This study examined how food safety risk perception, trust in packaging-label information, and food neophilia were associated with consumer engagement with imported packaged foods in Taiwan. An self-administered online survey was completed by 454 adults in Taiwan. The questionnaire assessed perceived food safety hazards, trust in packaging-label information, food neophilia, and imported packaged food purchasing. Descriptive statistics, reliability analysis, bivariate correlations, Friedman tests, a market-entry logistic model, a purchaser-only ordered logistic model, and item-level Mann-Whitney U tests were applied. The highest-rated perceived hazards were unknown ingredients whose safety could not be confirmed, illegal food additives, pesticide residues, natural food toxins, and microbiological contamination. The most trusted package-level label information items were expiry date, ingredient declaration, and disclosure of food additive names. Food safety risk perception was associated with lower odds of market entry, whereas trust in packaging-label information was associated with higher odds of ever having purchased imported packaged foods. Among prior purchasers, food neophilia was associated with higher odds of being in a more frequent purchase category. Item-level comparisons further showed that never-purchasers reported greater concern about all retained food safety risk items, with the largest difference observed for microbiological contamination. These findings suggest that package-level label information functions as a consumer-facing food safety cue, but it should be interpreted as a partial cue rather than as direct evidence of product safety.

Cinnamomum verum, primarily cultivated in Sri Lanka, is regarded as true cinnamon and commands the highest market value due to its rich phenolic and aldehydic composition and low coumarin content. However, when marketed in powdered form, it is frequently adulterated with lower-priced cinnamon species or plant-based fillers to reduce production costs. Such practices constitute food fraud and may introduce allergenic contaminants, thereby posing potential food safety risks. This study proposes a deep learning-based image recognition approach for detecting and characterizing adulteration in cinnamon powder. A total of thirteen convolutional neural network models were trained and evaluated using image data collected from authentic C. verum powder and samples intentionally adulterated with one or two low-cost adulterants at mixing ratios ranging from 5% to 50%. Among the evaluated models, RepVGG demonstrated the most robust performance, achieving Precision and Recall values of 1.0000 in binary classification of authentic cinnamon and an overall Accuracy of 90.34% in multiclass classification across different adulterant types and levels. The proposed system offers a rapid, nondestructive, and low-cost solution for cinnamon powder adulteration screening and shows strong potential for application in food quality control and food fraud risk management.

This retrospective observational study analyzed archived monthly records collected in 2019 and 2020 from one de-identified Taiwanese chilled meat processing facility belonging to a multisite company. Hot pot pork slices were selected as the index product because this item was among the facility's highest-volume and highest-sales products and had complete product, process, hazard-control, microbiological, and operational records. Total plate count (TPC), coliforms, and generic Escherichia coli were evaluated together with operational food protection indicators, including defect rate and shipment-adjusted return outcomes. In the second study year, mean monthly TPC, coliforms, and E. coli values decreased by 13.2, 60.9, and 53.6%, respectively, while shipment volume increased by 15.5%. Defect rate and return-related indicators also declined. Concurrent plant changes included intensified monitoring and verification, broader product-sampling coverage, supplier substitution, split-shift operation, and strengthened hygiene management. These findings support the use of routine plant records for retrospective evaluation of microbiological food quality and operational food protection performance in chilled meat processing SMEs.
