As clean as they look? Food hygiene inspection scores, microbiological contamination, and foodborne illness

Abstract

This work describes the relationship between compliance with food hygiene law as reflected in food hygiene scores; measures of microbiological contamination of food samples taken from consumer-facing food businesses in England, Northern Ireland and Wales; and outbreaks of foodborne illness. This paper demonstrates an association between the results of food hygiene inspections done by trained inspectors, using a rigorous and consistent procedure, with microbiological contamination of actual food samples from those premises. A proposed theoretical model further demonstrates the reduction in foodborne illness that would result if there were increased compliance with food hygiene law.
