abstract = "This study illustrates how prevalence and incidence of Salmonella Dublin in cattle has been markedly reduced in dairy herds during active surveillance and a control programme targeting infected herds in Denmark from 2002 to 2010. The results suggest that this might by a good alternative to passive surveillance systems. Register data might be useful for design of effective surveillance programmes for Salmonella Dublin in cattle in the future. Statistical analysis of register-based variables confirmed previously known risk factors for becoming test-positive (i.e. purchase of animals from test-positive herds, number of cattle in test-positive neighbouring herds, herd size and season), but also pointed out additional factors affecting the risk of dairy herds changing status from test-negative to test-positive (indicative of new or recurrent infection). Increasing geometric cell count measured through the mandatory milk quality assurance scheme was associated with increasing risk of becoming test-positive, while participation in a voluntary control programme for paratuberculosis, another bacterial infection with similar transmission patterns, was associated with decreased risk of becoming test-positive. This suggests that there might be synergistic benefits from running control programmes for both infections simultaneously. We did not find the risk of becoming test-positive significantly different between organic and conventional herds, nor between analysing laboratories. Even when controlling for other risk factors, it was evident that the risk of changing to test-positive was significantly lower after the surveillance programme was supplemented by an intensified control period from October 2007 and onwards than during the surveillance period before 2007.",
