I have known that moldy food can't be eaten. But I don’t expect that after eating the polluted food, it will cause such serious harm to the human body.
Picture | Mycotoxins Peanuts (from the Internet)
Recently, the latest food sampling inspection in Jiangxi showed that the fresh peanut sold by RT-Mart (Nanchang Wuhu Commercial Co., Ltd.) exceeded 85 times by standard in aflatoxin B1! The value of detection was 1719μg/kg, while the standard was ≤20μg/kg.
It is necessary to know that aflatoxin B1 is a highly carcinogenic chemical! Its toxic effects are mainly damaging to the liver. So, how does aflatoxin in peanuts come from? In this regard, the China Food Safety Network reporter conducted a survey.
From the Supervision department, peanuts with excessive aflatoxin have been removed from the shelves.
On the afternoon of April 1st, the China Food Safety Net reporter called the Jiangxi Provincial Institute for Drug Testing and Research. The staff said that the inspection is carried out according to relevant national standards. We have provided a copy of the data of inspection, which is a random sampling.
No matter which batches need to be queried, it is certain that the inspection results are accurate.
From the above-mentioned notification, fresh peanut exceeded the standard by 85 times in aflatoxin B1, and how it will be disposed of?
On April 2, interviewed by the China Food Safety Network, the person in charge of the Jiangxi Provincial Market Supervision Administration said that in that afternoon it has been requested to be removed immediately.
Netizen proposed that can peanuts infected with aflatoxin B1 be eaten?
As a high-protein food, peanuts can not only prevent heart disease but also lose weight. Then, if the peanuts exceeding the standard in the toxin B1 sold in supermarkets, can we eat such peanuts? Netizens have expressed their opinions.
@Yazhi: Don't eat. A whole package of peanut needs to be discarded.
@Newspeak: It takes 3-6 months to cause cancer with a daily intake of at least 2.5 mg of aflatoxin B1.
@Fish: Aflatoxin is ubiquitous, and Aspergillus flavus is only harmful to the human body when it produces toxins. Nuts and grains are prone to produce Aspergillus flavus. But Aspergillus flavus is not necessary to produce poison, so it does not necessary cause harm to the human body?
@Universal Beauty: The whole package is not moldy, so I certainly can't discard all and it’s not too wasteful. I think it can be eaten by being washed and put in the pot for twenty minutes, and the germs are gone. The people did not have the money before, they did not pay so much attention to it and they still ate it.
China Food Safety Net reporter found a list of authoritative carcinogens published by the World Health Organization's International Agency for Research on Cancer (IARC) that there are 120 carcinogens on the list. Aflatoxin is classified as a type of carcinogen.
An expert said that mildewed peanut is most likely to have aflatoxin.
Shen Lirong, a professor of food science at the Department of Food Science and Nutrition in Biosystems and Food Science College of Zhejiang University, said in an interview with a reporter from China Food Safety Net that aflatoxin is a highly toxic substance and its toxicity is equivalent to cyanide. Its toxicity is 10 times than that of potassium and about 60 times than that of arsenic. The most common damage of aflatoxin is in the liver tissue.
Strictly speaking, 1 mg may cause cancer, and the intake of 20 mg is fatal to the human at a time. Peanuts are high-protein foods. Therefore, it is more likely to be favored by the people, but we need to pay a lot of attention to storage. Aflatoxin likes to hide on peanuts. If stored improperly, it is prone to mildew.
Why is there aflatoxin on peanuts?
The answer is that the temperature and humidity of raw materials in peanut are not properly controlled during storage, and the quality of raw materials are not tightly controlled before production. And the refining process not reaches the standard or the process is improper, said by Professor Shen Lirong to the China Food Safety Network reporter.
In this regard, Professor Shen Lirong explained that Aflatoxin B1 is one of the aflatoxins, and its toxicity and carcinogenicity are also strongest. It is found in soil, animals and plants, various nuts, especially peanuts, soybeans, grain, and oil products.
At the same time, Professor Shen Lirong also reminded consumers that if the food is moldy and just thrown it away as much as possible.
Dietitian: Once the food is infected with aflatoxin, it is not easy to eliminate the contamination.
The harm of aflatoxin.
Aflatoxin is a relatively common mold. Once it enters the human body, it is extremely harmful to health. In this regard, Yu Yangyang, deputy secretary-general of the Weight Management Committee of the Capital Health and Nutrition Society, and Yu Yangyang, the director of the Capital Health and Nutrition Food Society, accepted the interview of China Food Safety. The reporter said in an interview that aflatoxins mainly contaminate peanuts, corn, rice, soybeans, millet, and other foods and oils. These foods have a high rate of infection. Generally, aflatoxin can cause poisoning, mainly in the following categories.
1. acute poisoning
Aflatoxin mainly damages to liver health in acute poisoning, showing acute hepatitis, hemorrhagic necrosis, etc.
Long-term intake of aflatoxin can cause chronic poisoning in the liver mainly.
3.the largest carcinogenic chemical
Aflatoxin is currently recognized as the most carcinogenic chemical. The aflatoxin symptoms in early include vomiting, stomach discomfort, and abdominal distension.
In this regard, Yu Yangyang also said that the detection rate of aflatoxin in general foods is relatively high. Aflatoxin is heat-resistant and can be lysed at 280 ° C. That is to say, once the food is infected with aflatoxin, the aflatoxin in the moldy food cannot be effectively removed by washing.
When these foods are mildewed, they will produce Trichoderma toxin. It poses a threat to the health of the liver.
A lot of people think that if the food is moldy, the food polluted by mold can be eaten after wiping and clean the mold. However, the vitality of the mold material is tenacious. Even if the mold on the surface is erased, but there are still a lot of harmful substances in the food. Avoiding eating mildew food helps to our health, Yu Yangyang said in an interview with the reporter of China Food Safety Net.
Clinician: People with congenital liver disease should try to avoid eating peanuts.
About related reports, China Food Safety News reporter found that there was a previous investigation by Hong Kong from 1998 to 2000. The inspection results of 115 peanuts and peanut products showed that almost a quarter of peanuts and peanuts were found Aflatoxins in foods and were measured at the level ranging from 1.6 micrograms to 26 micrograms per kilogram. The national limit standards are as follows.
The prevention of aflatoxin.
With the above case, China Food Safety Net reporter consulted Jinan clinical nutritionist. And he said that patients with congenital liver disease can consider avoiding peanuts, peanut butter and other peanut foods as much as possible. The best way to prevent contamination is to keep food in a dry and ventilated place. Even if the food is only mildly musty, and just throw it away immediately.
In this regard, the clinical dietitian also said that in daily life, pay attention to mold and detoxification. Reduce the moisture in the food. To ensure the food stored in a dry and ventilated placed, so that Aspergillus flavus is not easy to grow.
Besides, clinical dietitians also said that chlorophyll can reduce the absorption of aflatoxin and reduce carcinogenic effects. Therefore, It is important to eat more vegetables. Chlorophyll, an excellent chemical protective substance, is very effective against carcinogens from reducing absorption, reducing the effects of carcinogens and genetic material, and the reduction of precancerous lesions in various tissues.
Reminds friends and relatives around you. don't buy moldy food! Don't eat too!
