Recently, lithium chloride (LiCl) was described to be effective against varroosis, a parasitic disease leading to loss of honey bee colonies with limited therapy options. However, LiCl treatment is not currently authorized for use in honey bee colonies. Such treatment might result in elevated lithium amounts in honey. To address this, a robust method for quantifying lithium in honey was validated using a microwave-assisted digestion technique combined with Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES), achieving detection levels as low as 0.151 mg/kg. The method was applied to 65 commercially available, randomly chosen honey samples, all of which had lithium levels below the limit of quantitation (LOQ). Furthermore, the method was successfully adapted for use with more complex bee matrices, including royal jelly, bee bread, propolis, and whole bees.</p></div>","PeriodicalId":622,"journal":{"name":"Journal of Consumer Protection and Food Safety","volume":"19 4","pages":"455 - 460"},"PeriodicalIF":1.4,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00003-024-01527-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142266077","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}

To meet increasing regulatory requirements for a growing number of GM soybean events, high-throughput and cost-effective detection methods are indispensable. In this study, 14 widely commercialized GM soybean events, including GTS40-3-2, MON89788, CV127, A2704-12, A5547-127, 305423, 356043, MON87701, MON87705, MON87708, MON87769, SYHT0H2, FG72, and DAS-444Ø6-6 were utilized as targets for event-specific identification. A high-throughput detection method was established by integrating a single universal primer multiplex PCR (SUP-M-PCR) with capillary electrophoresis technique. This method enables the identification of 14 soybean events in a single PCR reaction, addressing the limitations of conventional multiplex PCR such as self-inhibition and amplification variations between different primers. Furthermore, it significantly enhances the sensitivity and accuracy of previous multiple detection methods, achieving a detection sensitivity of 0.05% (w/w). Overall, this approach greatly improves detection efficiency and holds promising potential for the identification and detection of 14 types of GM soybean events and their derivatives.</p></div>","PeriodicalId":622,"journal":{"name":"Journal of Consumer Protection and Food Safety","volume":"19 4","pages":"445 - 454"},"PeriodicalIF":1.4,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142187421","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}

Due to their potential carcinogenicity, residual levels in food are a target of consumer protection. Assessment of compliance of paper food contact articles regarding chloropropanols is commonly done using cold water extraction according to EN 645. However, this gives limited information on actual consumer exposure. To support risk assessment, migration of chloropropanols from paper straws into food simulants was compared to cold water extraction. Established methods using silylation with MSTFA and GC-MS/MS were adapted for food simulants B and D1. While absolute concentrations were higher in cold water extracts, released amounts were similar when accounting for sample weight and simulant volume. For uncoated paper under foreseeable use conditions, cold water extraction results can estimate exposure. Paper straws compliant with BfR recommendation XXXVI limits do not considerably contribute to total 3-MCPD intake. Thus, enforcing these limits is suitable to protect consumers from harmful chloropropanol exposure from food contact materials.</p></div>","PeriodicalId":622,"journal":{"name":"Journal of Consumer Protection and Food Safety","volume":"19 4","pages":"377 - 381"},"PeriodicalIF":1.4,"publicationDate":"2024-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142187422","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}

Efforts to overcome this polarization generally involve distributing information, but research indicates that information has little to no impact on GE attitudes, especially among those with extreme positions. Recent studies suggest that moral value concerns drive GE opposition. However, the specific moral values underlying both support and opposition for GE are unknown, as is whether these values differ between GE supporters and opponents. The present research addresses these questions through latent content analysis. Findings show that most arguments in the debate address moral value concerns related to loyalty, often focusing on trust issues. Trust issues are more prevalent than moral concerns about preventing harm and risks. Furthermore, moral value conflicts are likely since GE supporters emphasize concerns related to authority, fairness, and liberty, while GE opponents focus more on values related to care and purity. This paper discusses these findings and recommends steps for improved science communication.</p></div>","PeriodicalId":622,"journal":{"name":"Journal of Consumer Protection and Food Safety","volume":"19 4","pages":"437 - 443"},"PeriodicalIF":1.4,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141866853","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}
