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
In an interlaboratory study on the prevalence of Salmonellae in German slaughter pigs a comparison of the traditional bacteriological and the serological technique used in the Danish Salmonella control programme was included. In total, about 12000 animals were investigated using both techniques. Samples were collected from February through June 1996. Seven slaughterhouses distributed over the whole country participated on a voluntary basis. A total of 11,942 animals delivered in 752 lots at ten occasions to the participating slaughterhouses were investigated. The lots often comprised pigs from individual finishing farms. From each lot, a maximum of 50 animals were sampled. A faecal swab, a mesenteric lymph node and a meat sample were collected from each carcass. The results of the microbiological analysis of faeces and lymph nodes of each animal were described in separate presentations.
