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.
