During the middle of May, an number of reported cases of Yersinia infection has been seen in Sweden. Seven regions from different parts of the country have reported cases, but the majority of cases come from the northernmost regions of the country.

So far, 26 cases of disease have been confirmed to belong to the outbreak by means of whole-genome sequencing. Another handful of cases are investigated. Since the current outbreak strain of Yersinia enterocolitica type O3 has been found in different parts of the country, it is likely that a food borne infection. The current outbreak strain differs from the one that caused a Yersinia outbreak earlier in the spring.

Yersiniosis is an infection caused most often by eating raw or undercooked pork contaminated with Yersinia enterocolitica bacteria.
