The aim of the study was to analyse Salmonella bacillus infections on poultry farms in the province of Warmia and Mazury, between 2001-2005, taking into account the utilitarian types and species of poultry. Between 2001 and 2005, 11,488 farms from Warmia and Mazury were examined for the presence of Salmonella bacillus. Test results were positive for 10.4% farms. Salmonella bacilli were most often isolated from meat poultry and flocks of ducks in particular. Additionally, the presence of two salmonella serotypes was established: Salmonella enteritidis and Salmonella typhimurium. Salmonella typhimurium bacilli were isolated from all groups of poultry, with the exception of laying hens and breeding geese and hens. Salmonella enteritidis was most often found in meat poultry and laying hens, and not in ducks and geese. A large percentage of infected samples revealed Salmonella bacilli which were not precisely classified and described. Most cases of unidentified salmonella types were recorded in 2002, while in subsequent years a clear downward trend was observed (with the exception of geese farms).
