Sally Bloomfield qualified initially as a pharmacist, but then went on to develop a career in microbiology, with a specific interest in the prevention of infectious diseases and in microbial quality assurance. For 25 years, Dr Bloomfield was an academic in the Department of Pharmacy, Kings College London.

During this time, her research interests were mainly concerned with the study of antimi¬crobial agents used in the community and in medicine. Most particularly, she was involved in studying the molecular and physiological basis for the development of resistance to antimicrobial agents. She was also involved in a range of projects studying the role of hygiene, including the role of cleaning and disinfection, in preventing the spread of infectious disease in the hospital, food processing, domestic and other environments.

From 1997 to 2003 Dr Bloomfield joined Unilever Research to develop a programme involved with raising awareness of the importance of hygiene in the domestic setting. During this time was involved in setting up the International Scientific Forum on Home Hygiene (IFH) (

In 1995, Dr Bloomfield was awarded the Rudolf Schulke Hygiene Prize, for outstanding contribution in the field of Hygiene and Preventive Medicine. She was also a member of Comité Européen de Normalisation - CEN TC 216 - Antiseptics and Disinfectants – from 1990-2003.

Teaching & Research

Dr Bloomfield currently acts as a consultant in hygiene and infectious disease with particular reference to the home setting. She is Chairman and Member of the Scientific Advisory Board of IFH.

Through these roles she is continuing to develop her work in raising awareness of the importance of home hygiene in preventing the transmission of infectious disease, and developing and promoting home hygiene practice based on sound scientific principles. She is also working to develop understanding of “hygiene issues” such as the “hygiene hypothesis” and “antimicrobial resistance”.
