Multiple cities are investigating Salmonella Enteritidis infections linked to eating at Fig & Olive restaurants, the U.S. Centers for Disease Control and Prevention tells Food Safety News. Illnesses have so far been reported Washington, D.C., and Los Angeles, and the investigation is ongoing to determine whether there are illnesses in other states linked to eating at one of the other locations owned by the New York-based chain. The Los Angeles County Department of Public Health tells FSN that, as of Oct. 2, 39 people may have been sickened with Salmonella after eating at the Fig & Olive restaurant in West Hollywood between Sept. 6-11, 2015. Of these, eight cases have been confirmed by laboratory tests. Two people have reportedly been hospitalized, and there have been no related deaths.

The same type of Salmonella sickened at least 60 people in Washington, D.C., and five states from late August through early September. An additional 150 cases are being investigated. CDC is coordinating a multistate investigation with the Washington, D.C., Department of Health, the Los Angeles County Department of Public Health, the U.S. Food and Drug Administration, and other states which have Fig & Olive restaurant locations. Marler Clark (the Seattle-based law firm which underwrites FSN) reports that several people who had eaten at a Fig & Olive location in New York City developed Salmonella infections. The New York City Department of Health and Mental Hygiene has so far not identified any illnesses among city residents associated with Fig & Olive restaurants. In addition to the D.C. and West Hollywood locations, Fig & Olive has three restaurants in New York City, one in Scarsdale, NY, one in Newport Beach, CA, and one in Chicago. The source of the infections has not yet been identified, but the NBC affiliate in Washington reports that LaQuandra Nesbitt, director of the D.C. Department of Health, said that the truffle fries and mushroom croquettes were most likely to blame. “We will advise the public if specific steps are identified that consumers can take to protect themselves,” CDC stated. “People with concerns about eating at a Fig & Olive restaurant location should contact their local health department.” Fig & Olive has not responded to a request for comment on the situation.
