Foodborne Pathogens Hygiene And Safety

Globalization of the food supply has created conditions favorable for the emergence, reemergence, and spread of food-borne pathogens-compounding the challenge of anticipating, detecting, and effectively responding to food-borne threats to health. In the United States, food-borne agents affect 1 out of 6 individuals and cause approximately 48 million illnesses, 128,000 hospitalizations, and 3,000 deaths each year. This figure likely represents just the tip of the iceberg, because it fails to account for the broad array of food-borne illnesses or for their wide-ranging repercussions for consumers, government, and the food industry-both domestically and internationally. A One Health approach to food safety may hold the promise of harnessing and integrating the expertise and resources from across the spectrum of multiple health domains including the human and veterinary medical and plant pathology communities with those of the wildlife and aquatic health and ecology communities. The IOM's Forum on Microbial Threats hosted a public workshop on December 13 and 14, 2011 that examined issues critical to the protection of the nation's food supply. The workshop explored existing knowledge and unanswered questions on the nature and extent of food-borne threats to health. Participants discussed the globalization of the U.S. food supply and the burden of illness associated with foodborne threats to health; considered the spectrum of food-borne threats as well as illustrative case studies; reviewed existing research, policies, and practices to prevent and mitigate foodborne threats; and, identified opportunities to reduce future threats to the nation's food supply through the use of a "One Health" approach to food safety. Improving Food Safety Through a One Health Approach: Workshop Summary covers the events of the workshop and explains the recommendations for future related workshops.

Foodborne pathogens continue to cause major public health problems worldwide and have escalated to unprecedented levels in recent years. In this book, major foodborne diseases and the key food safety issues are discussed elaborately. In addition, emerging and reemerging microbial agents and other food safety related topics are discussed. This book

The Bad Bug was created from the materials assembled at the FDA website of the same name. This handbook provides basic facts regarding foodborne pathogenic microorganisms and natural toxins. It brings together in one place information from the Food & Drug Administration, the Centers for Disease Control & Prevention, the USDA Food Safety Inspection Service, and the National Institutes of Health.

Developments such as the increasing globalization of the food industry, constant innovations in technologies and products, and changes in the susceptibility of populations to disease have all highlighted the problem of emerging pathogens, either newly discovered through more sensitive analytical methods, linked for the first time to disease in humans, or newly associated with a particular food. Designed for microbiologists and quality assurance professionals and for government and academic food safety scientists, this timely reference discusses ways of identifying emerging pathogens and includes chapters on individual pathogens, their epidemiology, methods of detection, and means of control.

Written from a “farm-to-fork” perspective, Food Safety: Theory and Practice provides a comprehensive overview of food safety and discusses the biological, chemical, and physical agents of foodborne diseases. Early chapters introduce students to the history and fundamental principles of food safety. Later chapters provide an overview of the risk and hazard analysis of different foods and the important advances in technology that have become indispensable in controlling hazards in the modern food industry. The text covers critically important topics and organizes them in a manner to facilitate learning for those who are, or who may become, food safety professionals. Topics Covered • Risk and hazard analysis of goods • The prevention of foodborne illnesses and diseases • Safety management of the food supply • Food safety laws, regulations, enforcement, and responsibilities • The pivotal role of food sanitation/safety inspectors Instructor Resources PowerPoint Presentations, Test Bank, and an Instructor’s Manual, are available as free downloads.

A question raised by many individuals today – “How Safe is Our Food Consumed Today?” Food safety has become a hot topic and an important public issue due to the increasingly widespread nature of foodborne illnesses in both developed and developing countries. As food is biological in nature and supplies consumers with nutrients, it is also equally capable of supporting the growth of microorganisms from the environmental sources. A precise method of monitoring and detecting of foodborne pathogens including Salmonella sp., Vibrio sp., Listeria monocytogenes, Campylobacter and Norovirus is needed to prevent and control human foodborne infections. Clinical treatments of infection caused by foodborne pathogens are becoming tougher with the increase number of multidrug resistant pathogens in the environment. This situation creates a huge healthcare burden – e.g. prolonged treatment for infections, decrease in the efficacy of antibiotic, delay in treatment due to unavailability of new antibiotics, and increased number of deaths. As such, continuous investigation of the foodborne pathogens is needed to pave the way for a deeper understanding on the foodborne diseases and to improve disease prevention, management and treatments.

Low water activity (aw) and dried foods such as dried dairy and meat products, grain-based and dried ready-to-eat cereal products, powdered infant formula, peanut and nut pastes, as well as flours and meals have increasingly been associated with product recalls and foodborne outbreaks due to contamination by pathogens such as Salmonella spp. and enterohemorrhagic E. coli. In particular, recent foodborne outbreaks and product recalls related to Salmonella-contaminated spices have raised the level of public health concern for spices as agents of foodborne illnesses. Presently, most spices are grown outside the U.S., mainly in 8 countries: India, Indonesia, China, Brazil, Peru, Madagascar, Mexico and Vietnam. Many of these countries are under-developed and spices are harvested and stored with little heed to sanitation. The FDA has regulatory oversight of spices in the United States; however, the agency’s control is largely limited to enforcing regulatory compliance through sampling and testing only after imported foodstuffs have crossed the U.S. border. Unfortunately, statistical sampling plans are inefficient tools for ensuring total food safety. As a result, the development and use of decontamination treatments is key. This book provides an understanding of the microbial challenges to the safety of low aw foods, and a historic backdrop to the paradigm shift now highlighting low aw foods as vehicles for foodborne pathogens. Up-to-date facts and figures of foodborne illness outbreaks and product recalls are included. Special attention is given to the uncanny ability of Salmonella to persist under dry conditions in food processing plants and foods. A section is dedicated specifically to processing plant investigations, providing practical approaches to determining sources of persistent bacterial strains in the industrial food processing environment. Readers are guided through dry cleaning, wet cleaning and alternatives to processing plant hygiene and sanitation. Separate chapters are devoted to low aw food commodities of interest including spices, dried dairy-based products, low aw meat products, dried ready-to-eat cereal products, powdered infant formula, nuts and nut pastes, flours and meals, chocolate and confectionary, dried teas and herbs, and pet foods. The book provides regulatory testing guidelines and recommendations as well as guidance through methodological and sampling challenges to testing spices and low aw foods for the presence of foodborne pathogens. Chapters also address decontamination processes for low aw foods, including heat, steam, irradiation, microwave, and alternative energy-based treatments.
