The SafePork conference series began in 1996 to bring together international researchers, industry, and government agencies to discuss current Salmonella research and identify research needs pertaining to both pig and pork production. In subsequent years topics of research presented at these conferences expanded to include other chemical and biological hazards to pig and pork production.

Abstract
Salmonella (S.) Choleraesuis var. Kunzendorf is the major cause of swine salmonellosis in Poland. Eleven XbaI macrorestriction profiles and 3 ribotypes were noted amongst 36 isolates tested. Index of discrimination reached 0.88. Two clonal lineages were distinguished. One of the lines embraced the majority of 2000-2002 isolates showing over 80% genome similarity. The findings prove the clonal spread of the pathogen among swineherds in Poland.
