Is "car freedom" dangerous? The food safety hazards we ignored in those years

Produce report recently, Nanning's Ms. Wang received 2 boxes of cars sent by relatives and friends, for 5 consecutive days ate more than 6 pounds, did not expect a few days later, abdominal sudden cramp, the appearance of "blood poop", ran back and forth to the bathroom more than 20 times, and finally fainted in the bathroom.
: Daily Economic News Officer Dr. Bo diagnosed Ms. Wang with iron poisoning or cyanide poisoning due to eating too many hot fruits.
is a rare but potentially deadly poison that prevents human cells from consuming oxygen properly.
: The daily economic news officer Bo toxic cyanide includes hydrogen cyanide gas, crystal solids, potassium cyanide and sodium cyanide.
1811, Joseph Louis Gay-Lussac prepared pure hydrogen cyanide.
Cyanide Structure Map@shutterstock Common cyanide poisoning when it comes to cyanide, most people have a spy movie scene in mind: a man swallows a pill and spits it out.
but also encountered on a daily basis.
detection of cyanide poisoning can be difficult.
common cyanide poisoning is found in the following cases: smoke photography in fires, chemical research, synthetic plastics, metalworking and electroplating and other industries plants (e.g. apricots and cassava) to treat cancer drug cigarette smoke cyanide poisoning detection is very difficult due to cyanide Ions (CN-) have a strong affinity with the tricolor iron (Fe3 plus) of cytochrome oxidase, and hydrogen cyanide is easily absorbed in combination with iron in hemoglobin and circulates rapidly to the liver, kidneys, brain and blood tissue, leading to health problems.
cyanide inhibits cytochrome oxidase, so oxygenated hemoglobin does not release oxygen in tissues, leading to increased blood sugar and lactic acid, as well as a decrease in ATP/ADP ratios, marking a shift from aerobic metabolism to anaerobic metabolism.
principle of cyanide poisoning in mitochondrials Fred M. Henretig et al. Hazardous Chemical Emergenciesand Poisonings. The New England Journal of Medicine (2019). DOI: 10.1056/NEJMra1504690 Cyanide poisoning symptoms are similar to those experienced while climbing at high altitudes, including: general weakness, strange behavior, drowsiness, coma, shortness of breath, headache, dizziness, vomiting, abdominal pain, cramps, etc.
people's skin can sometimes turn pink or cherry red, and both breathing and heartbeat can become very fast.
we divide cyanide poisoning into two types: acute and chronic.
cyanide poisoning has adverse effects on the central nervous system, cardiovascular, endocrine and respiratory systems.
symptoms include breathing, decreased blood pressure, dizziness, headache, stomach pain, vomiting, diarrhea, insanity, coma, convulsions and death.
Chronic cyanide poisoning long-term exposure to low concentrations of cyanide may lead to chronic cyanide poisoning, poisoning is manifested as a gradual onset, may occur headache, taste changes, vomiting, chest pain, abdominal pain, anxiety, and may lead to malnutrition, congenital malformations, neurological diseases and spinal cord diseases and other problems.
5 foods containing the toxin cyanide in addition to the car lith mentioned above, in fact, there are more than 2000 kinds of natural plants in the world containing the toxin cyanide, here we highlight the most common types.
such as cassava, sorghum, cocoa powder, apples, almonds.
mention cassava, first we think of cassava powder, which is known as the "King of Starch."
more than half a billion people around the world use cassava as a staple food.
, cassava is an important source of energy in the tropics, second only to rice and maize, according to the Food and Agriculture Organization.
the cassava leaves we know are rich in protein, vitamin C, vitamin A and dietary fiber.
, however, all cassava varieties contain cyanide, including China's local bread cassava, South China 9, South China 6068, South China 12 and GR891 and other varieties.
Those who use cassava as a staple food and normally have low iodine intake (-lt;100 μg/day) may experience endearing goiter (or develop neck lumps, wheezing, breathing difficulties, coughing, etc.) and kertin disease (a form of sclerosis).
According to the December 2020 Straits Journal of Preventive Medicine records: cassava toxic substances (cyanide) content, often due to planting season, varieties, soil and fertilizer and planting time and other factors, but the upper cortical cyanide content is the highest, up to 50% to 65%, cassava cyanide hydrolyzed, released hydrogen cyanic acid and absorbed into the blood by the human mucosa caused poisoning.
Cassava poisoning has the characteristics of rapid onset and high fatality rate, and food shortage leads to the consumption of a large number of fresh, uncooked and imperfed cassava in a state of hunger, which is the main internal cause of poisoning.
2019, a villager in Hengxian County, Nanning City, collected cassava to cook for his family to eat, due to improper processing, resulting in the illness of three people, one of whom died of poisoning.
after The investigation of cassava poisoning incident in Nanning City found that: the consumption is very large, the younger symptoms are heavy, the incubation period is 4 to 12h.
17 clinical manifestations of 4 cassava poisoning incidents were performed to the east, Zhang Jing, Long Xi, Wei Yang and Ma Lingling. Analysis of 4 cassava poisoning incidents in Nanning City. Nanning Center for Disease Control and Prevention. For people in Africa, they also ate large amounts of cassava roots, while the affected individuals showed upper limb symmetrical reflexes, lower limb symmetrical spastic paralysis, spastic speech impairment, vision loss, peripheral neuropathy, cer cerebral syndrome and hearing loss.
is one of the most important crops in Africa, Asia and Latin America.
more than 35 per cent of sorghum is used for human consumption, while others are used for animal feed, alcohol raw materials and industry.
sorghum contains cyanne, bitter glycoside and bitter almond glycoside, which is called cytoside, and its content at the tip of the seedling stem is about 30% of the dry weight.
with the increase of sorghum plant age, the content of sorghum glycosides decreased gradually, and the content of immature sorghum leaves was higher than that of mature sorghum leaves.
fruits and nuts contain the potentially toxic compound bitter amygdala.
, is a common fruit, rich in vitamins, is good for people's health.
"One apple a day, disease away from me", from this saying, we can see people's love and trust in it.
its flesh is really nutritious, but it's mixed with the deadly toxin, the apple seed.
USA Today apple seeds contain toxic cyanide, but the amount is relatively small, an apple seed will not poison people, at most after eating uncomfortable.
but eating in large quantities is completely toxic, so be sure to remove the seeds when eating apples.
its seeds contain a certain amount of bitter amygdala (consisting of cyanide and sugar) that, when metabolized in the digestive system, breaks down into highly toxic hydrogen cyanide.
studies have shown that the bitter almond glycoside content in apple seeds is between 1 and 4 mg/g, while the bitter almond glycoside content in apple juice is between 0.001 and 0.08 mg/ml.
similar to apple seeds is cherries, which also contain a lot of cyanide, more than apple seeds, with a slight breakage that immediately produces hydrogen cyanic acid.
so don't suck and chew the seeds when you're eating cherries.
addition, cherries and plums, apricots, and peaches come from the same family, and the seeds of these fruits contain highly toxic compounds that cannot be eaten directly.
is a fruit rich in protein, minerals, vitamins and amino acids.
almonds, there are bitter and sweet two.
bitter almonds, which contain a lot of bitter almond glycosides, and therefore should not be consumed.
of sweet almonds is low and relatively safe to eat.
eating unprocessed or improperly processed almonds can cause severe acute illness and may even lead to death.
In the human liver, about 80% of cyanide needs to be detoxified by thiocyanate enzymes in mitochondrials, and there are two detoxification mechanisms: high iron hemoglobin in red blood cells, which temporarily mediates cyanide through reversible reactions.
another, the conversion of cyanide into less toxic thiocyanate (SCN) is slowly excreted through urine and sweat, a process catalyzed by thiocyanate enzymes.
, of course, there are other detox mechanisms.
the United States, there are several detoxification therapies for cyanide, including the use of nitrites and sulfates, hydroxycobalamines, etc.
attention! Foods containing natural toxins also contain natural toxins, according to Fox News, and some fruits and vegetables also contain natural toxins, which are safe to eat occasionally but must never be consumed on a regular basis.
2012, IARC noted that rice may be an important source of inorganic arsenic (iAs made up of As III and As V).
brown rice contains more iAs than white rice.
addition to iAs, rice contains lower concentrations of less toxic organic arsenic (oAs) compounds, such as dmethyl arsenic acid (DMA) and trace amounts of methyl arsenic acid (MMA).
exposure to arsenic can affect every organ of the body and can lead to skin damage, cancer, diabetes and lung disease.
the toxin can cause adverse reactions such as vomiting, abdominal pain and dizziness if consumed in large quantities.
, however, is less likely to eat too much rice a day, so poisoning is less likely and long-term exposure to low doses of arsenic can lead to heart disease and bladder cancer.
October 29, 2020, in Science of Total Environment, researchers found that the newly developed PBA (boiling absorption method) was most effective in reducing iAs, with brown rice and white rice iAs 54% and 73% lower than raw rice, respectively.
four cooking methods were selected, and three repeated trials were conducted on all six rice types, Manoj Menon et al, Improved rice cooking approach to maximise arsenic removal while preserving nutrient elements, Science of The Total Environment.DOI: Potatoes produce aubergine, a compound concentrated in when potatoes sprout and eat green potatoes.
symptoms of aubergine poisoning include vomiting, diarrhea, and sometimes cardiac arrest.
a study by the University of New Mexico in New Mexico, an adult of about 45 kilograms must eat 0.4 kilograms of completely green potatoes to be poisoned.
Spring Festival is coming to celebrate, family reunion, visit friends and relatives, in the family gathering time to pay attention to food safety.
as individuals, we need to take some measures to prevent food poisoning.
addition to the above mentioned food needs to pay attention to, seafood, game, long-term food should also pay attention to.
fish head, fish gills, animal liver and other areas are susceptible to heavy metal pollution, and secondly, fruit beavers, rollers, hedgehogs, wild snakes and other wild game is also inedible.
your daily diet safe Tips Clean: Wash your hands before handling food.
use clean tap water, and apply hand sanitizer, hands wash 20s, use clean paper towels to dry hands.
after handling fresh food or before processing cooked food, can not touch the mouth, nose, eyes and other parts.
to keep the kitchen hygienic and clean, such as cutlery, chopstick cages, knives and chopping boards, especially rags.
Separate: To avoid cross-contamination, if you only have one cut plate, consider buying another one for meat and seafood, one for fruits and vegetables, which, after use, needs to be put in the dishwasher and rinsed and disinfected with scrubs and hot water.
cooking: The general principle of cooked thoroughly is to cook the pan for another 10-15 minutes for longer meat.
when encountering snails, shells, crabs and other aquatic products, raw, half-baked, wine bubble, vinegar bubble or salted after direct consumption method is not safe.
For the method of killing the new coronavirus, heat for more than 15 minutes when the water temperature is at 56 degrees C, for more than 3 minutes when the water temperature is at 70 degrees C, and when the water temperature is at 100 degrees C for one minute.
: The refrigerator is not a safe, some cold bacteria such as listeria, colitis Yersinia can grow, so the food taken out of the refrigerator should be thoroughly heated or cleaned before eating.
ventilation: the kitchen should always open the window ventilation, keep clean, moderate disinfection.
