Yersinia enterocolitica and Y. pseudotuberculоsis are the causative agents of foodborne zoonosis called yersiniosis. In 2011 it was the forth most commonly reported zoonosis in EU, nevertheless the tendancy of decreasing five-year trend (2007-2011). Yersiniosis is reported анд десцрибед in different animal species, e.g. wild animals and birds. Both enteropathogenic bacterial agents are ubiquitous and easily adaptable to the environment, what is an important precondition for infection of a wide variety of animals and contamination of water, soil, feed, vegetables, etc. Concidering the growing public health concern for human pathogenic biotypes and serotypes of Yersinia, as well as the role of slaughter pigs as major reservoir for the foodborne transmission of Y. enterocolitica, essential microbiological experimental findings and epidemiological data are presented. Molecular approaches for detection and identification are discussed too
