Yelp helped NYC find unreported food borne illness: report

Reviewers on the online restaurant and business rating site, Yelp, helped New York City health officials find hundreds of unreported cases of possible food borne illnesses, health officials reported on Thursday. Researchers involved in a pilot project between the New York City Department of Health and Mental Hygiene, Columbia University and Yelp trawled the site for reviews that included words like "sick," "vomit," "diarrhea" and "food poisoning," between July 2012 and March 2013. Roughly 294,000 Yelp reviews were analyzed, and researchers found 468 posts that were consistent with cases of recent food borne illnesses.
