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
The objective of the study was to investigate the assoctatwn of farm management factors with the detection of Salmonella in lymph nodes of pigs at slaughter. Samples were collected in German abattoirs in the course of the EU baseline study on Salmonella in slaughter pigs from October 2006 to September 2007. A minimum of 5 lymph nodes (>15 g sample weight) were collected from pigs at slaughter and examined for Salmonella according to IS06579:2003, Annex D. Data were collected using a standardized data capture form to be filled in by the veterinary officials. Additional information was available in a subsample (85112569) of the pigs included in that study. The association of factors was tested using univariate and multivariate logistic regression. Separate analyses were run for a: Salmonella spp., b: specifically for S. Typhimurium, the most prevalent Salmonella serovar in the study population and c: for all other serovars grouped together.
