The control of E.coli 0157 has been at the heart of the environmental health practitioner's professional agenda since the UK's largest outbreak in Lanarkshire in 1996. The key to controlling the organism lies in ensuring the microbiological safety of food, drinking and recreational water and the prevention of direct spread from animal outbreaks. This book is aimed at health professionals who need to be fully informed about the sources and effects of the organism in order to provide advice and enforce legislation at local level as well as providing non specialist professionals including food industry managers with a practical introduction to the terminology, methods and issues surrounding the diagnosis and control of E.coli.
