Fu Bao look at the title
Guess what it is?
That's right!
It is
Let's be on the side of the road and at some fruit stands
Common fresh fruit cuts
One serving of fresh fruit cut
It is often possible to get several different fruits
You don't have to wash it yourself, you don't have to cut it yourself
It's simply not too convenient to eat
But
This seems to be a wonderful cut of fresh fruit
in all probability
will become a "sparse artifact"
In fact
Buy a box of clean and hygienic fruit cuts
From the quality of the fruit to the production process
and then to storage conditions
Every step of the way should not be underestimated
Among them, there are the following security risks
Moldy fruits are indiscriminately filled
It is not excluded that there will be "active" merchants who will cut off the rotten part of the fruit and leave the good-looking part to cut the fruit.
Rotten fruit is common in two situations:
One is because of local tissue damage caused by frostbite or bumps, which can be cut off and continue to eat, but it should be eaten as soon as possible, as it is easy to breed bacteria after a long time;
The other is that the fruit is rotten due to poor storage, although the fruit looks like only a small part of the fruit is broken, but in fact, the whole fruit may have been contaminated, even after the spoiled part is removed, it is not recommended to continue to eat.
Some organizations have collected some rotten fruit samples in the market for microbial and mycotoxin detection and analysis, including peaches, apples, and grapes that we commonly eat. It was found that after the fruit was partially rotten or moldy, the microbial contamination of the whole fruit was very high, such as E. coli, Staphylococcus aureus, mold, etc. Many fruits that have rotted a little, even the number of colonies in the intact parts are exceeded, and the degree of contamination is not low, but we can't see it with the naked eye.
Therefore, fruit deterioration is not only a superficial phenomenon, but also quietly penetrates into various parts. The best way to dispose of it is to discard it whole, and it is really difficult to distinguish the processed street fruit cuts.
The health situation is worrying
01
Don't wash your hands carefully
Our hands look clean, but they're actually dirty. In a study of 51 healthy college student volunteers, a total of 25 groups of bacteria were detected on the palms of 27 male and 24 female volunteers, of which three groups (Actinomycetes, Firmicutes, and Proteobacteria) accounted for 94% of them.
If you don't clean your hands thoroughly before cutting the fruit or don't wear disposable gloves, bacteria on your hands can contaminate the fruit. Some people will also look at their mobile phones while cutting fruits, and there are pathogenic bacteria such as Staphylococcus epidermididis, Escherichia coli, enterococci, Candida, Staphylococcus aureus, and Salmonella on the surface of mobile phones, which can easily contaminate food.
02
Fruits are not peeled
Some fruits are not peeled, but they must be washed before peeling. For example, cantaloupe may carry listeria, which can cause vomiting, diarrhea, fever, muscle aches, and in severe cases, coma, shock, and death.
03
Knives and cutting boards are unhygienic
Knives and cutting boards that come into contact with the peel are not carefully cleaned to breed bacteria, and there is a high risk of cross-contamination when used to cut the pulp, and the larger the contact area, the more likely it is to deteriorate. If you just wipe it with a rag and then use it, you will "bury" more bacteria.
04
No disposable masks were worn
We usually breathe and talk with a lot of droplets, which not only increase the risk of respiratory disease transmission, but also contaminate food.
Wearing a mask properly can effectively prevent droplets from contaminating food.
A reporter once secretly visited the takeaway platform Guoche store
The sanitary situation was found to be worrisome
The time of production and storage is unknown
The fruit cuts that have been placed in the stall are not clear to us about the production and storage time. The degree of spoilage of the fruit will increase with the longer the storage time, and the food safety risk will also increase.
At present, it is summer, and the temperature in many places may have reached more than 30 °C, and 4 °C ~ 60 °C is the dangerous temperature area for food.
A 2017 study published in Foodborne Pathogens and Diseases compared the growth of salmonella and E. coli at different storage temperatures in fresh-cut cantaloupe, honeydew melon, mango, watermelon, dragon fruit, papaya and pineapple.
The results showed that Salmonella and E. coli in fresh-cut fruits did not change significantly within 6 days of storage at 5°C. When stored at 25°C, the number of these two bacteria increases by up to 4 times in a day, and the longer they are placed, the more bacteria count.
It can be seen that the probability of bacterial contamination of street fruit cuts is not low, and the longer the storage time and the higher the temperature, the higher the risk of food poisoning.
Yu Kai, deputy chief physician of the emergency department of Sun Yat-sen Memorial Hospital of Sun Yat-sen University, said:
"After cutting the fruit, it is generally not recommended to eat it after 4 hours when stored at room temperature, because it is easy to produce bacteria and bacterial infection. If it causes bacterial food poisoning, it can cause symptoms such as nausea, vomiting, diarrhea, abdominal pain, weakness, dizziness, headache, and even chills and fever. ”
It is recommended that everyone who wants to eat fruit cuts
It's best to cut it yourself
If you must buy it
Please note the following
01
Pay attention to the choice of store
If there is no clear fresh-cut operation area and cooking table in the store, and the hygienic environment is poor, try to avoid buying fruit cuts. In addition, it is not recommended to buy fruit cuts from mobile stalls where hygiene conditions cannot be guaranteed.
02
Pay attention to whether the props and cutting boards are clean
When buying fruit cuts, you should pay attention to whether the knives and cutting boards of the merchant are cleaned in time after cutting the fruit. Fruit juices are rich in sugar, and these utensils are prone to sugar and bacteria breeding.
03
Pay attention to whether the fruit is fresh or not
If you find that the color of the fruit is oxidized and black, the flesh is wilted and soft, the fruit plate is oozing juice, or smells of wine, etc., it means that the fruit itself is not very fresh or has been cut for a long time, so it is not recommended to buy it.
04
It is advisable to choose your own fruits
It is recommended to choose the fruit at the fruit store and let the store handle it on the spot, and eat it as soon as possible after purchase.
All of the above
Did everyone remember it?
