This helps to prevent the use of nonprescribed species, which might cause unexpected or unintended health hazards. However, there are cases in which the names of the source species listed in the official specifications differ from the accepted scientific names based on the latest taxonomic research. In this paper, we argue that it is more important to define scientific and Japanese names with an emphasis on traceability in order to control the range of food additive ingredients in a rational and sustainable manner. Therefore, we proposed a method for ensuring traceability as well as a specific notation procedure for scientific and Japanese names. Using this method, we examined the source species for three food additives. In some cases, the range of sources species expanded with the change in scientific names. Ensuring traceability is extremely important, but it is also necessary to confirm whether unexpected species are included when names are changed.","PeriodicalId":54373,"journal":{"name":"Food Hygiene and Safety Science","volume":"64 2","pages":"78-88"},"PeriodicalIF":0.3,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9503176","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}

In this study, we investigated whether current Japanese official qualitative and quantitative methods (the current official methods) for GM maize can comprehensively target events in domestically distributed maize. For samples with the identity-preserved (IP) handling system and non-IP samples from the United States (US) and non-IP samples from Brazil, we performed event-specific real-time PCR targeting 25 authorized single GM maize events in addition to the current official methods. According to our results, 15 events targeted by the current official methods were detected, but insect-resistance (IR) Event5307 and herbicide-tolerant (HT) DAS40278, not targeted by the current official methods, were detected in the US (one out of 5 lots) and Brazilian (four out of 5 lots) non-IP samples, respectively. Nevertheless, a survey of recent GM maize acreage in recent years has revealed that more than 95% of the acreage in US maize is occupied by HT or IR/HT stacked events, and that more than 95% of the acreage in Brazilian maize is occupied by IR or IR/HT stacked events. Because the current official methods can target all stacked events related to Event5307 and DAS40278, the only undetectable events are the single Event5307 and DAS40278, whose production is estimated to be less than 5% of the total production in the producing country. Therefore, we conclude that the current official methods for the labelling of GM maize should be maintained in view of practicability.","PeriodicalId":54373,"journal":{"name":"Food Hygiene and Safety Science","volume":"64 6","pages":"218-225"},"PeriodicalIF":0.2,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139089375","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}

There are many reports on the prevalence and antimicrobial resistance of Campylobacter and Salmonella in broiler meat, but few in spent hen meat. Therefore, we investigated the prevalence and antimicrobial resistance of these genera in spent hen meat collected at chicken processing plants. Campylobacter and Salmonella were isolated from 47 (92.2%) and 18 (35.5%), respectively, of breast meat derived from 51 spent hen flocks. Campylobacter jejuni accounted for 87.5% of Campylobacter isolates. The highest resistant rate in C. jejuni isolates was found for ampicillin (45.3%), followed by tetracycline (14.3%) and ciprofloxacin (14.3%). There was no Campylobacter isolate resistant to erythromycin, which is recommended as a first-choice antimicrobial for humans when Campylobacter enteritis is strongly suspected. Of Salmonella isolates, the first and second most frequent serovars were Salmonella Corvallis (30.4%) and S. Braenderup (21.7%), respectively. Of Salmonella isolates, 30.4% were resistant to streptomycin. There was no Salmonella isolate resistant to ciprofloxacin, which is one of the recommended antimicrobials for humans against Salmonella enteritis. This study shows that one third of spent hen meat is contaminated with Campylobacter or Salmonella, and administration of erythromycin or cefotaxime is an effective option for patients with Campylobacter- or Salmonella- enteritis, respectively, caused by consumption of spent hen meat.","PeriodicalId":54373,"journal":{"name":"Food Hygiene and Safety Science","volume":"64 4","pages":"117-122"},"PeriodicalIF":0.3,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10180843","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}

Herein, 5,6-dihydrothymidine (DHdThd) residue-a damaged nucleoside generated from the thymidine (dThd) residue in DNA contained in food upon irradiation-was used as a detection indicator. Eight dried plant-based food samples were gamma ray-irradiated in the range from 3.2 to 8.3 kGy. Subsequently, DNA was extracted from the irradiated sample and digested into nucleosides by the three enzymes, and the test solution was analyzed by liquid chromatography tandem mass spectrometry (LC-MS/MS). Evidently, in all samples, the concentration ratio of DHdThd to dThd in the test solution (DHdThd/dThd) was dependent on the irradiation dose; moreover, during storage under frozen conditions for at least 890 d post-irradiation, this concentration ratio was equal to that immediately after irradiation.

However, this method has several operational issues, such as the formation of emulsion during liquid-liquid partitioning. Additionally, impurities present in the reagents (sodium sulfate decahydrate or anhydrous sodium sulfate) used to prepare saturated sodium sulfate solution can degrade pheophorbide and other related compounds, resulting in a significant decrease in analytical values. In this study, we thoroughly examined each step of the official method to enhance the operability and develop an alternative method that eliminates the need for saturated sodium sulfate solution. The developed method was evaluated for pheophorbide a and pyropheophorbide a at 100 mg%. Satisfactory analytical performance was achieved with trueness of 100% for pheophorbide a and 90% for pyropheophorbide a, and relative standard deviations of intra- and inter-day precision below 5% for both compounds.

Moreover, Campylobacter was isolated from 138 of 149 livers (92.6%) collected from the 27 Campylobacter-positive products.
