Food and food system innovation is a key strategy towards feeding the world in a more sustainable and climate-resilient manner. This paper highlights the use of a science-based risk assessment and management in Singapore’s food safety system, specifically in the integration of exposure assessment approaches to support evidence-based food safety risk analysis and decision-making. The use of complementary top-down and bottom-up exposure assessment approaches through the market monitoring programme, total diet study and human biomonitoring forms a comprehensive integrated exposure assessment strategy which can ultimately inform policy and measures in ensuring and securing a supply of safe food. The discussion on such application for chemical food safety in Singapore offers additional insights into the synergistic inter-relationships contributing to the exposure assessment associated with chemicals in food.</div></div>","PeriodicalId":15903,"journal":{"name":"Journal of food protection","volume":"88 1","pages":"Article 100414"},"PeriodicalIF":2.1,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142693066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we evaluated the effect of four cleaning and sanitation standard operating procedures (SSOPs; T1, T2, T3, T4) on the reduction of total aerobic mesophilic microorganisms, the occurrence of <em>L. monocytogenes,</em> and the microbiota composition in three tree fruit packing facilities (F1, F2, and F3) over two packing seasons (Y1 and Y2). Environmental samples were collected from non-food contact surfaces before and after the application of SSOPs. Total aerobic bacteria were quantified using a standard plate count method, and <em>Listeria</em> spp. and <em>L. monocytogenes</em> concentration was quantified using a Most Probable Number method. Amplicon sequencing was used to determine bacterial and fungal microbiota composition, and Nanopore sequencing was used to detect functional elements in the microbiota that could promote the survival and persistence of <em>L. monocytogenes</em> in the studied environments. The use of SSOPs reduced the total bacterial load by 0.27–2.48 log₁₀ CFU/swab (<em>p</em> ≤ 0.001). Among the treatments tested, the inclusion of a biofilm remover in T4 was most effective in significantly reducing the total <em>Listeria</em> spp. concentration by 1.57–1.27 log₁₀ MPN/swab (<em>p</em> &lt; 0.02) and the frequency of <em>L. monocytogenes,</em> although the latter was not statistically significant. We observed inconsistent changes in the bacterial and fungal microbiota composition due to the application of cleaning and sanitizing SSOPs, which may be due to the presence of dead DNA after the treatment. Using Nanopore sequencing, we detected functional elements related to biofilm formation and stress resistance in the microbiomes of the studied environments. Overall, our study shows that the implementation of SSOPs improved the sanitation outcomes in tree fruit packing facilities. There is a need for the future work to focus on optimizing and validating the standard operating procedures, especially in the areas in which SSOPs were less effective, such as those covered with wax residues.</div></div>","PeriodicalId":15903,"journal":{"name":"Journal of food protection","volume":"88 1","pages":"Article 100436"},"PeriodicalIF":2.1,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142864574","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Factors examined included EC treatment (conventional, untreated), canopy location (high, low), and apple variety (Gala, Golden Delicious). Fruit maturity (mature, immature) was also examined for one year. A rifampicin-resistant generic <em>E. coli</em> cocktail was applied to apples at 7.3 ± 0.4 log CFU/apple, and apples were enumerated for <em>E. coli</em> levels at 0, 2, 10, 18, 34, 42, 58, 82, 106, and 154 h postinoculation.

EC treatment and canopy location did not significantly impact daily linear <em>E. coli</em> die-off rates. Apple variety and maturity demonstrated small but statistically significant impacts on daily linear die-off rates. Nonlinear models (i.e., biphasic and Weibull) best captured <em>E. coli</em> die-off on apples, showing a rapid initial decrease followed by a slower decline over time.

To accomplish this research, data were initially gathered using a custom web crawler technology. These data encompassed various aspects, including user interactions, emotional expressions, and the evolution of topics. Subsequently, the study employed an innovative approach by combining BERT-TextCNN and BERTopic models for a thorough analysis of sentiment and thematic aspects of the textual data. This analysis provided insights into the intricate emotions and primary concerns of the public regarding incidents related to food safety. Furthermore, the research harnessed Gephi, a network analysis tool, to scrutinize the dissemination of information within the network and to monitor dynamic shifts in public opinion. The findings from this study not only shed light on the role of online public sentiment in the propagation of food safety events but also provide fresh perspectives for policymakers and business leaders when responding to similar crises, taking into account the subtleties of online public sentiment.

Compared to the current “trial-and-error” practice, this paper proposes a dedicated two-step classifiability analysis framework to address this issue. The first step collects more than 90 diversified metrics to measure the dataset separability from different perspectives. The second step synthesizes these metrics into a quantitative score using meta-learner and decomposition-based strategies. Finally, two Raman spectroscopic profiling case studies were conducted to validate the method, demonstrating higher scores for the easily separable liquor dataset (around 1.0) compared to the more challenging table salt dataset (&lt;0.5). This score can guide researchers to determine the required model complexity and assess the adequacy of the current physio-chemical profiling instrument.
