Introduction Arsenic (As), a naturally occurring metalloid, is widely distributed in air, soil and groundwater in both organic and inorganic forms. Current knowledge indicates that organic forms of As have relatively low toxicity, but inorganic As (iAs) is a non-threshold human carcinogen [1]. FOOD SAFETY NEWS 05/05/20 Researchers find arsenic in rice risk for UK infants. Scientists have found half of rice varieties they tested exceeded maximum arsenic limits for young children in the United Kingdom.

FOOD SAFETY NEWS 05/05/20 Researchers find arsenic in rice risk for UK infants

A team at the University of Sheffield’s Institute for Sustainable Food found 28 of 55 rice samples sold in the U.K. contained levels of arsenic that exceeded European Commission regulations for rice for infants or children under the age of five. The U.K. follows European Commission regulations so that inorganic arsenic concentrations must be below 0.20 milligram per kilogram in white (polished) rice and less than 0.25 mg per kg in brown (unpolished) rice. However, the concentration in rice used for infant food production or direct consumption is set at a maximum of 0.1 mg per kg.

This study is aimed at investigating a suitable method for rice sample preparation as well as validating and applying the method for monitoring the concentration of total arsenic, cadmium, and lead in rice by using Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Various rice sample preparation procedures were evaluated.

The analytical method was validated by measuring several parameters including limit of detection (LOD), limit of quantification (LOQ), linearity, relative bias, and repeatability. Regarding the sample preparation, recoveries of spiked samples were within the acceptable range from 89.3 to 98.2% for muffle furnace, 94.2 to 103.3% for heating block, 81.0 to 115.0% for hot plate, and 92.8 to 108.2% for microwave. Validation parameters showed that the method fits for its purpose, being the total arsenic, cadmium, and lead within the Brazilian Legislation limits. 1. 2. 2.1. 2.2. 2.3. 2.3.1. 2.3.2. 2.3.3. 2.3.4.

ENVIRONMENTAL TOXICOOGY 10/08/17 Environmental behavior, potential phytotoxicity, and accumulation of copper oxide nanoparticles and arsenic in rice plants. Rice has served as an important human food source for more than 8000 yr and has played an essential role in the process of Asian civilization and urbanization 1. Historically, rice has been and continues to be the main food source for half of the world's population, because of its easy transportation and storage and relatively short cooking time 2, 3. Globally, 42% of the 2868 kcal energy consumed daily by the average person comes from cereal crops in which rice is the dominant grain 4. GAO_GOV 16/04/18 Federal Efforts to Manage the Risk of Arsenic in Rice. PLANT BIOTECHNOLOGY JOURNAL 04/12/17 Genetic-based dissection of arsenic accumulation in maize using a genome-wide association analysis method.

Summary Understanding the mechanism of arsenic (As) accumulation in plants is important in reducing As's toxicity to plants and its potential risks to human health. Here, we performed a genome-wide association study to dissect the genetic basis of the As contents of different maize tissues in Xixian, which was irrigated with As-rich surface water, and Changge using an association population consisting of 230 representative maize inbred lines. Phenotypic data revealed a wide normal distribution and high repeatability for the As contents in maize tissues. The As concentrations in maize tissues followed the same trend in the two locations: kernels < axes < stems < bracts < leaves.

In total, 15, 16 and 15 non-redundant quantitative trait loci (QTLs) associated with As concentrations were identified (P ≤ 2.04 × 10−6) in five tissues from Xixian, Changge, and the combination of the locations, respectively, explaining 9.70%–24.65% of the phenotypic variation for each QTL, on average.

QUEEN'S UNIVERSITY 22/07/15 Queen’s researchers discover simple solution to worrying levels of arsenic in our rice.

Queen’s researchers discover simple solution to worrying levels of arsenic in our rice Researchers at Queen’s University Belfast have made a breakthrough in discovering how to lower worrying levels of arsenic in rice that is eaten all over the world. After many laboratory experiments, they have discovered that a simple, shop-bought coffee percolator is the best method for removing the carcinogen, inorganic arsenic, from all types of rice, including white and wholegrain. The results are published in the PLOS ONE journal today. Rice is the only major crop grown under flooded conditions.

It is this flooding that releases inorganic arsenic, normally locked up in soil minerals, which is then absorbed by the plant. BFR 11/06/15 Rice and rice products contain high levels of inorganic arsenic The BfR recommends investigating possibilities of minimising the levels of arsenic in rice products. De l’arsenic dans le riz: pas de panique. Suite aux messages alarmants en provenance des USA, des doutes ont également été soulevés dans notre pays au sujet de la présence d’arsenic (un métal potentiellement toxique) dans le riz et les produits à base de riz.

Ainsi, les boissons à base de lait de riz devraient-elles à tout prix être évitées chez les nourrissons, car elles seraient mortelles! D’après notre test, cette panique est toutefois infondée. Qui mange de façon variée et équilibrée ne court aucun risque et les produits à base de riz demeurent une bonne option pour les enfants allergiques au lait de vache. Toutefois, nous exigeons qu’une norme légale soit enfin approuvée au niveau européen.

En effet, il ressort de notre test que certains produits flirtent quand même avec les limites de l’acceptable. ScientificWorldJournal. 2014; 2014: 596438.

PARLEMENT EUROPEEN - Réponse à question E-005479-13 Surdose de riz mauvais pour la santé (Arsenic) Les autorités de sécurité alimentaire au Danemark ont déconseillé mercredi aux parents les gâteaux au riz et le lait de riz pour les enfants, en raison de la concentration en arsenic. Le riz contient naturellement de l'arsenic inorganique, et «les personnes consommant quotidiennement des aliments avec de l'arsenic inorganique courent un risque accru de cancer», ont-elles expliqué sur leur site internet.

Elles ont appelé les parents à être «particulièrement attentifs» à la consommation des enfants, en raison de leur poids, et à éviter les boissons au riz et le lait de riz, ainsi que de donner des céréales au riz soufflé chaque jour.

Between March and May 2013, three multi-country outbreaks of hepatitis A virus (HAV) infection were reported through the Epidemic Intelligence Information System for Food- and Water-borne diseases (EPIS-FWD) of the European Centre for Disease Prevention and Control (ECDC).

The aim of this work is to put these outbreaks into a European Union (EU) and European Economic Area (EEA) perspective and highlight opportunities for improving detection and investigation of such outbreaks. Although HAV outbreaks are not unusual in the EU/EEA, having three large food-borne multi-country outbreaks declared within three months is an unexpected event, particularly when at least two of these outbreaks are associated with frozen berries.

Surveillance and early warning for hepatitis A virus infection in the European Union and countries of the European Economic Area Hepatitis A is a self-limiting viral disease caused by hepatitis A virus (HAV).
