Traduction en anglais : Investigation of a foodborne outbreak due to Salmonella infantis using epidemiological and microbiological methods.
In foodborne outbreaks, direct microbiological diagnosis is often not possible due to lack of remaining food samples.
Therefore, in this investigation of an outbreak of Salmonella infantis at a fair, we chose an epidemiological approach in addition to microbiological testing.
In a case control study, fair participants with symptoms of acute gastroenteritis as well as participants showing no signs of disease were interviewed by telephone.
Questions concerning what food had been eaten at the fair and the course of disease had priority.
Data analysis showed a significantly elevated odds ratio of 144 (p<0,00001) for the consumption of potato salad.
Salmonella infantis was cultured in faeces of symptomatic individuals as well as from left-over potato salad in high concentration.
In conclusion, our data show that the cause of a foodborne outbreak can be detected through the application of epidemiologic methods with a high degree of certainty.
In order to eliminate memory bias, a structured interview should be carried out as soon as possible after the initial outbreak.
