The present research was carried out to investigate the prevalence of Listeria in 190 samples of duck breast and liver, obtained from three lots of ducks during gavaging - age of 79 days and then, after slaughter processing and vacuum packing - age of 86 days. Seventeen feed samples were also studied. Data showed that contamination with Listeria spp. of gavaged ducks was 6.84% - 13 specimens and of feeds – 17.6% - 3 samples. Positive swabs after slaughtering of ducks were 6 - 4.3% and those after vacuum-packing 9 - 6.4%. L. monocytogenes was found in 2.9% of all experimental specimens. The dominant serological group of Listeria spp. was II with 12 isolates followed by group I with 2 isolates.
