The cadmium content in rice exceeds the standard.

Review on the study of excessive cadmium in rice

Professor Pan Genxing from the Institute of Agricultural Resources and Environment of Nanjing Agricultural University, in 2007, they conducted random procurement and scientific investigation on more than 70 rice samples of/kloc-0 in six regions of China (East China, Northeast China, Central China, Southwest China, South China and North China), and found that 10 was selected among these more than 70 rice samples. The results of this study are basically consistent with the conclusion that the cadmium over-standard rate is 10.3% as a result of the safety sampling inspection of rice in the national market by the quality supervision, inspection and testing center of rice and its products of the Ministry of Agriculture in 2002.

International standard of cadmium content in rice

At present, the minimum cadmium content of rice in most countries in the world is set below 0.4ppm. The minimum cadmium content of rice in Japan was 65,438+0.0 ppm before 2065,438+00, and a new minimum cadmium content standard of 0.4ppm was implemented in 2065,438+00. The lowest cadmium content of rice in China is 0.2ppm ... The lowest cadmium content of rice in this domestic incident is 0.2ppm- 1.0ppm, which was once a safe range in Japan, but due to the special eating habits of some residents (farmers in polluted areas have a single rice diet and a large daily intake), it still does great harm to human health in China.

Harm of excessive cadmium in rice to human body

According to Liu Immigrant, a poisoning expert and vice president of Guangzhou Twelfth People's Hospital, cadmium is one of the heavy metals harmful to human body. 193 1 The collective "pain" that occurred in Japan in was listed as one of the top ten public hazards in the world: the heavy industrial factory on Mount Fuji discharged industrial wastewater containing cadmium into farmland, causing inexplicable symptoms of systemic pain in nearby residents.

Some experts say that eating cadmium-containing rice poisoning needs long-term accumulation. Generally, people weighing 60 kilograms eat two or two cadmium-containing rice every day, and it will be 50 years before it will cause harm to health.

However, at present, the content of 10% cadmium in domestic rice exceeds the standard, and the situation is different. The hazard of exceeding the standard of 1.0ppm cadmium is different from that of exceeding the standard of 0.4ppm cadmium, and the daily rice intake of some residents in China is more than 2 liang. Therefore, the products with serious cadmium content in rice are still very harmful to human health.

How should ordinary consumers deal with cadmium pollution in rice?

Ordinary consumers don't need to panic about the sudden cadmium pollution in rice. As mentioned above, even if there is rice with serious cadmium exceeding the standard in China, it will take some time for it to do harm to human body, but this incident should arouse consumers' concern about the safe production of rice. Rice safety should continue to pay attention to how the government and industry solve the problem of excessive cadmium in rice at present, so as to lay a good foundation for the food safety of China people in the future.

Since the outbreak of excessive cadmium in rice, a large-scale rice safety survey has been carried out in all parts of China. For ordinary bosses, the demand for rice cannot be fundamentally changed. So how can we prevent cadmium rice from entering our own table at present?

In the face of rice contaminated by heavy metals, the health of China people is almost defenseless. For the huge consumers in China, how to choose pollution-free green rice has become a complicated problem. Experts suggest that brand rice generally has its own base and strict monitoring of land pollution.

At the same time, the people should focus on the enterprises with perfect domestic rice industrial chain to make rice active. It is necessary to focus on the rice industry and complete enterprise equipment from the demand. From the demand side, rice production enterprises are required to make Mi Yuan safe, improve its industrial chain, and urge enterprises to conduct pollution detection on their production bases on a regular basis. For this reason, ordinary consumers should also pay attention to the 20 1 1 China Rice Expo (website: www.mibohui.com), where they can find the brands that consumers trust, and know the trusted rice brands in time through such professional Expo media.

Where should the rice industry in China go?

Poor market supervision is the main reason for the sudden outbreak of cadmium in rice.

Excessive heavy metals in rice come from the pollution of cultivated soil, and the source of land pollution is the result of uncontrolled mining and sewage discharge. However, this interlocking pollution chain is almost undefended in real life. On the one hand, mining enterprises "have almost no environmental protection facilities", and heavy metal pollutants are allowed to drift into soil farmland; On the other hand, it is also undefended to continue to grow rice in the land heavily polluted by heavy metals. "Farmers have not received any planting ban from the government." Finally, rice with excessive heavy metals entered the market and there were no effective preventive measures. "In reality, it can circulate freely."

According to the Food Safety Law, "... food with contents of heavy metals, pollutants and other substances harmful to human health exceeding food safety standards" belongs to "food whose production and operation are prohibited".

This means that heavy metals in rice exceed the standard and trace back to the source. In fact, it is caused by "supervision is not up to standard". It is not only the supervision of environmental protection and soil pollution prevention, but also the supervision of food safety and market order maintenance.

In view of the problem that the cadmium content of rice products 10% in China exceeds the standard, the state food supervision department should take immediate action to conduct safety inspection on the main rice supply in the market, so as to effectively prevent unqualified products from entering the market.

Industry enterprises should pay attention to the interests of consumers and ensure the supply of high-quality rice.

For a long time, most enterprises in the field of food, especially agricultural products, only do downstream, do brands and do consumer goods. However, due to the lack of effective control and management of the upstream, they lack control over the quality of end-consumer products, which eventually leads to all kinds of food pollution.

How to learn from the experience of foreign rice industry, build a rice industrial chain covering the whole process from the field to the table, and focus on comprehensive infrastructure construction from the front end of the industrial chain such as Mi Yuan and processing, so as to provide pollution-free and green food for the market has become a key issue of rice industry. The 20 1 1 China rice Expo (website: www.mibohui.com) to be held in June this year will make every effort to build a platform for the whole industry chain of rice industry and build a rare communication bridge for rice suppliers and buyers. The whole rice industry chain forum will discuss the development trend of the whole rice industry chain with professionals in the upper, middle and lower reaches, and hold a series of rice marketing activities at the rice Expo to deeply select the national pollution-free green rice brands to serve the people.

The Long Road to Food Safety

For China's rice industry, the cadmium pollution in rice exceeds the standard, which is mainly caused by the weak supervision of the regulatory authorities and the weak concept of safe production in some enterprises in the industry. Food safety in China has become a highly polluting industry.

Regular soil sampling survey and rice safety self-inspection in rice production base are the safety production systems that brand rice enterprises should take the lead in establishing. At the same time, the industry should establish a clear safety production system, and conduct regular safety inspections on enterprises in the industry to ensure the continuous supply of high-quality rice in China market.

In response to this incident, all rice suppliers should actively accept relevant national food safety inspections to create a good environment for the healthy development of the domestic rice industry. At the same time, enterprises should also actively create safe and green food and assume their due responsibilities and obligations. To the cadmium pollution incident in rice, no company has clearly declared that its brand has not been polluted, and the long road of food safety still needs our careful care.
