This study aimed to investigate the antilisterial effectiveness of post-process antimicrobial treatments employing olive mill wastewater polyphenolic extract (PE) in commercially manufactured frankfurters. Frankfurters were inoculated on the surface with a three-strain LM mixture (~102 CFU\/g), treated on the surface with PE in a 2-fold series of concentrations (PM, 2PM, 4PM) and a control group (CTR) of PE-untreated samples. Then, the frankfurters were vacuum-packed and stored at 4 \u00b0C for 28 days. Samples were examined on days 0, 7, 14, 21, and 28 for LM count, in silico growth modeling, and impacts on pH, water activity (aw), and sensory characteristics. From T(time) 7, the PE treatment showed a significant effect on LM growth, registering maximum \u0394 values between CTR and 4PM of 3.19, 4.86, 4.59, 4.39 at T7, T14, T21, T28, respectively. Minimum effect was attributable to PM treatment with \u0394 values (CTR versus PM) of 2.07, 2.52, 1.14, 0.65 at T7, T14, T21, T28, respectively. No significant changes occurred in pH (average 6 at T0 and 5.9 at T28), aw (average 0.978 at T0 and 0.968 at T28), nor in sensory profile (p &gt; 0.05). These findings suggest that PE is an effective natural antimicrobial, offering a promising approach to enhancing food safety and extending shelf life in meat products.<\/jats:p>","DOI":"10.3390\/foods14050774","type":"journal-article","created":{"date-parts":[[2025,2,25]],"date-time":"2025-02-25T07:45:08Z","timestamp":1740469508000},"page":"774","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Control of Listeria monocytogenes on Frankfurters by Surface Treatment with Olive Mill Wastewater Polyphenolic Extract"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6998-0348","authenticated-orcid":false,"given":"Rossana","family":"Roila","sequence":"first","affiliation":[{"name":"Department of Veterinary Medicine, University of Perugia, Via San Costanzo 4, 06121 Perugia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrea","family":"Valiani","sequence":"additional","affiliation":[{"name":"Istituto Zooprofilattico Sperimentale dell\u2019 Umbria e delle Marche \u201cTogo Rosati\u201d, Via Salvemini 1, 06126 Perugia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8726-2075","authenticated-orcid":false,"given":"Maurizio","family":"Servili","sequence":"additional","affiliation":[{"name":"Department of Agricultural, Food and Environmental Sciences, University of Perugia, Via S.
