Program tracks when foodborne illness 'goes viral' on Twitter
Your next tweet could help track a Salmonella outbreak to a restaurant source if a new computer program from researchers at the University of Rochester enters common use. The system, called nEmesis, combines machine-learning and crowdsourcing techniques to analyze millions of tweets to find those from restaurant patrons discussing foodborne illness after eating at a particular location.
Some cases in multistate outbreak tied to salad mix from Mexican source
Cases of the illnesses caused by the single-celled Cyclospora parasite have been reported in 22 states to date, but the FDA and CDC say that it is not yet clear whether all cases are part of the same outbreak. A source has been confirmed for cases in only two states, Iowa and Nebraska. In those states, a traceback investigation linked the infections to a salad mix supplied to Olive Garden and Red Lobster restaurants by a Mexican supplier.
