"We are really surprised, we expected and thought that the restrictions would lead to a fall in the level," says Petra Bergkvist, state inspector in Sweden's Food and Treatment Authority TT.
New limit values for The poison was introduced on January 1, 2016, after an emergency report on the high concentrations of inorganic arsenic in rice. The authority tested eight different rice before and after the limit values were introduced and found that the poisoning content increased in six of them.
The product, a lot of rice with cereals, was withdrawn from the market because the value was too high. The remainder is still below the border.
Why arsenic levels increase despite the fact that the regulation is currently unclear.
"Within the boundaries, it may be that the companies are a little more careful, more carefull to have their customers lower levels. With the limit that has become possible, other rice varieties can be placed on the market than before, because you still did not know where the boundary would be , says Petra Bergkvist.
Several products had value which lay around the limit value, but the Swedish Food Safety Authority took into account the statistical uncertainty, which means that it can not be sure that the levels are so high that the products should be withdrawn.
Arsenic growth is highest in two organic rice. Products with the highest levels are also organic.
"We made a statistical comparison and this is not just a difference in eyes, but a statistically comparable, significant difference," says Bergkvist.
Arsenic is naturally in the substrate and takes rice over soil or irrigation water. Levels are usually not affected by additives or handling procedures. Why organic rice has higher levels of toxicity, the Swedish Food Safety Authority has no answer at this time.
New measurements are causing there are no changes in the recommendations of the Food Safety Authority. At least not at the moment. As adults, you should not eat more than six servings of rice per week, and as a child should not eat more than four. Parents should also not give children under six years of risk or rice.
Rice with whole grains should sometimes be selected. And do not mix with water when cooking.
– It is good to cook rice in excess of water, which is then poured. The inorganic arsenic dissolves in water and can be solved only by changing these habits, "says Petra Bergkvist.
The National Food Board also looked at the pulp and vellum for children and found that the levels of cadmium and lead had decreased from previous research in 2011. For children's food, stricter legislation is applied and the industry seems to be adapted, according to Petra Bergkvist.
"Children's food businesses have a good idea of the cadmium and lead constituents because they know that parents really want to watch it," she says.
Arsenic is an element found in the foundations and the soil. Arsenic has no smell, taste or color when mixed in water, even when the doses are high. If you get a high level of time, you are at greater risk of skin, lung, bladder and possibly kidney and liver cancer.
Arsenic can also lead to cardiovascular diseases and diabetes. Foster and children are particularly sensitive to the topic.
Apparently rice is sensitive to the absorption and storage of high levels of arsenic. If it is ecologically pyrrhised or not, it does not matter when the substance is naturally present in the soil.
