A Yersinia outbreak in Norway has been solved and declared over just days after it was announced.
Folkehelseinstituttet (the Norwegian Institute of Public Health) said the national outbreak of Yersinia enterocolitica O3 was likely caused by a pre-mixed salad product.
Less than a week earlier, the agency had announced an investigation into a recent rise in Yersinia infections.
The outbreak started in mid-November and involved 10 confirmed patients. All of them are women aged 11 to 59 years old who became ill in mid to late November with the last case on Nov. 26. Three people live in Viken, two each in Oslo, Innlandet, and Vestland, and one in Telemark and Vestfold.
