According to a report just released by the Southern Nevada Health Department, as of May 5, 2013 at least 196 patrons and 4 employees of Firefly who consumed food and/or drinks at Firefly restaurant during April 21-26, 2013 have been determined to be confirmed or probable cases of Salmonella infection. From various surveillance data sources, reports of illness from restaurant patrons who normally reside in twenty states:
Arizona, California, Colorado, Hawaii, Illinois, Massachusetts, Minnesota, Mississippi, North Carolina, New Hampshire, Nevada, Ohio, Oklahoma, Oregon, Pennsylvania, South Carolina, Texas, Utah, Washington and two foreign countries (Canada, United Kingdom).
Illness onset dates occurred within the April 22 to May 1, 2013 time frame. The onset date with the peak number of ill restaurant patrons was April 24, 2013. Because the incubation period for Salmonella is usually 12-36 hours, this might suggest that patrons who ate at Firefly on April 22-23, 2013 had the highest risk of exposure to the pathogen.
According to some there is a call to name this species as Salmonella Firefly – after the restaurant.
Serotyping of the isolates indicated that the outbreak strain was Salmonella (assigned with the antigenic code “I:4,5,12:i:-”.
