However, extreme class imbalance, where unqualified samples are significantly outnumbered by qualified ones, biases machine learning (ML) models to prioritize majority classes, compromising unqualified sample detection. Conventional oversampling methods fail to handle food inspection data’s nonlinear features, complex distributions, and multiclass scenarios, often generating low-quality synthetic samples and noisy decision boundaries. To address these challenges, we proposed LOF-KNN-CSENN (Local Outlier Factor-K-Nearest Neighbors-Combined Synthetic Minority Over-sampling Technique and Edited Nearest Neighbors), a hybrid sampling algorithm of Synthetic Minority Over-sampling Technique (SMOTE) and Edited Nearest Neighbors (ENN) integrating Local Outlier Factor (LOF) for noise filtering and K-Nearest Neighbors (KNN) for boundary sample preservation. LOF-KNN-CSENN synergizes minority oversampling and majority undersampling to optimize data distribution. A stacking ensemble learning framework is further introduced, combining six tree-based models with Logistic Regression (LR) as a meta model to enhance classification robustness. Experiments on a real-world food safety sampling inspection dataset demonstrated that LOF-KNN-CSENN suppresses noisy sample synthesis and balances data distribution. When integrated with stacking, the model achieves 0.4–5.6% higher precision and 0.8–30.7% higher F1-score compared to single models. Shapley Additive Explanations (SHAP) analysis identified production address, sampling stage, and location as key risk factors, supporting targeted supervision.

Seeds serve as a primary vector for pathogen transmission, with contamination often originating from irrigation water, manure, or cross-contamination during handling. Traditional seed disinfection methods, such as chlorine-based treatments and hydrogen peroxide, have limited efficacy in reducing pathogens while maintaining seed viability. Eugenol has been shown to be an effective foodborne pathogen intervention in a variety of produce types.

The 0.5% eugenol treatment consistently minimized negative impacts on germination rates (p > 0.05) and biomass (p < 0.05), offering the best balance between microbial control and plant health.

The study revealed potential differences in process contaminant dietary exposure patterns between young adults and older demographics, attributable to age-specific dietary preferences and consumption behaviors. Young adults demonstrated significantly higher consumption frequencies of processed meats, deep-fried foods, and packaged snacks compared to older age groups, potentially increasing their exposure to process contaminants such as acrylamide and nitrosamines. Young adults exhibited lower concern levels about dietary chemical hazards and less confidence in making informed food choices, with cost being their primary consideration rather than exposure risk to dietary chemical hazards. While approximately three in four young adults indicated willingness to modify consumption patterns after exposure to information about dietary chemical hazards, one in two young adults acknowledged that other factors would likely take precedence over exposure risk to dietary chemical hazards. Logistic regression analysis revealed that there is a baseline willingness to change consumption patterns after exposure to information on dietary chemical hazards while older age groups and individuals of Indian ethnicity showed significantly higher likelihood of willingness to change consumption patterns.
