Moderne Epidemiologie - Quantitative Methoden in der Tierseuchenbekämpfung

Based on Reg. (EC) No. 2160/2003, programs to control Salmonella in primary production in poultry have been decided and implemented in Europe. This paper addresses the question of the efficacy of these programs to reduce the incidence of salmonellosis in humans in Germany. From the available data it becomes clear, that there is a strong reduction by 54 % of the annual salmonellosis incidence in humans from 2007 to 2010 that is mainly attributable to a reduction in cases of S. Enteritidis (-74 %), but also to a reduction in S. Typhimurium (-30 %). Data from the established control programs and from food surveillance at the same time indicate a reduction of positive herds, of positive samples of poultry meat and of the share of S. Enteritidis and S. Typhimurium among the Salmonella isolates from the positive food samples. Overall, this justifies the assumption that the implementation of the Salmonella control programs in poultry has been successful with respect to the aim of reducing human salmonellosis so far. This is encouraging for the discussion on reduction targets in pig production.
