CDC has declared that the 12-state outbreak of Salmonella Enteritidis is now over with 93 confirmed cases requiring 34 hospitalizations. EGG-NEWS reported previously on the outbreak associated with the farm located in Bonduel, WI.

Following traceback to the farm and an extensive recall of eggs, the incidence rate declined sharply.  Whole genome sequencing of isolates of SE from the farm and patients were homologous confirming the source of the infection.

Neither CDC nor FDA has released details concerning vaccination of the flock or the pattern of obligatory SE testing prior to the outbreak.
