Health officials in Norway are reporting an E. coli O157: H7 outbreak that has sickened six people since June.
The six patients reside in different counties–Akershus, Oslo, Vestfold, Hordaland and Trøndelag.
The Norwegian Institute of Public Health is cooperating with the municipal health service and the Norwegian Food Safety Authority and the Veterinary Institute to investigate whether the patients may have 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. Investigative work can be complicated and take time, and in many cases it will not be possible to find the source of infection or to clarify whether it is a common source”, says Solveig Jore, senior adviser at the National Institute of Public Health.
