However, in Japan, food irradiation is prohibited except to prevent potato sprouting. 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. The irradiation histories of the eight types of dried plant-based food samples were correctly detected.","PeriodicalId":54373,"journal":{"name":"Food Hygiene and Safety Science","volume":"64 6","pages":"206-213"},"PeriodicalIF":0.3,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139089374","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}

Therefore, we determined the number of Campylobacter in chicken liver. In total, 33 vacuum-packed liver products were obtained from retail stores, and found that 27 of the 33 products (81.8%) were contaminated with Campylobacter. Moreover, Campylobacter was isolated from 138 of 149 livers (92.6%) collected from the 27 Campylobacter-positive products. The mean Campylobacter count was 2.3 log10 CFU/g, while Campylobacter count in 22 of the 138 contaminated livers (15.9%) was >3.0 log10 CFU/g. Furthermore, gastrointestinal tract, liver, and bile samples were collected from 35 broilers at chicken processing plants. We isolated Campylobacter from the gastrointestinal tract of 27 broilers (77.1%). Of these 27 broilers, liver of 24 broilers (88.9%) was Campylobacter-positive, with a mean Campylobacter count of 2.8 log10 CFU/g. Of these 24 broilers, bile of 13 broilers (54.2%) was contaminated with Campylobacter (mean Campylobacter count, 3.5 log10 CFU/mL). Among them, bile of 2 broilers had a Campylobacter count of >8.3 log10 CFU/mL. Collectively, these results indicate that livers derived from broilers colonized with Campylobacter are contaminated with Campylobacter at the time of evisceration. Therefore, to prevent foodborne campylobacteriosis in humans, chicken livers should be thoroughly heated before consumption.","PeriodicalId":54373,"journal":{"name":"Food Hygiene and Safety Science","volume":"64 6","pages":"214-217"},"PeriodicalIF":0.3,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139089377","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}

Analytes were extracted from the samples with acetonitrile and then dehydrated and salted out using magnesium sulfate, trisodium citrate, and sodium chloride. This method was assessed by performing recovery tests of chicken muscle, duck muscle, egg, and raw milk spiked with 20 new target analytes at concentrations of 10 and 100 µg/kg. According to this method, 17 out of 20 target analytes satisfied the guideline criteria in chicken muscle and duck muscle, and all 20 target analytes met the criteria in egg and raw milk. The limit of quantification was less than MRLs for all analytes. Residues were detected in 4 out of 99 samples and analyzed using the validated method, finding that the levels of all residues were lower than the limits of quantification.

Secondary contamination of cooking devices with wheat allergens is a concern if such scrubbing sponges are used to clean other equipment. Therefore, in this study, bowl washing with detergent, using a scrubbing sponge was evaluated as a cleaning method following liquid batter cooking. Multiple trials revealed that wheat allergens were transferred from a bowl coated with 10 g of liquid batter to an unused bowl via sponge scrubbing with a positive rate of approximately 80%. Residual batter was observed in the scrubbing sponge after cleaning and rinsing procedures, with a residual rate of about 20%. Detailed observation of the residue revealed that proteins such as gluten were attached to the cell skeleton, and between the skeletons of the sponge, and starch granules were attached to the proteins. Even with sponge rinsing conditions added to the protocol, complete removal of wheat allergen was difficult. These studies indicate that particular scrubbing sponges for cleaning the residual wheat on cooking utensils should be dedicated exclusively in cooking facilities that prepare allergy-friendly-foods to avoid risk of allergen contamination.","PeriodicalId":54373,"journal":{"name":"Food Hygiene and Safety Science","volume":"26 9 1","pages":"70-78"},"PeriodicalIF":0.3,"publicationDate":"2022-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82550946","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}
