In a follow-up on the Yersinia enterocolitica O3 outbreak in Norway, the Norwegian Institute of Public Health says the source of the outbreak is likely a pre-cut lettuce product, the investigation concludes.
The National Institute of Public Health’s analysis of patient interviews shows that everyone states that they have eaten a pre-cut salad product the week before illness.
Lettuce has a short shelf life and the relevant salad products are probably no longer on the market and the outbreak is considered over, says senior researcher Umaer Naseer at the National Institute of Public Health.
Which lettuce raw material is the probable source of infection in this outbreak is further investigated.
The outbreak of Yersinia enterocolitica O3 started in mid-November. In total, as of 21 December, there are 10 confirmed cases. Everyone has become ill in the period from mid to late November. The latter became ill on 26 November. The persons live in Oslo (2), Viken (3), Innlandet (2), Vestland (2) and Telemark and Vestfold (1). They are all women aged 11-59 years.
