FOREWORDThe Microbiology Handbook series includes Dairy Products, Fish and Seafood, and Meat Products, published by Leatherhead Food International and RSC Publishing. The books in the series are designed as easy-to-use guides to the microorganisms found in foods. Each book provides a brief overview of the processing factors that determine the nature and extent of microbial growth and survival in the product, potential hazards associated with the consumption of a range of products, and growth characteristics for key pathogens associated with the product. All handbooks also contain a review of the related legislation in Europe and UK, guides to HACCP, and a detailed list of contacts for various food authorities. The books are intended as a source of information for microbiologists and food scientists working in the food industry and responsible for food safety, both in the UK and elsewhere.

Acknowledgements

All the authors involved in writing the first edition of this book are gratefully acknowledged. I thank the contributing authors for their collaboration, which has been the chief factor in ensuring the completion of this book. My gratitude is extended to Dr Peter Wareing, Training Manager, for his scientific input and Victoria Emerton, Technical Team Leader for her valuable editorial contribution. I also acknowledge and thank Jackie Apps, Alison Turner, and Ann Pernet for the work put into typesetting and indexing. I dedicate this book to my husband - Goldwyn; thank you for all the support.

INTRODUCTIONFish and seafood are a main source of animal protein in the diet. Because of their health advantages over red meats, the consumption of fish and seafood has increased. Catches can be gathered from seas, rivers and lakes whose water can range from pristine to contaminated. Often contamination is from human and animal sources; thus, fish and seafood can be involved in the transmission of pathogenic microorganisms and toxins. Geographical region, season, and, for fish, whether they are pelagic (surface to mid-water) or demersal (bottom) feeders will influence the numbers and types of microorganisms present on freshly caught seafood. The Microbiology Handbook- Fish and Seafood consists of the microbiology of seven different product categories: chilled and frozen raw fish, chilled and frozen prepared fish, molluscan shellfish, crustacean shellfish, cured, smoked and dried fish, fermented fish, and fish and shellfish toxins. The second edition of this handbook is a review of the entire book for currency of information. Key changes in this edition are the recent regulatory changes pertaining to food hygiene and microbiological criteria for foodstuffs. Further Reading General Fish/Seafood MicrobiologyCross N.
