Human illness attributed to foodborne pathogenic microorganisms has been prominent in the mass media in recent years. The Practical Food Microbiology Series has been devised to give practical and accurate information about specific microorganisms of concern to public health. This series is unique in its practical approach as it draws on real life situations to highlight practical means for controlling pathogenic microorganisms in foods. Listeria monocytogenes has been recognised as an animal pathogen for over 70 years, and in the last two or three decades concern has been focused on the role of food in the transmission of human listeriosis, and also on L. monocytogenes as a cause of febrile gastroenteritis. This second edition has been fully revised and updated to include the latest information on L. monocytogenes, including its taxonomy, details of recently documented outbreaks implicating the organism, and legislation relating to the organism. The book aims to give the reader an overview of Listeria and particularly L. monocytogenes.
It is primarily intended as an aid for those persons who want to understand the nature of the hazard that this organism presents to food products, and the means of controlling it. The information is designed for use by those in the food industry working in manufacturing, retail, and quality assurance; those in associated professional sectors, e. g. healthcare; as well as students in each of these areas. The book is an invaluable tool and essential reference for all food microbiologists.
