Is overnight greens "carcinogenic"?

) "Green vegetables overnight can be eaten", "Pesticide residue tea leaves can not make tea containing pesticides", "Fruits can be digged and eaten after one-third of the deterioration is not exceeded", and whether the nutritional value of greenhouse vegetables is half of that of open-air dishes.

26 On the morning of the day, the public welfare lecture on food safety science hosted by the Fujian Science and Technology Association and the Fujian Food and Drug Administration was held in Fuzhou.
The event site provided advice on food safety that the citizens were concerned about, and eliminated all doubts in life
.
At the public welfare lecture that day, Fuzhou University professor and doctoral supervisor Qiu Bin shared the results of his food safety experiment with the audience with the topic of "Rumors and Truths in the Vegetable Basket", and answered various food safety issues that the masses care about in detail.
More than 200 citizens came to listen, and the audience showed great interest in many of his novel statements and participated in the interaction with great enthusiasm
.
Some citizens raised their doubts in life at the scene
.
The experimental results presented by Professor Qiu Bin showed that the overnight greens did not contain nitrites, and there was no risk of “carcinogenesis” at all; the current tea production uses fat-soluble pesticides, and the tea with pesticide residues cannot make tea containing pesticides ( Dimethoate is water-soluble and it is strictly forbidden to use it, otherwise the tea leaves containing dimethoate residues will be poisoned!); the fruit itself will produce ripening agents, and the ripened fruit has no safety and health hazards; formaldehyde is soluble in water and can be cleaned by soaking Removal; shed-grown agricultural products and artificially raised poultry and eggs are as safe as “natural game”.

He pointed out that some online rumors often use the term “long-term consumption may cause cancer” for certain foods.
This argument itself has some implications.
The problem is that there is no scientific basis.
Netizens should not panic when encountering such rumors and do not participate in spreading rumors
.
Qiu Bin also looked forward to an "Internet +" food safety model, and suggested establishing a food safety network platform that aggregates production bases, merchants, cold chain logistics, insurance agencies, and government regulatory agencies to achieve rapid product sales and traceability.
Exclude unsafe food from this safety system and improve food safety
.
He said that the food safety management level of major supermarkets in Rongcheng has been greatly improved, and the public need not worry too much about table safety
.
Table safety has always been highly valued by the party and the government
.
Yang Caiwei, director of the Science Popularization Department of the Fujian Association for Science and Technology, said that in recent years, some food safety incidents that endanger the masses have caused some consumers to panic.
Various food rumors, rumors, and lies have taken the opportunity to disrupt the market and disrupt the market.
The series of lectures are aimed at explaining the rumors in the food field, and enhancing consumers’ scientific consumption ability to recognize fakes and safety.
The "Food Safety Science Popularization Series" will enter communities, schools, institutions, and enterprises, and will be carried out for different groups.
Targeted popular science propaganda
.
The relevant person in charge of the Fujian Food and Drug Administration who attended the lecture that day said that Fujian Province insists on grasping with both hands to do a good job in food and drug safety, and implements the "four strictest" regulatory requirements to ensure "safety on the tip of the tongue.
" At the same time, a lecture on popularization of food and medicine is held, experts are invited to explain the rumors in the food field, and respond to hot and difficult issues that consumers care about.
This move can not only clarify fallacies in time, guide the masses to distinguish between right and wrong, but also effectively popularize food science knowledge.
Enhance the masses’ ability to identify fakes and food safety awareness

Extended reading: Some of the rumors and truth about "Tongue safety".
Rumor 1: "Salt water immersion" and "See who rots fast" can measure the pesticide residues of bayberry.
After the bayberry samples were soaked in salt water for about 10 minutes, the samples crawled out of varying amounts.
A white bug less than 1 cm long
.
According to fruit growers and vendors, the presence of insects means that no pesticides have been sprayed; the bayberry samples were left in a room at room temperature.
After 48 hours, the bayberry samples gradually appeared rot, dry and cracked flesh, and a sour pungent smell from time to time.
According to fruit growers and vendors, this bayberry sample is the least likely to contain pesticide residues
.
The truth: Pesticide residue detection requires professional equipment and a sophisticated process.
The two "earth methods" of "salt water immersion" and "see who rots quickly" are not feasible
.
There are many kinds of pesticides that fruit farmers may spray during the bayberry planting.
Some pesticides cannot completely kill the insects on the bayberry.
Therefore, the insects cannot be used as a basis for testing whether there are pesticide residues
.
In addition, pesticides cannot extend the preservation time of bayberry, and bayberry that has not rotted for a long time cannot indicate that it has been sprayed with pesticides
.
Suggestion: It is best to wash bayberry before eating.
Rinse with water or salt water has a certain effect.
Soak and rinse bayberry with diluted soda water for the best effect.

.
Rumor 2: Using high temperature to eliminate pesticide residues The truth: The authoritative magazine "Food and Chemical Toxicology" reported that Belgian scientists have shown through experiments that frying can remove 90% of pesticides, while boiling water is close to 80%
.
However, high temperature can easily destroy the nutrients of food, and salt water can easily destroy the epidermal cells of fruits and vegetables, which is not worth the loss
