Listeria monocytogenes is a foodborne pathogen responsible for listeriosis. The inhibitory effect of essential oils (1% v/w) of Thymus daenensis Celak (Lamiaceae), Thymbra spicata L. (Lamiaceae) and Satureja bachtiarica Bunge (Lamiaceae) applied to the surface of chicken frankfurters was determined on L. monocytogenes inoculated at low (103 CFU/g) and high (106 CFU/g) populations and stored for seven and 14 days. The results showed that L. monocytogenes populations increased during seven and 14 days of storage at 4 °C on control frankfurters without essential oil. The application of 1 % essential oil (v/w) of herbs to frankfurter surfaces can significantly reduce (p<0.05) the L. monocytogenes populations as compared to control in two inocula treatments after seven and 14 days of storage at 4 °C. Listeria monocytogenes je povzročitelj listerioze, ki se pojavlja v živilih. Proučevan je bil inhibitorni učinek eteričnih olj (1% v/w) zelišč Thymus daenensis Celak (Lamiaceae), Thymbra spicata L. (Lamiaceae) in Satureja bachtiarica Bunge (Lamiaceae), nanešenih na površino piščančjih hrenovk, ki so bile inokulirane z nizko (103 CFU/g) oziroma visoko populacijo (106 CFU/g) listerije ter shranjene za 7 oziroma 14 dni. Rezultati so pokazali, da se populacije L. monocytogenes povečajo tekom 7 oziroma 14 dni shranjevanja pri 4 °C na primerjalnih hrenovkah. Uporaba 1 % (v/w) eteričnih olj zelišč pri hrenovkah lahko značilno (p<0.05) zmanjša populacijo L. monocytogenes v primerjavi s kontrolo.
