Initial storage phases revealed a shared unspoiled profile across all samples marked by high levels of phenolic VOCs.

Distinct bacterial communities, including genera such as <em>Photobacterium</em>, <em>Aliivibrio</em>, <em>Carnobacterium</em>, and <em>Brochothrix</em>, shaped the production of spoilage-related VOCs. Statistical analyses using the DIABLO framework uncovered strong correlations between bacterial taxa, volatile organic compounds (VOCs), and sensory attributes, emphasizing the distinct spoilage signatures associated with each processing plant.

To address this issue, a Backpropagation Artificial Neural Network (BP-ANN) model incorporating environmental factors was established to predict the growth of <em>L. monocytogenes</em> and background microbiota (BM) in RTE poultry meats—duck wings (DW), duck tongues (DT), and duck necks (DN)—at 4 °C, 10 °C, 15 °C, and 25 °C.

For each PT, ten samples for detection and four samples for enumeration per pathogen were sent to each participant. Over the three years, the PT results demonstrated the ability of the laboratory network to detect L. <em>monocytogenes</em> and <em>Salmonella</em> spp., as well as to enumerate L. <em>monocytogenes</em> and CPS in food matrices. These PTs showcased the robustness of the official laboratory network and provided an opportunity to give scientific and technical advices in case of discrepancy results, representing an efficient tool for quality improvement of the analyses performed by the laboratory network.</div></div>","PeriodicalId":14095,"journal":{"name":"International journal of food microbiology","volume":"438 ","pages":"Article 111218"},"PeriodicalIF":5.0,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143894336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
