Authorities in Norway are investigating a Salmonella outbreak that has affected nine people.
The Norwegian Institute of Public Health (Folkehelseinstituttet) said the patients became ill in January and early February. They are aged from 2 to 91 years old. The agency is investigating with local authorities, the Veterinary Institute (Veterinærinstituttet) and the Norwegian Food Safety Authority (Mattilsynet).
Five men and four women have been confirmed infected with Salmonella Agbeni. They live in Oslo, Akershus, Buskerud, Rogaland and Vest-Agder. Bacteria with a similar DNA profile has been detected in all nine people, which strongly suggests a common source. Officials are interviewing patients and sampling food leftovers to find the infection vehicle.
Officials from the Norwegian Institute of Public Health said such investigations can be complicated and take time with no guarantee the source of infection will be found. They added it was too early to say whether it is a limited outbreak or whether additional patients will be identified.
