AB Since the first detection of bovine spongiform encephalopathy (BSE) in homebred cattle in Germany on 26 November 2000, 382 cases have been confirmed until 30 September 2005. Thirty-two of these cases were reported from the Federal State of Schleswig-Holstein (SH). There are hypotheses on the routes of infection for German cattle, but only few efforts have been made to assess potential risk factors by epidemiological studies. The purpose of this study was to identify potential risk factors at the farm level for the occurrence of BSE in cattle in SH. By applying the method of indirect standardization, the prevalence of various structural and management parameters of BSE-affected farms in SH was compared with the prevalence of these parameters in a standard population of cattle farms from SH. The data describing the standard population were obtained by a cross-sectional study performed in SH in 2003. Data of the BSE case population were available from the central German BSE case database. A possible association of the occurrence of BSE with the feeding of milk replacers to calves was observed. There was a clear indication that the occurrence of BSE was associated with the presence of pigs and/or poultry on the farm. This finding suggests that cross-contamination of feed or cross-exposition may have occurred in SH. The results obtained using the indirect standardization analysis were validated by multiple logistic regression. This study indicates that the feedborne path has been the principal route of transmission for the BSE agent in SH.
IN Mit der Methode der indirekten Standardisierung glauben die Autoren einen möglichen Zusammenhang zwischen BSE-Fällen in Schleswig-Holstein und der Verfütterung von Milchaustauschern gefunden zu haben. Einen eindeutigen statistischen Zusammenhang sehen Pottgießer et al. zwischen BSE und der gemeinsamen Haltung von Rindern, Schweinen und Geflügel auf einem Bauernhof. Sie sehen darin einen Hinweis auf versehentliche oder absichtliche Fütterung von Rindern mit tiermehlhaltigem Futter für Schweine oder Geflügel.
