title: A foodborne outbreak of Salmonella enterica subsp. enterica serovar Madelia at a silver anniversary reception.
abstract: Reported here is an outbreak of Salmonella enterica subsp. enterica serovar Madelia infection that occurred among 44 persons attending a silver anniversary reception in Hesse, Germany. Isolates of Salmonella Madelia are extremely unusual, and no outbreaks associated with this serotype have been reported previously. Forty-two attendees were interviewed and information was obtained from each of them regarding demographic and clinical characteristics and food consumed at the reception. Twenty-four attendees submitted stool samples for microbiological testing, and 10 of these were culture-positive for S. Madelia. Twenty-three attendees met the case definition of infection, while 18 met the clinical case definition (i.e. vomiting or diarrhoea within 3 days of consuming food at the reception) and five had asymptomatic infection with S. Madelia. The most likely vehicles of infection were tortellini and a red pesto sauce.
