Risk factors for Salmonella dublin infection on dairy farms.
In a case-control study of risk factors for Salmonella dublin on 126 dairy farms the following variables were significantly associated with infection. Standardized herd size and water surface area showed a positive association. Contact with cows from other herds during exchange was, unexpectedly, preventive for S. dublin infection. Purchase of cows from other herds was a risk factor. More infections occurred when the feed consisted of grass only compared to grass supplemented with maize or silage. S. dublin infection was highly associated with a liver fluke infection.
