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 this study was to determine the prevalence of Salmonella sp. in pigs slaughtered in Rio Grande do Sui, Brazil. Mesenteric lymph nodes and intestine sections were sampled from 300 clinically healthy swine, at three different pork-slaughtering plants. Salmonella sp. was isolated in at least one of the samples collected in 167 animals, resulting in a prevalence of 55.66% (C.I 50.04 - 61.28). Twenty-six different Salmonella serovars were identified, being Typhimurium the most prevalent (24.3%), followed by Agona (19.9%), Derby (13.2%), and Bredney (12%). This results point the importance of implementing Salmonella control strategies in the south of Brazil.
