THE Handbook of Food Microbiological Analytical Methods includes 31 topics and experiments distributed throughout five chapters, namely basic microbial skills, the enumeration of different microorganisms in foods, identification techniques and determination of microbial activities. Besides, the handbook includes useful sources in food microbial analyses such as the Food Microbiology E-sources and the primers for identification of common microbial pathogens. This handbook aims to provide and develop concerning food microbial skills in the users with simple steps to follow along with the theoretical explanation for better understanding. The uniqueness of this handbook includes topics that are rarely addressed in current food microbiology manuals and handbooks such as the enumeration of special bacterial groups such as marine and Gram-positive bacteria, introducing: A selective medium for enumeration of Gram-positive bacteria from marine sources for the first time; a technique for bacterial colonies randomisation; a technique for recovery of injured/stressed bacteria; techniques to study bacterial potential such as spoiling foods; a technique that forms biogenic amines; and the production of antimicrobial activity and providing the specific specie primer pairs for common pathogens. The principles and procedures of some routinely used identification techniques namely vitek, sequencing of 16S rRNA gene and specific genus and specie primers for bacterial identification are provided with simple procedures. Enumeration and identification techniques of common pathogens and spoilers, namely Staphylococcus aureus, Enterobacteriaceae, Escherichia coli, Salmonella spp., Listeria monocytogenes, Vibrio parahaemolyticu, Bacillus cereus and Shewanella putrefaciens enumeration and identification techniques are also covered. These techniques are based on the International Standards such as ISO and U.S. Food and Drug Administration Standards and the medias manufacture instructions. This handbook is needed to conduct microbial analyses to determine food microbial quality and safety, food hygienic status and the microbial potential to spoil food, lose food safety and produce antimicrobial activity. This handbook was prepared to be used by students and young researchers. Therefore, it can be used in the universities as a practical manual in biology, microbiology, food microbiology, food safety, and food hygiene courses, as well in food laboratories which determine food microbial safety and quality. It is expected that this handbook will be a good and practical guide for students and researchers as well.

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

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.
