Dr Elizabeth Scott

Elizabeth ScottAssistant Professor in the Department of Biology, Director Of Undergraduate Program in Public Health, Co-director Simmons Center for Hygiene and Health in Home and Community, Simmons College, Boston MA USA.

Dr Elizabeth Scott is an authority on consumer food hygiene and general hygiene issues, and is one of only a few people who have a working knowledge of the subject in both North America and Europe. Her current interests include developing a common approach to hygiene concerns in community settings based upon an understanding of the risk of infection acquisition & transmission in home & related community settings.

Dr Scott has both a Master&;s degree and Ph.D. in microbiology and has spent twenty years researching, teaching and advising in the field of food and environmental hygiene in the commercial and consumer sectors. Her research project for the Master&;s degree was a three-year study of the bacterial content of the domestic environment and examined the effectiveness of disinfectants in the home. This work remains the largest published study on the bacteriology of the home (Scott 1981). Research for her Ph.D. at London University looked at the survival and transfer of potential pathogens on inanimate surfaces and provided further insight of the chain of events which can result in errors of hygiene and cause outbreaks of foodborne disease (Scott 1990).

Dr Scott has published widely on aspects of hygiene in the home and the prevention of foodborne illness and is a regular contributor at national and international conferences and seminars. She is one of the first people to bring the subject to the attention of the American scientific community when she convened a seminar at the 1996 American Society of Microbiologists General Meeting in New Orleans on the subject of Foodborne Diseases in the Home She has recently contributed papers at the WHO Europe Symposium on Housing and Health in Italy ( 2002), the UWO Stanier Symposium in Canada ( 2002) & the Japan Society for Antibacterial & Antifungal Agents ( Osaka, 2001).For many years Dr Scott was involved in informing the British public about food hygiene issues via public speaking engagements, television, radio and press articles. In 1993 she moved to the United States and now has professional interests on both sides of the Atlantic.

Dr Scott is active as a consultant in food and environmental hygiene in both home and community settings and her expertise enables her to advise on hygiene issues, hygiene research and hygiene education. In addition, she is an Associate Professor in the Biology Department at Simmons College in Boston.

In June 1998, her first book was published, co-authored with Dr Paul Sockett of the Bureau of Communicable Disease Epidemiology, Canada. Entitled How to Prevent Food Poisoning: A Practical Guide to Safe Cooking, Food handling and Eating. This consumer guide combines practical advice with scientific information to give people a real understanding of the subject and issues.
