Leather shrimp cadmium exceeds the standard, can you rest assured to eat?

Original title: leather shrimp cadmium exceeded the standard, can you rest assured to eat
Food is the main way to ingest cadmium
Chronic poisoning is the biggest hazard of cadmium
March 24, Jiangsu Provincial Market Supervision Administration issued a notice on the non-conformity of 10 batches of food shows that a store sales of live leather shrimp, cadmium (in cd) does not meet the national standards for food safety, the test results are 1.4mg/kg, the standard value of 0.5mg/ kg. Earlier, the Hunan Provincial Market Supervision Bureau spot inspection found that the chain's local stores sell leather shrimp, cadmium (in cd) detection value of 0.78mg/kg, also exceeded the standard value.
is a soft silver-white metal that is widely found in the earth's crust and contains some cadmium in most soils and rocks. Cadmium is widely used in many industries, such as for the manufacture of bright and long-lasting pigments that color plastics and ceramics, and metal cadmium can also be used to produce batteries.
Cadmium is one of the most commonly contaminated heavy metal elements in food, with the United Nations Environment Programme (DNFP) and the International Commission on Occupational Health Heavy Metals including cadmium as a priority environmental pollutant, while the World Health Organization (WHO) has made it a priority food pollutant and a class 1 carcinogen. The limit of cadmium in seawater shrimp is set at 0.5mg/kg in the National Standard Food For Food Safety (GB 2762-2012). Cadmium harm to the human body is mainly chronic accumulation, long-term large-term intake of cadmium content of food exceeding the standard may lead to kidney and bone damage. For non-smokers, food is the main way to get cadmium. Ingestion of cadmium in the human body will accumulate in the liver and kidneys, causing kidney damage, and lead to the growth of human bones metabolism is blocked, which can lead to various bone lesions.
1960s, a "pain disease" was endemic in Fuji Prefecture, Japan, a cadmium poisoning caused by long-term consumption of cadmium-containing foods. Nerve pain, bone pain and difficulty in movement occur in all parts of the patient's body. By the end of the disease, the patient's bones softened, atrophy, bent limbs, deformed spine, bone brittleness, and even coughing can cause fractures.
the most troubling thing about cadmium poisoning is its long-term nature, and even if it stops eating high-cadmium foods, the harm it causes will continue, such as those in Japan who suffered from it all their lives.
consumption of marine products is limited
normal consumption need not worry about the prevalence of cadmium
in the soil, it will be through soil, water, air flow into the entire ecosystem cycle. With the acceleration of industrial production, cadmium will accelerate the discharge of waste water, exhaust gas and other large quantities into the environment, pollution of water and soil, and then through irrigation, planting and other ways into food. Cadmium will pollute the water source, living in the water fish and shrimp and other animals will inevitably be rich in heavy metal cadmium, leather shrimp is also difficult to escape the claws. Leather shrimp live in water, every day through the exchange of water to breathe, will absorb the heavy metal cadmium in the water, the surface of the skin and water exchange will also seep into some heavy metals. In addition, eating also allows cadmium to enter the skin shrimp body.
, in fact, fish and shrimp shellfish and other aquatic products are inevitable the presence of cadmium, especially in sea crabs, fish and shellfish cadmium in the most cadmium. For example, a survey of coastal areas such as Guangdong and Shandong found that aquatic products are an important source of cadmium intake among local residents.
, can sea products such as leather shrimp still be eaten? In fact, eating leather shrimp heavy metal cadmium risk is still very small, normal eating is not to worry.
, the cadmium content of leather shrimp is not very high. Rice, vegetables, pasta and shellfish are the main foods that consume cadmium, according to cadmium contribution rates from high to low. There is not much cadmium in leather shrimp. What about other foods if you can't even eat leather shrimp?
, the risk of consumers ingesting cadmium is within safe limits. Cadmium, a heavy metal, is harmful to human body, but because it is an environmental pollutant, it is inevitable and can only be minimized. The state has also developed a security line (PTWI) that can be considered to be within the security line without worrying.
According to China's dietary survey data, at present, the average amount of cadmium intake of Our residents is 15.3 mg / kg BW / month, not beyond the safety line, therefore, it can be considered that China's residents cadmium intake exceeds the risk of being too low, do not worry too much. Currently, the WHO's cadmium safety line (PTWI) is based on toxicity to the kidneys, with a maximum weight of 7 micrograms per kilogram per week. This is equivalent to a person of 60 kg, no more than 60 micrograms per day.
again, we don't eat much leather shrimp in terms of frequency and amount of each serving. Some people may say, in case I eat too much, will I be poisoned? In fact, this is also a take for granted. If harm is to be done, the safety line needs to be exceeded over a long period of time and on a daily day. But for the vast majority of people, leather shrimp only occasionally eat, not up to the "daily consumption" and "eat a lot" standard.
of course, concerns about excess cadmium intake are also necessary. After all, cadmium does not do any good to the human body, and cadmium pollution is being paid global attention. For consumers, the best way to reduce cadmium intake is to "keep a distance" from it. Daily life advice starts with the following:
can't eat. Leather shrimp is delicious, but pay attention to control the amount of food, after all, eating any food at once too much, is not a good thing.
try to buy food, including aquatic products, from formal sources. Formal channels, formal manufacturers often have more stringent raw material procurement standards and quality control requirements, but also regularly accept the relevant departments of sampling, such as the occurrence of excessive standards and other issues can be timely to take notification, recall and other means to reduce food safety risks.
eat a variety of foods. Instead of eating just one or more foods, you should refer to dietary guidelines to ensure a variety of foods, each of which not only helps to eat more balanced nutrients, but also reduces cadmium intake.
high cadmium food intake. Appropriately reduce the intake and frequency of some high cadmium foods, such as sea crabs, shellfish, etc.
