembly in 2022. The updated strategy addresses current and emerging challenges, incorporates new technologies and includes innovative approaches for strengthening food safety systems. The target audience includes policy-makers (national and subnational governments), technical authorities/agencies responsible for food safety, academia, food business operators (FBOs) and private sectors, consumers, civil societies, UN agencies and WHO staff. This new document was prepared with support from the Technical Advisory Group (TAG) on Food Safety: Safer food for better health. It reflects feedback received through consultation process with Member States and governmental institutions, United Nations agencies and other intergovernmental organizations, academia, NGOs, private sector entities, and individuals working in public health and food safety. The vision of the draft strategy is to ensure that all people, everywhere, consume safe and healthy food to reduce the burden of foodborne diseases. With five interlinked and mutually supportive strategic priorities, the draft strategy aims to build forward-looking, evidence-based, people-centred, and cost-effective food safety systems with coordinated governance and adequate infrastructures. This strategy contributes to the achievement of the SDGs and will be reviewed in 2030 when the world will reflect upon the progress made towards the SDGs.

Management of Legionella in Water Systems


Book Description

Legionnaires' disease, a pneumonia caused by the Legionella bacterium, is the leading cause of reported waterborne disease outbreaks in the United States. Legionella occur naturally in water from many different environmental sources, but grow rapidly in the warm, stagnant conditions that can be found in engineered water systems such as cooling towers, building plumbing, and hot tubs. Humans are primarily exposed to Legionella through inhalation of contaminated aerosols into the respiratory system. Legionnaires' disease can be fatal, with between 3 and 33 percent of Legionella infections leading to death, and studies show the incidence of Legionnaires' disease in the United States increased five-fold from 2000 to 2017. Management of Legionella in Water Systems reviews the state of science on Legionella contamination of water systems, specifically the ecology and diagnosis. This report explores the process of transmission via water systems, quantification, prevention and control, and policy and training issues that affect the incidence of Legionnaires' disease. It also analyzes existing knowledge gaps and recommends research priorities moving forward.




Framework for a Public Health Emergency Operations Centre


Book Description

The Framework for a Public Health Emergency Operations Centre (PHEOC framework) document is intended to be used by practitioners of public health; health policy makers; and authorities and agencies responsible for managing emergencies, incidents, or events where the health of populations is at risk. This document provides high-level methodical guidance for designing, developing, and strengthening of public health emergency operations centers. This interim document outlines the key concepts and essential requirements for developing and managing a public health EOC (PHEOC). The overall approach is generic and based on widely acknowledged elements of all-hazards emergency management. It provides an outline for developing and managing a PHEOC to achieve a goal-oriented response to public health emergencies and unity of effort among response agencies. The document will be revised as necessary. Practical guidance on specific aspects of the PHEOC framework will be developed and published separately. A public health emergency is here defined as an occurrence, or imminent threat, of an illness or health condition that poses a substantial risk of a significant number of human fatalities, injuries or permanent or long-term disability. Public health emergencies can result from a wide range of hazards and complex emergencies. Experience has shown that timely implementation of an EOC provides an essential platform for the effective management of public health emergencies. Public health emergencies involve increased incidence of illness, injury and/or death and require special measures to address increased morbidity, mortality and interruption of essential health services. For such emergencies, a multi-agency, multi-jurisdictional response is often required, working with the national disaster management organization. When normal resources and capacities are exceeded, support from outside the affected areas will also be required. External assistance could include national, cross-border, regional or international resources.
