Impact of internet posting of restaurant inspection scores on critical violations.

Posting restaurant inspection scores on the Internet as a tool for improving food safety is becoming more common. The purpose of the study described in this article was to evaluate the association between Internet posting of restaurant inspection scores and the five most frequently cited critical violations in Salt Lake County, Utah. The study examined 2,995 inspections conducted at 796 full service and fast food restaurants for a one-year period before and after launch of a restaurant inspection Web site. Critical violations decreased significantly after the Web site launch compared to before-launch levels. The greatest improvements were found in temperature holding violations (odds ratio = 0.75, p < .001), hygiene practices violations (odds ratio = 0.68, p < .001) and equipment cleanliness violations (odds ratio = 0.58, p < .001). Restaurant type (full service, fast food), inspector experience, and season were significantly associated with the decrease in violations.
