Spring onions from Egypt suspected in 2021 Danish E. coli outbreak
date:Apr 28, 2023
reported from other European countries. However, in 2021, the UK had an outbreak of Shigella sonnei where spring onions from the same producer in Egypt were the suspected source.

As it was the first EIEC outbreak in Denmark, there was no standard questionnaire available, so a trawling questionnaire usually used for Shiga toxin-producing E. coli (STEC) and Salmonella outbreaks were employed. Culture-independent diagnostic tests (CIDT) also made separating outbreak and sporadic cases difficult.
