The Norway Institute of Public Health reports investigating an outbreak of gastrointestinal bacteria, Yersinia enterocolitica O:9. To date, 18 people from several counties have been diagnosed with the infection.
Health and Food Safety officials are are trying to determine if there is a common source of infection. Interviews are conducted with the patients, and samples from the homes are taken to find the source of infection, if possible.
“Investigations can be complicated and take time, and in many cases you will not be able to find the source of infection or to clarify if there is a common source”, says Solveig Jore Senior Adviser.
