We investigated the relationship between Campylobacter counts in cecal contents of broilers and those in chicken meat at eight chicken processing plants. Ceca and their breast products derived from broilers from 51 flocks were collected. Campylobacter were isolated from cecal contents of 40 (78.4%) flocks. The average number of Campylobacter in the ceca of the Campylobacter-positive flocks was 7.6 1og10 CFU/g. Of 51 chicken breast products, 35 (68.6%) were contaminated with Campylobacter and the average number of Campylobacter was 1.7 1og10 CFU/g. All the Campylobacter-positive products were derived from Campylobacter-positive flocks. The results of this study indicate that there is a weak positive correlation (R=0.37) between the number of Campylobacter in the ceca of broiler flocks and the number of Campylobacter in chicken meat. Of the 14 products with C. jejuni/C. coli counts of 2.0 log10 CFU/g or more, nine (64.2%) were from groups with high Campylobacter (≥ 8.4 log10 CFU/g) in the ceca. The Campylobacter prevalence of products from chicken flocks with C. jejuni/C. coli counts of 6.2 log10 CFU/g or less in the cecal contents have a C. jejuni/C coli contamination rate of 50% (3/6) with a maximum Campylobacter count of 1.4 log10 CFU/g.","PeriodicalId":54373,"journal":{"name":"Food Hygiene and Safety Science","volume":"66 4","pages":"61-67"},"PeriodicalIF":0.2,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145453085","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}

The measurement conditions and extraction and trypsin digestion process for protein pretreatment were optimized. A sample spiked with each allergen was analyzed to evaluate the performance of the analytical method, including the extraction process. Repeatability and intralaboratory precision met the target values for all allergens, confirming the stability of the analytical method. Furthermore, the S/N ratio, retention time, and peptide ratio demonstrated the usefulness of the method as a qualitative test. Moreover, for milk and egg allergens, the equivalence of the quantitative values calculated using the developed method to those of ELISA was confirmed; however, this equivalence could not be confirmed for commercially available processed foods and some quality control samples. For buckwheat and peanut allergens, the equivalence of the quantitative values to those of ELISA could not be confirmed in the spiked sample. These findings demonstrate that this analytical method is useful as a rapid and simple qualitative test. It is also an excellent alternative to ELISA as it produces less waste and reduces environmental burden.","PeriodicalId":54373,"journal":{"name":"Food Hygiene and Safety Science","volume":"66 4","pages":"74-79"},"PeriodicalIF":0.2,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145453281","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}

The least square method is allowed to apply only under the condition that the measurements follow the normal distribution with a constant variance. Actually, however, it is thought that as the measurements of samples are higher, the scattering of the measurements would be also larger. In this study, thus, the effect of the scattering of measured values of samples on the concentration estimation was studied with two normal distribution models with a constant variance and a variance changing to measured values. Measurement data analyzed here were random samples from the normal distributions with various variance. As a result, in the case that the concentrations of the target substance and the measurements were linear, the latter model with the changing variance was statistically more appropriate for the data whose scattering increased with it. However, no remarkable differences were observed between the two models in the standard curves and the estimates from those curves for the measurement sets studied. In the case that the concentrations and the measurements were nonlinear being concave downward and upward, the same results were also observed. These results showed that the model with the changing variance would be more appropriate than the one with the constant variance for various measurement data, while both models could also successfully estimate the concentration of unknown samples.","PeriodicalId":54373,"journal":{"name":"Food Hygiene and Safety Science","volume":"66 5","pages":"112-117"},"PeriodicalIF":0.2,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145453544","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}

MWs are varying in the degree of hardness and carbonation. The results of two carbonated MWs obtained through the validated official method for cyanide analysis in tap water did not meet the criteria of the validation guideline for MW in Japan. Furthermore, in the pH adjustment during pretreatment, some MWs did not reach approximately pH 2.4, the level assumed in tap water quality tests. After five-fold dilution of the samples with phosphate buffer, the specified pH value of 2.4 was achieved, leading to the improvements in trueness. The validation tests of the method with the additional dilution step showed the trueness from 93.0 to 103.8%, RSDs of repeatability and within-laboratory reproducibility below 3.83% and 4.68%, respectively. These values fulfill the criteria on both analytes. The developed method indicated the potential applicability for accurate determination of cyanide ion and cyanogen chloride in a range of commercially available MW products.","PeriodicalId":54373,"journal":{"name":"Food Hygiene and Safety Science","volume":"66 3","pages":"46-50"},"PeriodicalIF":0.2,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144978971","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}

This method involves the hydrolysis of conjugates by ß-glucuronidase/aryl sulfatase, clean-up with an immunoaffinity cartridge, and analysis using LC-MS/MS. The developed method was evaluated for zeranol, taleranol, zearalanone, and zearalenone in bovine urine at concentrations of 1 and 2 μg/L. The trueness ranged from 92 to 101%, with intra-day precision of <9% and inter-day precision of <13%. No interfering peaks were observed in the chromatogram near the analyte retention times. This analytical method is valuable for monitoring taleranol, zearalanone, and zearalenone in beef exports to the European Union. The proposed method is also applicable for screening whether zeranol was illegally administered or ingested via feed contaminated with Fusarium toxins, particularly in cases in which taleranol was detected.","PeriodicalId":54373,"journal":{"name":"Food Hygiene and Safety Science","volume":"66 2","pages":"32-38"},"PeriodicalIF":0.2,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144200852","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}
