In 2021, yersiniosis was still, the third most frequently reported human zoonosis in Europe, (EFSA and ECDC, 2021) with Yersinia enterocolitica being the most common Yersinia species reported in human cases. Pigs are frequently described as a source of human contamination by Y. enterocolitica through consumption of raw or undercooked meat or by direct contact with contaminated carcasses. Pigs carry Y. enterocolitica in their oral cavities, and they excrete this bacterium in their feces. A one-year French survey at slaughterhouses indicated that 13.7% of the pigs were found positive for pathogenic Y. enterocolitica and 74.3% of the pig batches contained at least one positive pig (Fondrevez et al., 2014). Biotype 4 (BT4) was the most prevalent biotype among the isolated strains (91.9% of the isolates). This BT4 is also the most common biotype found in human infections in France (79% according to the Yersinia French National Reference Laboratory).
