Prevalence of intestinal parasites and Salmonella in the feces of farm-bred foxes and mink in Lublin Voivodeship as a potential risk in agricultural use
The aim of the study to evaluate the occurrence of intestinal parasites and Salmonella bacteria in fox and mink faeces and to assess potential biological risk related to their use as a natural fertilizer in agriculture. The study included 12 randomly selected fox-breeding farms with a total population of 2800 animals and 9 mink farms with a total of 24650 animals. The material examined comprised 120 samples of fox faeces and 66 samples of mink faeces. In addition, the intestines of 45 foxes from 3 farms were examined by the SCT method. The samples of feces and intestines of slaughtered foxes were examined parasitologically and bacteriologically. In 13 samples of fox faeces, the presence of parasites of the genus Isospora was observed, whereas 2 samples contained the eggs of nematodes of the alimentary tract of Toxocara canis and Strongyloides spp. The examination of the intestines confirmed the presence of mature forms of Toxocara canis in 2 foxes. In mink, only parasites of the genus Isospora were found. The presence of pathogenic bacteria was noted in the faeces of foxes. In 5 samples of fox faeces, Salmonella bacteria were found. No Salmonella bacteria were isolated in mink faeces. The present study confirmed a considerable decrease in the extensiveness of Toxocara spp. invasion in foxes bred on farms in Lublin Voivodeship. At the same time, it was confirmed that farm-raised foxes, unlike mink, are not entirely free of intestinal parasites and Salmonella bacteria, which highlights the need for continued monitoring.
