Food Safety News

Danish authorities have revealed three people died in an E. coli outbreak this past year. Imported spring onions were investigated as the source.

An update by the Statens Serum Institut (SSI) revealed that from Nov. 23 to Dec. 31, 2021, 85 people were infected with EIEC.

Enteroinvasive E. coli (EIEC) is usually associated with travel diarrhea but the patients had not been abroad.

It was previously reported that 68 people were ill in the outbreak linked to spring onions from Egypt via a Dutch supplier that were used in ready-to-eat salads.

Enteroinvasive E. coli was isolated from 36 patients and the remaining 47 were PCR positive for a gene specific to Shigella species and EIEC.

Further analysis identified two E. coli types in the outbreak: O136:H7 and O96:H19 with confirmation by whole genome sequencing.
