Severe tetrodotoxin (TTX) poisoning due to small gastropods has been documented in Japan. In this study, we investigated the TTX content of the muscles and viscera of Nassarius sufflatus collected off the coast of Futaoi Island, Shimonoseki, Yamaguchi Prefecture, Japan, to prevent the occurrence of TTX poisoning caused by this small gastropod. Live specimens were obtained, and their muscles and viscera were collected. Test solutions were prepared from tissues of specimens and analyzed for TTX by HPLC-fluorescence detection. TTX was detected in both tissues at concentrations ranging from <0.1 to 18.2 μg/g for muscle and <0.1 to 130.7 μg/g for viscera. These results suggested that N. sufflatus accumulates TTX not only in its viscera but also in its muscles, and that precautions should be taken to prevent food poisoning due to this gastropod.

A method for the rapid analysis of multiclass residual veterinary drugs in poultry muscle, egg, and raw milk was validated in accordance with Japanese guidelines. Using LC-MS/MS, 20 veterinary drugs, including sulfonamides, coccidiostats, and macrolides were analyzed in one injection. 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. These results suggest that continuous monitoring for a new trend of veterinary drugs is necessary.

We modified a method for determining methanol content in detergents used in kitchens. Furthermore, an inter-laboratory study was conducted in 10 laboratories to validate the modified method. In this study, two concentrations of samples were blindly coded. Each laboratory determined the methanol content in each sample according to a protocol. The determined values were statistically analyzed according to an international harmonized guideline. HorRat values were calculated based on the reproducibility relative standard deviation (RSDR) which was estimated from the interlaboratory study, and predicted RSDR calculated from the Horwitz/Thompson equation. The HorRat values of the two samples were 0.8 and 1.8, meeting the performance criteria of less than 2 set by the Codex Alimentarius for analytical method approval. These results confirm that this modified analytical method shows good performance as an analytical method for determining methanol content in kitchen detergents.

By using the LC-MS/MS method developed by us, we determined the residual amounts of acaricides in honey samples commercially available in Tokyo from April 2015 to March 2021. The results of analyzing 127 honey samples, amitraz was detected in 85 samples at the level of 1.1-34.1 μg/kg. Propargite was detected in 3 samples at 2.4-3.8 μg/kg. None of them was beyond the Japanese MRLs or uniform limits. In these survey for 6 years, amitraz was detected in high rate throughout the year. But, the present results imply that amitraz has been used properly in actual bee-keeping because of no violation of MRL and less fluctuation in the detected levels. On the other hand, propargite was detected at the levels over LOQ in domestic honey samples for the first time in 2020, which may suggest a new trend of acaricide use in apiculture in Japan.

After washing the cooking utensils used to prepare liquid batter, flour may remain in the scrubbing sponge. 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.

An isolation method for Acromelic acids A, B and Clitidine, which are venomous constituents of Paralepistopsis acromelalga was developed. Highly purified products were obtained from the mushroom extract using silica gel, ODS, ion-exchange column chromatography and preparative TLC. Using those results, we optimized the LC-MS/MS conditions. Finally we developed a method for simultaneous analysis. In recovery tests, the average recovery was 80.8-112.4%, repeatability was 1.4-3.8RSD%. The limits of quantification of the respective compounds were estimated as 0.25 μg/g. Based on the results, this method can reveal causes of food poisoning by Paralepistopsis acromelalga.

The total mercury content in 112 fishery products, purchased from Osaka city during 2013-2018, was measured using a heating vaporization mercury analyzer. The average total mercury content in all tuna processed products was found out to be 0.115 μg/g (median=0.070 μg/g). Notably, albacore tuna exhibited the highest mercury content with an average concentration of 0.301 μg/g (median=0.296 μg/g). The total mercury concentration of the fishery products, except processed tuna and Kezuribushi (comprising shavings of dried and smoked mackerel, sardine, as well as horse mackerel), was generally low (<0.1 μg/g).The provisional tolerable weekly intake (PTWI) for mercury as set by the Joint FAO/WHO Expert Committee on Food Additives is 4.0 μg/kg body weight/week. On an average, for Japanese diet, the total weekly mercury intake from fishery products for a person weighing 50 kg was estimated to be 0.13 μg/kg body weight/week, which was 3.3% of the PTWI. These values indicate that it was not a problem to consume fishery products normally. However, albacore tuna cans have a relatively high total mercury concentration; thus, pregnant women consuming them daily may exceed the tolerable weekly intake of methylmercury (2 μg/kg body weight/week) as set by the Food Safety Commission of Japan.

A rapid, easy and versatile, simultaneous analytical method based on three-layer extraction was developed for the determination of 6 fungicides in lemon. In this method, degreasing with n-hexane, partitioning into acetonitrile, and purification by the salting-out effect were simultaneously performed after extraction with acetone. It allowed to prepare a test solution without concentrating, transferring, and purification using solid phase extraction column.As a result, 6 fungicides in lemon met the management criteria of the guideline for validity assessment (Ministry of Health, Labour and Welfare in Japan). Thus, the present method could be useful for a rapid determination of fungicides in lemon.

From 2012 to 2017, many adverse events, such as irregular vaginal bleeding and menstrual disorders, associated with the use of health foods containing Pueraria mirifica were reported in PIO-NET. Health foods containing P. mirifica claim mastogenic or body shaping effects, and it is for this reason that many women use these products. As a result, the Japanese government investigated and assessed the possibility of the occurrence of adverse effects associated with the use of other ingredients in health foods and labelled P. mirifica, Coleus forskohlii, black cohosh, and greater celandine as "designated ingredient, etc."The present study showed that recognition of "designated ingredient, etc." was 45.9% and that there was a difference between consumers and healthcare professionals. The prevalence of food containing P. mirifica use was 1.2%. Almost half of users experienced adverse events, such as irregular vaginal bleeding and menstrual disorder. Some subjects had a good perception towards "designated ingredient, etc.," such as "It seems effective"(32.7%) and "It seems good for health"(18.9%). After reading the descriptive text, their positive perceptions decreased.In conclusion, the recognition of "designated ingredient, etc." is insufficient. To avoid adverse events associated with "food containing designated ingredient, etc.," detailed information should be provided.
