| Abstract: | In 2003, a feed-borne outbreak of Salmonella Cubana occurred in Sweden as a result of contamination in a feed plant. Salmonella
Cubana was detected in 49 out of 77 pig farms having received possibly contaminated feed. In this study, potential risk factors
for farms being salmonella positive were examined, and a survival analysis was performed to investigate risk factors affecting
the restriction period for salmonella positive farms. |
