To explore this low acceptance, this study conceptualized that buyers set food quality and safety requirements that their suppliers must meet to access their markets. These requirements likely influence which audit programs buyers deem acceptable. To date, no study has examined how buyers set these requirements or how such decisions shape their acceptance of GAP audit schemes. Therefore, this study surveyed and interviewed buyers to understand their food safety requirements for various types of produce, suppliers, and operations, as well as how these factors influence their selection of audit programs. The resulting information was used to understand the implications of buyers' food safety requirements for the low acceptance of USDA GAPs audit schemes. The findings revealed that buyers' decisions regarding food safety requirements and audit acceptance are complex, shaped by numerous contextual factors, including regulatory demands, supplier and their operation types, operation scale and location, brand types, retailer reputation, produce risk profiles, and the type, scope, and stringency of audit schemes. The primary factors were the buyers' customers' requirements. Beyond fostering food safety, the requirements were set to strengthen buyers' reputation and competitiveness, enhance quality assurance, and help them capture a share of the produce market. The study concludes by discussing the implications of these findings for expanding acceptance of USDA GAP audit schemes.</p>","PeriodicalId":15903,"journal":{"name":"Journal of food protection","volume":" ","pages":"100620"},"PeriodicalIF":2.8,"publicationDate":"2025-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145058546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, limited research has evaluated the effectiveness of these methods in removing proteins that transfer into frying oil from fried foods. The objective of this study was to assess the efficiency of different filtration methods for removing gluten residues from frying oil. For passive filtration, oil spiked with isolated gluten at a level of 1,000 µg gluten/g oil and oil used for frying 10 batches of breaded shrimp (75 g/batch) were filtered under gravity through metal sieves (pore sizes: 25 µm-2 mm) and cellulose filter papers (pore sizes: 11-25 µm). For active filtration condition selection, gluten-spiked oil (5,000 µg gluten/g oil) was heated (180 °C for 3 min), cooled to 105 °C, and then treated with filter aids - diatomaceous earth (Celite 535) and perlite (Harborlite 900) - at concentrations ranging from 0.05-1%, with mixing times of 5-30 min at 1,000 rpm. Subsequently, the oil was filtered through metal sieves (pore sizes: 0.15, 0.6, and 2 mm). Response surface methodology was employed to identify optimal conditions based on their ability to minimize residual gluten. The optimal condition (0.5% filter aid concentration, 30 min mixing time, and 0.15 mm pore size) was then applied to a total of six filter aids. Under these conditions, passive filtration resulted in over 80% reduction in gluten content of oil while the filtration efficiency of active filtration methods was greater than 99.7%. Removal efficiency varied among the six filter aids, with magnesium silicate and diatomaceous earth-based filter aids demonstrating the best performance. Overall, this study highlighted both passive and active filtration as a promising strategy to significantly minimize gluten cross-contact risks associated with reused frying oil, providing practical guidance for gluten management during frying operations.</p>","PeriodicalId":15903,"journal":{"name":"Journal of food protection","volume":" ","pages":"100618"},"PeriodicalIF":2.8,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145053990","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Soil showed consistently slower inactivation rates than manure across both seasons.

L. monocytogenes was allowed to aggregate on stainless steel, nylon, high-density polyethylene (HDPE), polyvinyl chloride (PVC), and Teflon for 24 h (initial biofilm aggregate) and 96 h (mature biofilms).

All liquid sanitizers significantly reduced L. monocytogenes independently of the surface type (P < 0.05). UV-C treatment application time had no significant effect on biofilm reduction (P > 0.05), though its efficacy on 24 h aggregates varied significantly depending on the surface material. Peracetic acid and lactic acid were the most effective treatment across surfaces, while UV-C alone was the least effective. Combined sanitizer and UV-C light application for up to 5 min did not necessarily improve treatment efficacy compared to sanitizers alone. Confocal images displayed surface cleanability and alterations in microbial architecture before and after treatments.

Results indicated after heat treatment, no statistically significant differences were observed among the packaging materials in terms of cook loss, colour and microbiological shelf-life. However, the PP trays exhibited a higher OTR than PET trays after heat treatment and contact with the chicken. While heat treatment did not affect the thermal properties of either tray, the PP trays showed a shift in crystallization and melting temperature after 28 days of food contact, indicating changes in material properties over time. Sensory analysis revealed lower acceptance scores and more negative sensory attributes for samples in PET trays, possibly due to the suitability and sealing properties of the films for heat treatment.
