Ever-increasing public interest and concern over food safety, as well as commercial pressure to improve food quality and extend product shelf life, have greatly increased the responsibility and accountability of all those involved in the microbiological examination of foods and food-related samples. In order to maintain the consistently high standards of laboratory practice that are required in food microbiology, all staff must be suitably trained to understand what they are to do, how they are to do it and why they must do it in a prescribed way. Properly trained laboratory staff are a valuable asset, whether they work in a food industry, public health, research or contract testing laboratory, and they make a significant contribution to the reliability of the results obtained from microbiological examinations of food samples. This book is an essential training aid and reference for all trainees in food microbiology laboratories, as well as their teachers, their trainers and all those attending food microbiology training courses. It provides an up-to-date, comprehensive working knowledge of all areas of basic food microbiology, with particular focus and emphasis on laboratory-based, practical aspects. Information and comment is provided on:- groups of microorganisms of importance in food microbiology: factors affecting the growth, survival and death of microorganisms in foods food spoilage, food-borne illness and food preservation applications of microbiology in the food industry laboratory design, equipment, operation and practice laboratory accreditation, performance monitoring and systems for documentation use of laboratory equipment, basic techniques and obtaining samples conventional methods for microbiological examination confirmation tests and how they work, and an introduction to 'alternative' microbiological methods Each topic is accompanied by further information sources that will help in the development of high standards for the next and future generations of practical food microbiologists. Provides a fully up-to-date working knowledge of all aspects of food microbiology with a particular focus on practical laboratory aspects. Focuses on laboratory methodology and how to get good results.
Introductory Microbiology Lab Skills and Techniques in Food Science covers topics on isolation, identification, numeration and observation of microorganisms, biochemistry tests, case studies, clinical lab tasks, and basic applied microbiology. The book is written technically with figures and photos showing details of every lab procedure. This is a resource that is skills-based focusing on lab technique training. It is introductory in nature, but encourages critical thinking based on real case studies of what happens in labs every day and includes self-evaluation learning questions after each lab section. This is an excellent guide for anyone who needs to understand how to apply microbiology to the lab in a practical setting. - Presents step-by-step lab procedures with photos in lab setting. - Includes case studies of microorganism causing infectious disease. - Provides clinical microbial lab tasks to mimic real-life situations applicable to industry.
This book provides a general but thorough overview of basic microbiological techniques, analytical methods and advanced tests for food-borne pathogens, procedures for detecting pathogens in food, as well as beneficial microorganisms and their role in food fermentations. Both specialists looking to refresh their understanding of microbiology and those working in the food industry without a background in microbiology will find this book useful.
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
Microbiological Analysis of Foods and Food Processing Environments is a well-rounded text that focuses on food microbiology laboratory applications. The book provides detailed steps and effective visual representations with microbial morphology that are designed to be easily understood. Sections discuss the importance of the characteristics of microorganisms in isolation and enumeration of microorganisms. Users will learn more about the characteristics of microorganisms in medicine, the food industry, analysis laboratories, the protection of foods against microbial hazards, and the problems and solutions in medicine and the food industry. Food safety, applications of food standards, and identification of microorganisms in a variety of environments depend on the awareness of microorganisms in their sources, making this book useful for many industry professionals. - Includes basic microbiological methods used in the counting of microbial groups from foods and other samples - Covers the indicators of pathogenic and spoilage microorganisms from foods and other samples - Incorporates identification of isolated microorganisms using basic techniques - Provides expressed isolation, counting and typing of viruses and bacteriophages - Explores the detection of microbiological quality in foods
