Food Safety News

Researchers have shed more light on the first recorded enteroinvasive E. coli (EIEC) outbreak in Sweden.

The outbreak in the county of Halland in 2017 had 83 self-reported infections and one secondary case attributed to household transmission, based on a study published in the journal Eurosurveillance.

Leafy greens were suspected to be behind the outbreak as this item was in a number of dishes associated with illnesses. There was no microbiological evidence to identify the source or vehicle of infection, but contaminated salad greens have been linked to previous EIEC outbreaks.

All five staff members at the conference and hotel venue that met the case definition had symptom onset at least one day after the first reported case among venue visitors.
