Whole room disinfection: A new concept in food industry sanitation

28 February 2008 | By Dr. Karen Middleton, Technical Contracts Manager, Food Hygiene Department, Campden & Chorleywood Food Research Association, UK

During manufacture, food can be exposed to microbiological cross-contamination from surfaces and air which may give rise to food spoilage and safety issues. The traditional approach to controlling such contamination has been to target specific sites within the manufacturing environment with cleaning and disinfection regimes.

Developments in food refrigeration

23 May 2007 | By Judith Evans, Senior Research Project Manager, FRPERC (Food Refrigeration and Process Engineering Research Centre), University of Bristol

Refrigeration is a vital part of modern food production. Without a means to cool and keep food cold, the quality and safety of food would be compromised and the sophisticated cold chain we are used to would not be possible. The whole food chain is underpinned by refrigeration from primary…
