The built environment harbours micro-organisms specifically adapted to that environment. Cross-contamination with these could compromise both food safety and quality. Targeted cleaning (e.g. contact surfaces) can maintain day-to-day control of problem micro-organisms but not eliminate them. Work at CCFRA has established that microbial strains can persist in food factories for several years. Alternative technologies have been developed to improve control over the whole food processing area; however, the effectiveness and practical operation of these has not been assessed. This project would address this to provide guidance on their selection and use. It will explore new ways of combating pathogenic and spoilage micro-organisms, including persistent strains, provide guidance on the suitability, selection and installation of novel decontamination systems, and develop procedures for evaluation of the effectiveness of new approaches to disinfection.
