Control of Salmonella and Other Bacterial Pathogens in Low-Moisture Foods by Richard Podolak,Darryl G. Black Pdf

The first and only comprehensive reference/solutions manual for managing food safety in low-moisture foods The first book devoted to an increasingly critical public health issue, Control of Salmonella and Other Bacterial Pathogens in Low-Moisture Foods reviews the current state of the science on the prevalence and persistence of bacterial pathogens in low-moisture foods and describes proven techniques for preventing food contamination for manufacturers who produce those foods. Many pathogens, such as Salmonella, due to their enhanced thermal resistance in dry environments, can survive the drying process and may persist for prolonged periods in low-moisture foods, especially when stored in refrigerated environments. Bacterial contamination of low-moisture foods, such as peanut butter, present a vexing challenge to food safety, and especially now, in the wake of widely publicized food safety related events, food processors urgently need up-to-date, practical information on proven measures for containing the risk of contamination. While much has been written on the subject, until now it was scattered throughout the world literature in scientific and industry journals. The need for a comprehensive treatment of the subject has never been greater, and now this book satisfies that need. Discusses a wide variety of foods and evaluates multiple processing platforms from the standpoint of process validation of all food safety objectives for finished food products Takes a practical approach integrating the latest scientific and technological advances in a handy working resource Presents all known sources and risk factors for pathogenic bacteria of concern in the manufacturing environment for low-moisture/water activity products Characterizes the persistence and thermal resistance of bacterial pathogens in both the environment and most low-moisture food products Control of Salmonella and Other Bacterial Pathogens in Low-Moisture Foods is a much-needed resource for food microbiologists and food industry scientists, as well as managers and executives in companies that produce and use low-moisture foods. It also belongs on the reference shelves of food safety regulatory agencies worldwide.

The Microbiological Safety of Low Water Activity Foods and Spices by Joshua B. Gurtler,Michael P. Doyle,Jeffrey L. Kornacki Pdf

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.

Emerging foodborne pathogens by Yasmine Motarjemi,Martin Adams Pdf

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.

Listeria by Chris Bell,Alex Kyriakides Pdf

The independent investigations some 70 years ago by E. G. D. Murray and colleagues in Cambridge (UK) and J,H. H. Pirie in Johannesburg (South Mrica) resulted in the first detailed descriptions of listeriosis (in both instances in small animals), together with the isolation and naming of Lis teria monocytogenes. These descriptions in 1926 and 1927 show the pre cision and care of these experimentalists, for not only did they show much skill and attention to detail but also great insight in surmising that the consumption of contaminated food was associated with the trans mission of listeriosis. In the words of Pirie in 1927, 'Infection can be pro duced by subcutaneous inoculation or by feeding and it is thought that it is by feeding that the disease is spread in nature. ' These observations were largely forgotten and listeriosis was regarded as a rather obscure disease of animals and occasionally humans. However, the 1980s saw dramatic changes and the 'elevation' of Listeria to a topic of concern not only amongst microbiologists (particularly food micro biologists) but also the general public.

Microbiological safety of lipid-based ready-to-use foods for management of moderate acute malnutrition and severe acute malnutrition by Food and Agriculture Organization of the United Nations,World Health Organization Pdf

Consistent with the need to provide safe food for young children, particularly during the complementary feeding period between 6 and 24 months and the period of rapid development to age 59 months, FAO and WHO convened a technical meeting in FAO headquarters, Rome, Italy, from 11 to 14 December 2012 that addressed the microbial safety of ready-to-use foods (RUF) for the management of acute malnutrition. The meeting was held at the request of the WFP and UNICEF to help them formulate a science-based response to the finding of Cronobacter spp. in lipid-based RUF and to provide guidance on appropriate microbiological specifications to include among other purchase requirements to enhance the safety of lipid-based RUF. This report provides an overview of the assessment of the risk posed by Cronobacter spp in this product and provides guidance to agencies distributing the product as well of the producers on how to manage this problem and minimise the risk to the vulnerable consuming popula tion.

Foodborne Pathogens by Joshua B. Gurtler,Michael P. Doyle,Jeffrey L. Kornacki Pdf

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.

Food Spoilage Microorganisms by Clive de W Blackburn Pdf

The control of microbiological spoilage requires an understanding of a number of factors including the knowledge of possible hazards, their likely occurrence in different products, their physiological properties and the availability and effectiveness of different preventative measures. Food spoilage microorganisms focuses on the control of microbial spoilage and provides an understanding necessary to do this. The first part of this essential new book looks at tools, techniques and methods for the detection and analysis of microbial food spoilage with chapters focussing on analytical methods, predictive modelling and stability and shelf life assessment. The second part tackles the management of microbial food spoilage with particular reference to some of the major food groups where the types of spoilage, the causative microorganisms and methods for control are considered by product type. The following three parts are then dedicated to yeasts, moulds and bacteria in turn, and look in more detail at the major organisms of significance for food spoilage. In each chapter the taxonomy, spoilage characteristics, growth, survival and death characteristics, methods for detection and control options are discussed. Food spoilage microorganisms takes an applied approach to the subject and is an indispensable guide both for the microbiologist and the non-specialist, particularly those whose role involves microbial quality in food processing operations. Looks at tools, techniques and methods for the detection and analysis of microbial food spoilage Discusses the management control of microbial food spoilage Looks in detail at yeasts, moulds and bacteria
