Japan and food

Machiko Usui, Masayuki Akashi
Oral mite anaphylaxis (OMA) caused by mite-containing food that was initially reported in 1993 has become commonly known after accumulating the case reports. Although it has been pointed out as being related to aspirin intolerance overseas, there are only a few cases reported in Japan so far, particularly no case for children. We report a child case which is seemingly related to OMA and aspirin intolerance. The case is for a boy at the age of 10. After eating Takoyaki with the ingredient of mite-containing flour, he was diagnosed as OMA due to the occurrence of anaphylaxis with respiratory discomfort, abdominal pain, and vomiting...

High salt intake is one of the major dietary determinants of hypertension and cardiovascular disease in Japan and throughout the world. Although dietary salt restriction may be of clinical benefit in salt-sensitive individuals, many individuals may not wish, or be able to, reduce their intake of salt. Thus, identification of functional foods that can help protect against mechanistic abnormalities mediating salt-induced hypertension is an issue of considerable medical and scientific interest. According to the "vasodysfunction" theory of salt-induced hypertension, the hemodynamic abnormality initiating salt-induced increases in blood pressure usually involves subnormal vasodilation and abnormally increased vascular resistance in response to increased salt intake...

BACKGROUND: The infection in dogs due to canine parvovirus (CPV), is a highly contagious one with high mortality rate. The present study was undertaken for a detailed genetic analysis of partial VP2 gene i.e., 630 bp isolated from rectal swab samples of infected domestic and stray dogs from all areas of district Faisalabad. Monitoring of viruses is important, as continuous prevalence of viral infection might be associated with emergence of new virulent strains. METHODS: In the present study, 40 rectal swab samples were collected from diarrheic dogs from different areas of district Faisalabad, Pakistan, in 2014-15 and screened for the presence of CPV by immunochromatography...

The current review examined published data on the intake of all major low-/no-calorie sweeteners-aspartame, acesulfame-K, saccharin, sucralose, cyclamate, thaumatin and steviol glycosides-globally over the last decade. The most detailed and complex exposure assessments were conducted in Europe, following a standardized approach. Japan and Korea similarly had up-to-date and regular intake data available. The data for other Asian countries, Latin America, Australia/New Zealand and global estimates, evaluated by the Joint FAO/WHO Expert Committee on Food Additives (JECFA), while available, were shown to be more limited in terms of design...

Bellflower root ( Platycodon grandiflorum ), which belongs to the Campanulaceae family, is a perennial grass that grows naturally in Korea, northeastern China, and Japan. Bellflower is widely consumed as both food and medicine due to its high nutritional value and potential therapeutic effects. Since foodborne disease outbreaks often come from vegetables, understanding the public health risk of microorganisms on fresh vegetables is pivotal to predict and prevent foodborne disease outbreaks.We investigated the microbial communities on the bellflower root (n=10)...

Polycyclic aromatic hydrocarbons (PAHs) are carcinogenic substances that are mainly generated during heating in food; therefore, the European Union (EU) has regulated the amount of benzo[a]pyrene and PAH4 in various types of food. In addition, the Scientific Committee on Food of the EU and the Joint Food and Agriculture Organization/World Health Organization Expert Committee on Food Additives have recommended that 16 PAHs should be monitored. Since coffee beverages and dark beer are roasted during manufacture, monitoring these 16 PAHs is of great importance...

In September 2016, 140 patients with primary symptoms of sore throat and fever were identified in a school dormitory in Osaka, Japan. Epidemiological and laboratory investigations determined that this symptomatic condition was a food-borne outbreak of group G Streptococcus (GGS), with GGS being isolated from samples from patients, cooks and foods. The strain of GGS was identified as Streptococcus dysgalactiae subsp. equisimilis (SDSE) of two emm types ( stG 652.0 and st C36.0). The causative food, a broccoli salad, was contaminated with the two types of SDSE, totaling 1...

Salmonella enterica serovar Typhimurium ( Salmonella Typhimurium) and its monophasic variant ( Salmonella 4,[5],12:i:-) are the major cause of gastroenteritis in both humans and animals. Pulsed-field gel electrophoresis and multilocus variable-number tandem-repeat analysis have been used widely as subtyping methods for these pathogens in molecular epidemiological analyses, but the results do not precisely reflect phylogenetic information. In this study, we performed a phylogenetic analysis of these serovars using whole-genome sequencing data and identified nine distinct genotypic clades...

Due to the course of registration of pesticides in Japan, the Food Safety Commission (FSC) has the responsibility to make a risk assessment of residual pesticides and related chemicals through foods. Among the set of safety evaluations for pesticides, genotoxicity assay data are mandatory. The standard test battery for this evaluation consists of a bacterial gene mutation assay, in vitro mammalian chromosomal aberrations and/or other chromosome damage assay, and in vivo rodent micronucleus assay. These assay outcomes are used for mechanistic consideration of carcinogenicity, if any...

Background: Understanding feedback between above- and below-ground processes of biological communities is a key to the effective management of natural and agricultural ecosystems. However, as above- and below-ground food webs are often studied separately, our knowledge of material flow and community dynamics in terrestrial ecosystems remains limited. Results: We developed a high-throughput sequencing method for examining how spiders link above- and below-ground food webs as generalist predators...

The traditional consumption of edible insects is common in one third of the world's population, mostly in Latin America, Africa and Asia. There are over one thousand identified species of insects eaten in some stage of their life cycle; and they play important roles in ensuring food security. The most common way to collect insects are from the wild, which is seasonal with limited availability and has an increasing demand resulting in a disruption to the ecosystem. There is a growing interest shown in rearing insects for commercial purposes, and an industrial scale production will be required to ensure steady supplies...

Soybeans (Glycine max (L,) Merr,) contain γ-glutamyl peptides and oligosaccharides, and these components play an important role in imparting the "kokumi" taste to foods. To gain insight into the genetic diversities and molecular mechanisms of accumulation of γ-glutamyl peptides and oligosaccharides in soybean, we measured the contents of these components using the Japan and World mini core collections. Similar to other previously reported traits, wide variations were detected among the accessions in the core collections with respect to the content of γ-glutamyl peptides and oligosaccharides...
