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

Täglich werden in Europa tausende mikrobiologische Analysen durchgeführt, besonders zur Überwachung der Qualität von Lebensmitteln, Trinkwasser oder Badegewässern. Um Proben und Messergebnisse im gesamten europäischen Raum vergleichen und austauschen zu können, sind einheitliche Qualitätsstandards Voraussetzung. Diese wurden in verschiedenen EU-Projekten erarbeitet und unterstützt von der Europäischen Kommision in entsprechenden Richtlinien formuliert. Dabei wurde die EN 45001 zugrunde gelegt (nun ersetzt durch die Norm ISO/IEC 17025 "Allgemeine Anforderungen an die Kompetenz von Prüf- und Kalibrierlaboratorien"). Insbesonders gehören dazu: zuverlässige Referenzmaterialien, anerkannte Mess- und Auswertmethoden sowie validierte Abläufe von der Probennahme bis zur Dokumentation der Ergebnisse. Mit den nun auch in Deutsch vorliegenden Anleitungen kann jedes Untersuchungslabor ein Qualitätssicherungssystem implementieren.

Mathematical and Statistical Approaches in Food Science and Technology offers an accessible guide to applying statistical and mathematical technologies in the food science field whilst also addressing the theoretical foundations. Using clear examples and case-studies by way of practical illustration, the book is more than just a theoretical guide for non-statisticians, and may therefore be used by scientists, students and food industry professionals at different levels and with varying degrees of statistical skill.

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 Criteria have been used in food production and the food regulatory context for many years. While the food-specific aspects of microbiological criteria are well understood, the mathematical and statistical aspects are often less well appreciated, which hinders the consistent and appropriate application of microbiological criteria in the food industry. This document has been developed to begin redressing this situation. A particular aim of this document is to illustrate the important mathematical and statistical aspects of microbiological criteria, but with minimal statistical jargon, equations and mathematical details. It is hoped that the resulting document and support materials make this subject more accessible to a broad audience. This volume and others in this Microbiological Risk Assessment Series contain information that is useful to both food safety risk assessors and risk managers, the Codex Alimentarius Commission, governments and regulatory agencies, food producers and processers and other institutions and individuals with an interest in Microbiological Criteria. This volume in particular aims to support food business operators, quality assurance managers, food safety-policy makers and risk managers.
