A nationwide online survey was conducted with 73,010 supplement users from the previous year. Of these, 221 individuals with worsening clinical test values responded to the full-scale survey. To compare surveys with different outcome indices, we used previously reported data from similar surveys.Only 0.5% of individuals who self-reported worsening of clinical test values caused by supplement use recognized an almost certain causal relationship. Among the test items, blood lipids were the most frequently reported. The frequency of worsening liver function markers was 0.2% in supplement users. Among those who experienced worsening clinical test values, 56.1% received no treatment and 82.4% did not report the incidence of worsening clinical test values anywhere. The ingredient-based classification of products revealed more \"Peptides or animal by-products\" and \"Combination products/not classifiable products\" than those associated with other categories. Compared to the results of the survey about the experience of diarrhea or skin manifestations, those who experienced worsening clinical test values were predominantly men, frequent and long-term users, and individuals whose products could not be identified.Few supplement users experience worsening of liver function markers, which does not seem serious. However, it is difficult for supplement users to recognize abnormal changes by themselves. Thus, it is important to record product information, usage, and changes in physical condition.","PeriodicalId":54373,"journal":{"name":"Food Hygiene and Safety Science","volume":"63 5","pages":"169-176"},"PeriodicalIF":0.3,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40663537","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}

Here, we determined TTX levels in leftover foods and serum and urine samples from eight food poisoning incidents associated with TTX contamination in Nagasaki, Japan, from 2011 to 2017.Seven food samples associated with four of these food poisoning incidents were classified as weakly toxic (four samples), moderate-to-strongly toxic (two samples), and strongly toxic (one sample).In comparison with previous reports, TTX was detected at harmful levels in the urine samples, but the grade of poisoning symptoms varied.The patients' time to maximum serum TTX levels (Tmax) was estimated to be 12-24 h after ingestion of TTX-containing foods. Additionally, serum TTX levels of 19.5 ng/mL or higher within 24 h after ingestion indicated Grade 3 poisoning associated with respiratory abnormalities.These conditions were considered indicators of severe symptoms, while TTX levels of 1-3 ng/mL relate to the onset and disappearance of symptoms. A negative correlation was found between the logarithm of serum TTX concentration and the time after ingestion for two patients, indicating that the TTX serum levels decreased logarithmically. Furthermore, the TTX serum half-lives (T1/2) were 17.5 and 23.7 h.The results of this study enhance our understanding of TTX food safety and contribute to TTX risk assessment.","PeriodicalId":54373,"journal":{"name":"Food Hygiene and Safety Science","volume":"63 5","pages":"182-189"},"PeriodicalIF":0.3,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40663539","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}

However, associated histamine food poisoning demands microbiological controls. Furthermore, studies reported that histamine production by histamine-producing bacteria is affected by temperature. Therefore, to prevent histamine food poisoning, it is desirable to store foods below 4℃. However, it is challenging to maintain the storage temperature of food substances in refrigerators constantly below 4℃. Thus, we investigated histamine production capacity using seven histamine-producing bacterial strains under storage at 10℃, a more reasonable cold storage condition. Subsequently, we examined the variation of histamine production in buffers, the correlation between bacterial density and histamine production quantities, and the growth rate in broths. Results showed that similar levels of histamine were produced in buffers even after 5 days of storage under certain conditions in which histamine-producing bacteria did not grow. Moreover, bacterial density was proportional to histamine production, and the coefficient of determination was more than 0.97, and the bacterial density required to produce 200 μg/mL of histamine during storage at 10℃ was calculated to be 4×107-4×108 CFU/mL. When the initial bacterial density was 102-103 CFU/mL, psychrophilic bacteria required 2 or 3 days and mesophilic bacteria required more than 4 days to grow above 107 CFU/mL. The above results suggest that understanding the capacity of histamine-producing bacteria to produce histamine and its growth rate in foods is important for the prevention of histamine food poisoning.","PeriodicalId":54373,"journal":{"name":"Food Hygiene and Safety Science","volume":"63 4","pages":"129-135"},"PeriodicalIF":0.2,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40336838","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 repeatable relative standard deviation (RSDr) of intra-laboratories ranged from 0.7 to 1.7%, and the reproducible relative standard deviation (RSDR) of inter-laboratories ranged from 2.0 to 7.3%.
