| Zusammenfassung: | <jats:title>SUMMARY</jats:title><jats:p>The aim of this study was to identify the sources of sporadic domestic <jats:italic>Salmonella</jats:italic> cases in Sweden and to evaluate the usefulness of a source-attribution model in a country in which food animals are virtually free from <jats:italic>Salmonella</jats:italic>. The model allocates human sporadic domestic <jats:italic>Salmonella</jats:italic> cases to different sources according to distribution of <jats:italic>Salmonella</jats:italic> subtypes in the different sources. Sporadic domestic human <jats:italic>Salmonella</jats:italic> cases (<jats:italic>n</jats:italic>=1086) reported between July 2004 and June 2006 were attributed to nine food-animal and wildlife sources. Of all <jats:italic>Salmonella</jats:italic> cases, 82% were acquired abroad and 2·9% were associated with outbreaks. We estimated that 6·4% were associated with imported food, 0·5% with food-producing animals, and 0·6% with wildlife. Overall, 7·7% could not be attributed to any source. We concluded that domestic food-producing animals are not an important source for <jats:italic>Salmonella</jats:italic> in humans in Sweden, and that the adapted model is useful also in low-prevalence countries.</jats:p> |
