Yersiniosis – Norway
- January 27, 2021
- < 1 min read
A national outbreak of Yersinia started in mid-November.
The source of infection for the national outbreak with Yersinia enterocolitica is probably a ready-cut lettuce product, according to the investigation of the outbreak. The outbreak is considered over.
Ready-cut lettuce has a short shelf life and the contaminated product will therefore no longer be on the market.
Salad products have also on previous occasions caused outbreaks of gastrointestinal disease in this country.
Yersiniosis is an infectious disease caused by a bacterium of the genus Yersinia. Most infections among humans are caused by Yersinia enterocolitica. The infection mostly contracted through the consumption of undercooked meat products, raw vegetables, unpasteurized milk, or water contaminated by the bacteria.
Yersiniosis is usually self-limiting and does not require treatment.
