This classic, definitive reference work for all those involved in environmental health is now available in its 19th edition. Significant changes include those made to chapters on food safety and hygiene, environmental protection, the organisation and management of environmental health in the UK, port health, and waste management. New chapters have been added on health development, an introduction to health and housing, contaminated land, and environmental health in emergency planning, as well as a new glossary of abbreviations and acronyms. New material on training and standards, IT, practical risk assessment, and investigatory powers is also included. Each chapter reflects the wider background against which the subjects must be studied and the new concepts and approaches that have emerged over the past few years.
