{"title":"Pressure-assisted isolation of micro- and nanoplastics from food of animal origin with special emphasis on seafood","authors":"Julia Süssmann,&nbsp;Elke Walz,&nbsp;Birgit Hetzer,&nbsp;Ralf Greiner,&nbsp;Elke Kerstin Fischer,&nbsp;Sascha Rohn,&nbsp;Jan Fritsche","doi":"10.1007/s00003-025-01543-x","DOIUrl":"10.1007/s00003-025-01543-x","url":null,"abstract":"<div><p>Recent studies have indicated the presence of micro- and nanoplastics in food of animal origin. To address the concerns regarding human dietary plastic uptake, extensive monitoring using validated analytical methods is required. However, a major challenge in analysis lies in the high complexity of preparing food samples rich in macromolecular content (e.g., proteins, complex lipids), such as seafood. Consequently, this study aimed to optimise sample preparation methods for seafood, meat, milk, honey, and eggs, ensuring negligible impact on plastic integrity. Sample matrices were digested using combinations of alkaline, oxidative, and enzymatic approaches, with incubation periods ranging from 6 to 16 h. Particles were rapidly isolated by pressure-assisted filtration, which retained particles in the lower micron range. This method, used for isolating microplastic from food, was compared to the commonly employed vacuum filtration technique. Pressure-assisted filtration improved filtration rates and matrix removal while demonstrating comparable impact on procedural contamination and polymer integrity to vacuum filtration. The feasibility of microplastic analysis was demonstrated using fluorescence imaging. In contrast to microplastics, nanoplastics (&lt; 1 µm) have greater potential for negative biological effects due to their small size, warranting detailed analysis. However, their low particle mass, susceptibility for agglomeration, and the detection limits of conventional spectroscopic techniques pose unique analytical challenges. Addressing these challenges is essential for developing standardised methodologies, including certified food reference material, to enable safety assessments of micro- and nanoplastic in food.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":622,"journal":{"name":"Journal of Consumer Protection and Food Safety","volume":"20 2","pages":"141 - 154"},"PeriodicalIF":1.7,"publicationDate":"2025-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00003-025-01543-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145163356","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although it has been used as a drug since ancient times, severe poisoning or even death may occur in humans and animals when colchicine is ingested in larger amounts. If consumed by food-producing animals, the transfer of colchicine to animal-based food products, as observed with other plant toxins, seems likely, posing a potential health risk to consumers. In the late flowering period of <i>C. autumnale</i>, honey bees may have limited alternatives and may collect its nectar and pollen, potentially transferring colchicine to honey. A literature research on the relevance of colchicine as food contaminant was conducted, followed by experiments to examine its stability in stored honey and milk fermented into yoghurt. The literature review revealed that colchicine is rarely detected as a food contaminant. However, it has been shown to transfer into milk of ruminants following the ingestion of <i>C. autumnale</i>. Experiments with artificially contaminated samples demonstrated, for the first time, the persistence of colchicine in honey stored for 4 weeks under dark conditions and during the fermentation of milk into yoghurt. Although the overall risk to consumers currently appears low, further research is needed to determine whether the continued spread of <i>C. autumnale</i> poses a higher risk to livestock and consumers than previously assumed.</p></div>","PeriodicalId":622,"journal":{"name":"Journal of Consumer Protection and Food Safety","volume":"20 1","pages":"81 - 87"},"PeriodicalIF":1.4,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00003-025-01541-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143465998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Soybean (<i>Glycine max</i>) ranks as the most widely cultivated GM crop globally. With the advancements in site-specific genome-editing tools, the development of GM organisms (GMO) using new genomic techniques has accelerated, particularly in agriculture. In the US, a genome-edited soybean variety, Calyno, was developed with altered fatty acid composition by inactivating two members of the <i>fatty acid desaturase 2</i> (<i>FAD2</i>) gene family, <i>FAD2-1A</i> and <i>FAD2-1B</i>, using TALEN technology. Although deregulated in the US, Calyno soybeans are not authorized for cultivation or import in the European Union and therefore cannot be placed on the European market. To address the need for reliable detection methods in routine analysis for GMO by public authorities, two event-specific qPCR methods were developed to detect the <i>FAD2-1A-Δ63bp</i> and <i>FAD2-1B-Δ23bp</i> gene variants in the Calyno soybeans. In the absence of reference material, methods were validated in-house using synthetic plasmids carrying the target regions’ sequences, following European Network of GMO Laboratories (ENGL) guidelines. Both assays meet the minimum performance requirements for GMO testing, demonstrating high sensitivity, qPCR efficiency, specificity and robustness. An interlaboratory comparison study further confirmed the reliability of these methods. These qPCR assays provide an effective tool for detecting the <i>FAD2-1A-Δ63bp</i> and <i>FAD2-1B-Δ23bp</i> gene variants in Calyno soybeans, supporting GMO testing requirements in the European Union and ensuring accurate monitoring of GM crops.</p></div>","PeriodicalId":622,"journal":{"name":"Journal of Consumer Protection and Food Safety","volume":"20 1","pages":"53 - 62"},"PeriodicalIF":1.4,"publicationDate":"2025-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00003-024-01538-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143465938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review examines 54 scientific studies to identify packaging-related causes of food loss and waste, evaluate whether and how packaging contributes to or mitigates these issues, and propose measures to address them. The findings highlight the need for standardized terminology and methodologies to improve comparability among studies. Key packaging-related issues identified include difficulty emptying, damage and oversized packaging, which could be addressed through improved packaging design and machinery, customized packaging sizes, and consumer education. The packaging design must be adapted to address these key issues and simultaneously consider geographical areas, specific food products and types of packaging. Further research is needed to explore these connections more comprehensively and improve data comparability across methodologies and nomenclature.</p></div>","PeriodicalId":622,"journal":{"name":"Journal of Consumer Protection and Food Safety","volume":"20 1","pages":"5 - 17"},"PeriodicalIF":1.4,"publicationDate":"2025-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00003-024-01539-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143465935","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
