Scores on doors: restaurant hygiene ratings and public health policy.

This paper seeks to contribute to the ongoing policy debate about mandated posting of health department hygiene ratings for establishments that sell food. Posted restaurant hygiene ratings, or 'scores on doors,' exemplify a public health transparency policy in the form of words, letters, numbers, or symbols displayed at entrances to food-serving establishments summarizing their most recent health inspection. After describing the scope of restaurant hygiene inspections and the problem of foodborne illness, this paper critically examines the 'mandation' debate on economic, practical, ethical, and legal aspects. It concludes that mandated posting of hygiene ratings, if done properly, is a potentially effective public policy that fosters transparency, population health, and informed consumer choice.
