MODELING RISK OF FOODBORNE ILLNESS OUTBREAKS
First Claim
1. A method comprising:
- receiving inspection data from a plurality of restaurants that each experienced at least one associated foodborne illness outbreak;
receiving inspection data from a plurality of restaurants that did not experience any foodborne illness outbreaks;
mapping the inspection data from the plurality of restaurants that each experienced an associated foodborne illness outbreak to a standardized set of survey questions;
mapping the inspection data from the plurality of restaurants that did not experience any foodborne illness outbreaks to the standardized set of survey questions; and
identifying a set of one or more indicative violations from among the standardized set of survey questions that were recorded more frequently in the restaurants that experienced at least one associated foodborne illness outbreak than in the restaurants that did not experience any foodborne illness outbreaks.

Abstract
A foodborne illness risk model determines a relationship between health department inspection data and various factors known to contribute to the risk of foodborne illness. The model may identify a comparative risk value for foodborne illness outbreaks for one or more pathogens at a food establishment based on the food establishment'"'"'s inspection data. The model may also identify a set of indicative violations more likely to be recorded at outbreak restaurants than non-outbreak restaurants. The model may also develop an outbreak profile continuum based on the number of indicative violations. The model may further determine a position on an outbreak profile continuum for a particular food establishment based on the food establishment'"'"'s inspection data.
