[An outbreak of Salmonella enteritidis at the New Year celebration of the Copenhagen Medical Association].
In order to determine the extent and infectious vehicle of an outbreak of Salmonella enteritidis phage type 6 at the New Year celebration of the Copenhagen Medical Association on 15 January 1999, a cohort study including 77 guests (90% of the participants) and 11 staff was carried out. There was little variation in the degree of exposure among the guests, meaning that identification of the probable infectious vehicle was not possible here. However, among the staff, intake of minced raw salmon was associated with increased risk of disease. Uncooked eggs were used in the preparation of this dish and since S. enteritidis phage type 6 is in Denmark almost exclusively found among egg-laying hens, these findings led to the conclusion that the outbreak was most likely caused by the use of raw eggs. The importance of notification of suspected foodborne disease and microbiological examination of people thereby exposed is stressed.
