The tilmicosin concentrations in liver, kidney, muscle, and skin/fat of TBSFs collected from different time points (0.16, 1, 3, 5, 7, 9, 12, 20, 30, 40 days after last administration) were determined by UPLC-MS/MS. The results indicated that the tilmicosin concentrations in TBSFs tissues varied significantly, and kidney had the highest average concentrations (2604.65 ± 4625.20 μg/kg), followed by liver (1125.54 ± 1479.24 μg/kg), skin/fat (372.81 ± 428.33 μg/kg), and muscle (104.52 ± 143.95 μg/kg). Meanwhile, tilmicosin was still detected in all the four studied tissues (liver, kidney, skin/fat, and muscle) of TBSFs at the last time point (40th day after administration), suggesting that tilmicosin in TBSFs depleted slowly. Based on our experiments, the recommended withdrawal time of tilmicosin for TBSFs after oral administration for three consecutive days at a dose of 75 mg/L in water should be 32 days, which is much longer than the duration specified by Chinese regulatory authorities (10 days), and the abundance of melanin in TBSFs might be responsible for this phenomenon. Hence, a special use and withdrawal procedure of veterinary drugs in TBSFs is needed, and it is essential to focus on potential involvement of melanin in tilmicosin accumulation.","PeriodicalId":12295,"journal":{"name":"Food Additives and Contaminants Part A-chemistry Analysis Control Exposure & Risk Assessment","volume":"42 2","pages":"203-212"},"PeriodicalIF":2.3,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143046113","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The green beans, Arabica and Robusta, exhibited glyphosate levels above the EU-MRL (0.14-0.21 mg/kg), representing a worst-case scenario. The beans were roasted to different degrees and subsequently used for different coffee preparations. As a result of roasting (>200 °C), glyphosate contents were reduced, frequently by more than 73%. Remarkably, up to 9% of initial glyphosate was removed together with the silverskin, already at lower temperatures. Filtered and instant coffee beverages prepared from respective coffee samples resulted in virtually quantitative glyphosate transfer. Glyphosate transfer was significantly less for espresso, and ristretto, apparently due to the reduced amounts of water used for extraction. Aminomethylphosphonic acid (AMPA) was not detectable on any process level, confirming that AMPA is not a thermal glyphosate degradation product. In conclusion, compelling evidence is provided that glyphosate contamination becomes considerably reduced during roasting, whereas beverage preparation contributes at best to a minor further reduction. In consequence, even unusually high initial glyphosate loads in green beans are strongly reduced by the roasting process, resulting in a final cup content of <0.4 µg.","PeriodicalId":12295,"journal":{"name":"Food Additives and Contaminants Part A-chemistry Analysis Control Exposure & Risk Assessment","volume":" ","pages":"59-74"},"PeriodicalIF":2.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142647262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From 2020 to 2021, a field study was conducted with 70 sheep grazing on a pasture (stocking density of 12 sheep/hectare) with considerable quantities of tansy ragwort. After slaughter, blood samples were taken for analysis of liver enzyme activities and haemoglobin concentration. Samples of ruminal fluid, liver and diaphragm pillar were analysed for PAs. The amount of ingested ragwort was determined by counting missing plant parts and calculating their weight using reference material. The mean daily intake of ragwort per sheep ranged from 0.16 kg to 4.89 kg fresh matter and corresponded to PA doses from 0.3 to 40.9 mg/kg body weight with no effect on the liver enzyme activities. The PA concentrations in the animal tissue were between the limit of detection and a maximum of 8.0 µg/kg in the liver and 2.5 µg/kg in muscle.

This study aimed to evaluate the effect of carvacrol (unencapsulated and loaded into Eudragit® and chia nanocapsules) on the growth of Aspergillus species. Spore germination and mycelial growth of Aspergillus spp. were evaluated using the agar dilution culture method. The stability of nanocapsules during storage was monitored monthly by evaluating the particle size distribution, polydispersity index, and zeta potential. Antifungal and antitoxigenic effectiveness of nanocapsules were assessed by counting fungal colony-forming units and determining mycotoxin levels in grapes. A dose-dependent effect of carvacrol (unencapsulated and encapsulated forms) on spore germination and mycelial growth was observed. During 180 days of storage, carvacrol into Eudragit® nanocapsules preserved their nanometric dimensions, whereas chia nanocapsules maintained this characteristic for 30 days. The antifungal effectiveness of both encapsulated forms persisted for 210 days. No mycotoxin was found, even when fungal growth was not completely suppressed.

Food contact substances (FCS) containing polyfluorinated long-chains (≥C8) were voluntarily removed by their manufacturers from the U.S. market in 2011 due to health concerns and largely replaced with FCSs containing short-chain (≤C7) PFAS. In 2020, FDA findings of potential biopersistence of 6:2 FTOH (CF3(CF2)5CH2CH2OH) similarly prompted an additional voluntarily phase-out of FCSs containing 6:2 FTOH by their manufacturers that was completed by the end of 2023. To monitor the phase-out process, a screening method was developed to detect FCPs containing ester-linked polyfluorinated pendant chains. Direct Analysis in Real Time-Isotope Dilution-High Resolution Mass Spectrometry (DART-ID-HRMS) enabled rapid semi-quantitative detection of 6:2 FTOH in FCP saponification reaction headspace without requiring sample concentration or chromatography. 19F-NMR analysis confirmed 6:2 FTOH pendant chain identity and detection dependence on saponification. The speed and specificity of this approach arise from ester saponification in the presence of stable isotopically labeled 6:2 FTOH; high FTOH differential volatility relative to nonfluorinated matrix, and the facile production of FTOH gas-phase anions (e.g., [M + O2]·-, [M-H + CO2]-) under ambient ionization conditions.

Analyses demonstrated that distributions of contaminants and residues within a particular consignment differed, and that distributions of a particular contaminant or residue differed among consignments.

Pairwise correlations were evaluated using two statistical approaches adapted to censored data: (i) non-parametric Kendall's tau and (ii) parametric Bayesian modelling. Nonparametric and parametric correlation analyses showed similar results. We found positive correlations among one or more pairs of the TEs (As, Pb, and Cd) in 9 of the 10 categories of foods intended for infants and young children and a negative correlation for one TE pair for a single food category. Where positive correlations are observed, removing samples with high concentrations of a given TE reduces the mean of the other TEs in that food. We also explored the impact of correlations among TEs on the fraction of the supply below maximum levels. Positive correlations among TEs have the potential to reduce the impact on the supply when setting multiple maximum levels.","PeriodicalId":12295,"journal":{"name":"Food Additives and Contaminants Part A-chemistry Analysis Control Exposure & Risk Assessment","volume":" ","pages":"22-39"},"PeriodicalIF":2.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142461581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
