Microorganisms in Foods 8: Use of Data for Assessing Process Control and Product Acceptance is written by the International Commission on Microbiological Specifications for Foods with assistance from a limited number of consultants. The purpose of this book is to provide guidance on appropriate testing of food processing environments, processing lines, and finished product to enhance the safety and microbiological quality of the food supply. Microorganisms in Foods 8 consists of two parts. Part I, Principles of Using Data in Microbial Control, builds on the principles of Microorganisms in Foods 7: Microbiological Testing in Food Safety Management (2002), which illustrates how HACCP and Good Hygienic Practices (GHP) provide greater assurance of safety than microbiological testing, but also identifies circumstances where microbiological testing may play a useful role. Part II, Specific Applications to Commodities, provides practical examples of criteria and other tests and is an updated and expanded version of Part II of Microorganisms in Foods 2: Sampling for Microbiological Analysis: Principles and Specific Applications (2nd ed. 1986). Part II also builds on the 2nd edition of Microorganisms in Foods 6: Microbial Ecology of Food Commodities (2005) by identifying appropriate tests to evaluation the effectiveness of controls.

Principles of Microbiological Troubleshooting in the Industrial Food Processing Environment provides proven approaches and suggestions for finding sources of microbiological contamination of industrially produced products. Industrial food safety professionals find themselves responsible for locating and eliminating the source(s) of food contamination. These are often complex situations for which they have not been adequately prepared. This book is written with them, the in-plant food safety/quality assurance professional, in mind. However, other professionals will also benefit including plant managers, regulatory field investigators, technical food safety policy makers, college instructors, and students of food science and microbiology. A survey of the personal and societal costs of microbial contamination of food is followed by a wide range of respected authors who describe selected bacterial pathogens, emerging pathogens, spoilage organisms and their significance to the industry and consumer. Dr. Kornacki then provides real life examples of in-plant risk areas / practices (depicted with photographs taken from a wide variety of food processing facilities). Factors influencing microbial growth, survival and death area also described. The reader will find herein a practical framework for troubleshooting and for assessing the potential for product contamination in their own facilities, as well as suggestions for conducting their own in-plant investigations. Selected tools for testing the environment and statistical approaches to testing ingredients and finished product are also described. The book provides suggestions for starting up after a processing line (or lines) have been shut down due to a contamination risk. The authors conclude with an overview of molecular subtyping and its value with regard to in-plant investigations. Numerous nationally recognized authors in the field have contributed to the book. The editor, Dr. Jeffery L. Kornacki, is President and Senior Technical Director of the consulting firm, Kornacki Microbiology Solutions in Madison, Wisconsin. He is also Adjunct Faculty with the Department of Food Science at the University of Georgia and also with the National Food Safety & Toxicology Center at Michigan State University.

The second edition of Microorganisms in Foods 7: Microbiological Testing in Food Safety Management updates and expands on information on the role of microbiological testing in modern food safety management systems. After helping the reader understand the often confusing statistical concepts underlying microbiological sampling, the second edition explores how risk assessment and risk management can be used to establish goals such as a “tolerable levels of risk,” Appropriate Levels of Protection, Food Safety Objectives or Performance Objectives for use in controlling foodborne illness. Guidelines for establishing effective management systems for control of specific hazards in foods are also addressed, including new examples for pathogens and indicator organisms in powdered infant formula, Listeria monocytogenes in deli-meats, enterohemorrhagic Escherichia coli in leafy green vegetables, viruses in oysters and Campylobacter in poultry. In addition, a new chapter on application of sampling concept to microbiological methods, expanded chapters covering statistical process control, investigational sampling, environmental sampling, and alternative sampling schemes. The respective roles of industry and government are also explored, recognizing that it is through their collective actions that effective food safety systems are developed and verified. Understanding these systems and concepts can help countries determine whether imported foods were produced with an equivalent level of protection. Microorganisms in Foods 7 is intended for anyone using microbiological testing or setting microbiological criteria, whether for governmental food inspection and control, or industrial applications. It is also intended for those identifying the most effective use of microbiological testing in the food supply chain. For students in food science and technology, this book provides a wealth of information on food safety management principles used by government and industry, with many references for further study. The information was prepared by the International Commission on Microbiological Specifications for Foods (ICMSF). The ICMSF was formed in response to the need for internationally acceptable and authoritative decisions on microbiological limits for foods in international commerce. The current membership consists of fifteen food microbiologists from twelve countries, drawn from government, universities, and food processing and related industries.

Microbiological Quality of Foods contains the proceedings of a conference held in Franconia, New Hampshire, on August 27-29, 1962. Contributors review the state of knowledge of foodborne diseases and discuss the use and efficiency of microbiological tests and standards for food quality from the academic, regulatory, and industrial standpoints. Problems related to the use of microorganisms as an index of food quality are given special attention. This book includes a consideration of total counts, coliforms, fecal streptococci, and the detection of specific pathogens. This text is organized into 26 chapters and begins with an overview of the status of microbiological tests and standards that have been developed to ensure food quality. The book then discusses the concerns of regulators at the federal and local levels concerning food microbiology, particularly the safety or wholesomeness of foods. The next chapters focus on industry perspectives regarding food safety; the role of universities in food microbiological research; and problems and challenges presented by foodborne diseases. The book also introduces the reader to staphylococcal enterotoxins, halophilic bacteria, botulism, and Clostridium perfringens that causes food poisoning. This book is a valuable resource for those involved in food microbiology, science and technology, and industry; bacteriology; and public health.

Food plays an essential part in everyday life. Food should be tasty, healthy, sustainable and preferably not too expensive. But food should also be safe and with sufficient guarantees on maintaining good quality aspects until the end of shelf life. The various actors in the food supply chain have an interest in verifying the expected quality and safety by means of microbiological analyses of food. Measurement brings knowledge and microbiological guidelines help in the decision-making process for judging the acceptability of food or food production processes. The present handbook provides microbiological guidelines and current applicable EU legal criteria (status 1.1.2018) for a wide range of food categories (dairy, meat, seafoods, plant-based foods, bakery products, composite foods, shelf-stable food, water) and subcategories therein, based upon the type of food processing and intrinsic characteristics of the foods. This book can be consulted to provide quick answers on the expected microbiological contamination of foodstuff. It can help in interpretation of test results in assessing good (hygienic) practices in the production of food, determining the shelf life and ensuring food safety. The handbook also presents definitions of the wide variety of foodstuffs available and some reflections on, in particular, food safety issues or the on-going debate for some food items in assessing microbial quality. This book provides crucial information about food safety, for the use of students and professionals. EXTRACT "First we eat, then we do everything else" M.F.K. Fisher Food plays an important part in everyday life. But when being a food scientist or in the food business, food gets to be an even bigger part of your life. Our team at the Food Microbiology and Food Preservation research group (FMFP-UGent) at Ghent University during its academic tasks in education, research, scientific activities at committees, but also in interaction with many food companies and stakeholders in the food supply chain in projects or contract work, has built up considerable expertise on the microbiological analysis of a large variety of foodstuffs. Being situated in Ghent, and thus close to Brussels, the heart of Europe, we intrinsically have to understand and deal with legal EU criteria or action limits. The latter is the reason why this book is mainly oriented towards inclusion or making reference to EU legal microbiological criteria for foodstuffs as well. ABOUT THE AUTHORS The main author, Prof. Mieke Uyttendaele, leads, together with Prof. Frank Devlieghere, the Food Microbiology and Food Preservation Research Group (FMFP-UGent) at Ghent University, Belgium. Her teaching and research area covers aspects of microbiological analysis of foods, food safety and food hygiene. She has built over twenty years of experience by executing, initiating and coordinating various projects in this research discipline dealing with sampling and testing to collect baseline data on the microbial contamination of foods, looking into the virulence of food-borne pathogens, elaborating challenge testing to study the behavior of food-borne pathogens. All this information serves as an input for quality assurance and microbial risk assessment to support food safety decision-making and setting microbiological criteria. She was/is the promotor of more than 25 Ph.D students (including EU and non-EU citizens). Throughout her career, Prof. Uyttendaele has published more than 270 peer reviewed scientific papers, authored several book chapters and presented at numerous international Conferences/Workshops. Throughout the years she has also used her scientific expertise in interpretation of test results for analyses obtained in routine monitoring or analysis executed at the food service lab at FMFP-UGent.

Statistical Aspects of the Microbiological Examination of Foods, Third Edition, updates some important statistical procedures following intensive collaborative work by many experts in microbiology and statistics, and corrects typographic and other errors present in the previous edition. Following a brief introduction to the subject, basic statistical concepts and procedures are described including both theoretical and actual frequency distributions that are associated with the occurrence of microorganisms in foods. This leads into a discussion of the methods for examination of foods and the sources of statistical and practical errors associated with the methods. Such errors are important in understanding the principles of measurement uncertainty as applied to microbiological data and the approaches to determination of uncertainty. The ways in which the concept of statistical process control developed many years ago to improve commercial manufacturing processes can be applied to microbiological examination in the laboratory. This is important in ensuring that laboratory results reflect, as precisely as possible, the microbiological status of manufactured products through the concept and practice of laboratory accreditation and proficiency testing. The use of properly validated standard methods of testing and the verification of ‘in house’ methods against internationally validated methods is of increasing importance in ensuring that laboratory results are meaningful in relation to development of and compliance with established microbiological criteria for foods. The final chapter of the book reviews the uses of such criteria in relation to the development of and compliance with food safety objectives. Throughout the book the theoretical concepts are illustrated in worked examples using real data obtained in the examination of foods and in research studies concerned with food safety. Includes additional figures and tables together with many worked examples to illustrate the use of specific procedures in the analysis of data obtained in the microbiological examination of foods Offers completely updated chapters and six new chapters Brings the reader up to date and allows easy access to individual topics in one place Corrects typographic and other errors present in the previous edition
