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 effects of meal feed, potato protein concentrate (5 %), beet pellets (10 %), a barley-based diet and zinc gluconate (0,05 %) on Salmonella prevalence, gastro-intestinal health and productivity in finishers were examined. The study comprised a total of 1.224 pigs and was designed as a randomised block test with six test groups and 20 replicates. The results showed that meal feed and dried sugar beet pulp (SBP) reduced Salmonella prevalence significantly compared to a pelleted diet. The reduction and changes in the microbial system when SBP was added was not as significant as with meal feed. Contrary to meal feed, SBP did not reduce the production value significantly. It was not possible to prove any effects of potato protein concentrate, barley or addition of zinc gluconate on the Salmonella prevalence, the production value or the microbial composition.
