Whilst much is known about how contamination arises, and control methods are well understood, there is no room for complacency; every microbiologist knows that from time to time a contamination issue inevitably will arise and must be promptly addressed. Detailed practical guidance on appropriate microbiological methods is an absolute necessity if such problems are to be resolved speedily and to the satisfaction of all involved. This handbook attempts to fulfil this role in the laboratory, bringing together a wealth of information from diverse sources into a single volume. The reader is guided throughout the book by the advice and recommendations of expert contributors with an in-depth knowledge and personal experience of the likely practical issues to be faced by those working in the microbiology laboratory. Beginning with safety concerns and the design of laboratory facilities, guidance is provided on the choice and requirements of culture media, followed by a detailed consideration of specialized microbiological methods, including chapters on sampling, enumeration and identification of micro- organisms, involving both traditional and rapid techniques, sterility testing, environmental monitoring, preservative efficacy testing, endotoxin testing and antibiotic bioassays. Whilst established reference methods are of necessity included here, there is also an abundance of information on how these tests are interpreted in common practice. Cleaning and disinfection considerations, frequently a much neglected subject, are also addressed within this volume. Hazard analysis and audit approaches complete the routine tasks facing the company microbiologist and the reader is directed in how this might be successfully achieved. Finally, a number of worked case examples have been included to assist those involved in such every day calculations. Although the book is intended as a complete reference source in its own right, it is in fact a companion book to the Guide to Microbiological Control in Pharmaceuticals and Medical Devices, shortly to be published in its second edition by Taylor and Francis. The intention here was to provide in the Handbook detailed practical information on methodology of the techniques advocated and identified for microbiological quality control in the Guide. The Handbook is therefore extensively cross-referenced to the Guide, and it is hoped that the collected wisdom of these two books provides the laboratory microbiologist with a unique, valued and much consulted reference source.
