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
This study aimed at investigating the Salmonella occurrence in two Spanish pig slaughterhouses analysing the lairage, slaughter line, carcasses and the cutting plants thereof. The results obtained showed a decrease of Salmonella prevalence from the lairage to the cutting plant. The high levels of contamination in holding pens and several points of the slaughter line point them out as the major risk sources of Salmonella spreading within the slaughterhouse. The main Salmonella serotypes previously reported in Spanish finishing pig farms were found at both slaughterhouses. S. Typhimurium isolates recovered from different points of the slaughter chain were typed by MLVA.
