The examinations were carried out on two farms containing altogether 25 000 foxes. Ninety different samples, i.e. 14 feed samples, 16 collective excrement samples and 60 soil samples were examined bacteriologically. Lack of microorganism growth was confirmed in only four soil samples. From the remaining samples bacteria classified to Proteus, Escherichia and Salmonella species were isolated. Salmonella species were found in 29 samples (S. dub- lin - 7 strains, S. enteritidis - 10 strains, S. typhimurium - 12 strains), i.e. seven in feed samples, six in excrement and sixteen in soil samples. Salmonella strains presence in soil material, including the samples from a protected region, points to the bacteria dissemination from animal farms to the natural environment.
