Is it true that food picked up quickly from the floor can be eaten?

Eating food off the floor? Dismiss! Any normal person will disdain this. But what if the product just fell to the floor and lay there for a few seconds? In such a situation, many are guided by the unwritten “rule of five seconds.” For some reason, it is believed that during this time the food simply does not have time to get contaminated or get bacteria. It must be said that this is an international rule, in our country it is used more often in the form “What is quickly lifted does not count as fallen!” But how true is this statement in reality?

The five second rule applies to food that has briefly fallen to the floor. According to him, even if some microbes get on the food in a few seconds, there will be so few of them that the gastric juice can easily cope with them. And the food will retain its qualities and will not be harmful. This rule is somehow connected with numerous idioms that have formed in different parts of the planet:

  • What fell on the student fell on the newspaper.
  • In the forest, every speck is a vitamin.
  • Everything is sterile in nature!
  • The microbe is not a fool, it will not climb into the dirt!
  • The dirt cleanses the stomach.
  • If you don’t roll around, you don’t eat.

… etc.

Does the Five Seconds Rule Work?

But scientists do not look at this phenomenon so cheerfully, showing their inherent meticulousness. So, in 2003, high school graduate Gillian Clark, practicing at the University of Illinois, decided to test the famous rule. For the experiment, samples were taken from the floor of the laboratory, dormitory, cafe. It turned out that the obtained samples did not contain a sufficient number of harmful bacteria. And a second test confirmed this information. Thus, dry floors are relatively safe when eating food that has fallen on them.

The student went further and decided to check the floor for bacterial contamination. On the smooth and rough surface, the researchers applied E. coli. And then they put food samples on the floor. Just a few seconds of contact with the surface was enough for the bacteria to migrate to the food. So the five-second rule turned out to be overturned.

But the study was not only about microbiology, but also about sociology. In the course of the survey, it turned out that 70% of women and 56% of men fully trust this rule and are ready to eat food that has fallen briefly on the floor. Not only do women believe more in the stereotype, but it also applies more often to sweets and cookies than to cauliflower or broccoli. Gillian Clarke’s work did not go unnoticed by the public, but was awarded the comic Shnobel Prize in Healthcare.

Can I eat food that has been on the floor for less than 5 seconds?

We decided to check the five-second rule and the Mythbusters from the Discovery Channel. Their findings generally confirmed Clarke’s findings. The time of contact with the surface has little effect on the degree of bacterial contamination; just a couple of seconds is enough for food to spoil.

But this issue still continues to concern the public. In 2016, another study was carried out. The specialists of the University of New Jersey shared their findings in the scientific publication “Applied and Environmental Microbiology”. Unsurprisingly, the five-second rule was again proven wrong. Nevertheless, the scientists emphasized that the speed of bacteria transfer to the fallen food still depends on its type, as well as on the type of surface. So in some combinations, food that has fallen to the ground can still be considered relatively harmless.

But it is perhaps too early to put an end to this interesting question. Indeed, in 2017, Professor Anthony Hilton from the University of Birmingham said that, of course, you should not eat food that has fallen on the floor if dirt or specks are clearly visible on it. But if there is no visible contamination on the food, then the chance of harmful bacteria getting into it in a few seconds is very small.

Supporters and opponents of this rule, as can be seen from the research, were divided into two considerable camps. At the same time, what is interesting, both those and others can rely on quite scientific research as an argument.

Whether your phone is picked up when you sleep: how to find out

by

[ad_1]

Well, a lot of confidential and valuable information is stored in a modern smartphone. No one wants his phone to fall into the hands of someone else. That is why users install protection in the form of passwords or pattern keys on their devices.

After all, information on the phone is often more expensive than the phone itself. And we are not talking about the moral inconvenience due to data loss. Smartphone is our key to bank accounts, payment systems, online shopping. I don’t even want to imagine what an attacker can do on your behalf. And if someone besides you knows the password for your phone, then all responsibility for such gullibility lies solely with the owner. But the iPhone lets you know that someone picked it up and took some action with it.

First, you need to understand that, in principle, giving access to your iPhone is not a good idea, even if it is about your spouse or children. And here the question is not even that a person close to you can find something on the phone that he is not meant to know.

You should understand that an access code is a tool not only for unlocking a phone, but also for performing quite important actions later. This includes confirmation of payments in the App Store and iTunes, online and offline purchases in Apple Pay.

How can Screen Time help?

If such a situation has already developed, and other people can use your iPhone by adding their fingerprints or faces to the phone base, then the owner can at least check when his phone fell into the hands of other people. Let’s make a reservation right away that it makes no sense to study the list of applications running in the background. For starters, few people remember which programs were open the last time they used their smartphone. And the person who took your iPhone in hand could easily have just closed all the software used, clearing the memory.

In such a situation, the “Screen Time” function will be great. It will track unauthorized activity of other users. Of course, first, this function must be activated so that it later records everything that happens to your iPhone. For this:

1. In the appendix “Settings“Find the item”Screen time“.

2. In the window that appears at the top, click on the item “Enable Screen Time“.

3. On the next screen, tap Farther, and then This is my iPhone…

Again, to find out if someone has used your iPhone, You must enable Screen Time in advance… This is the only way to distinguish your own activity from outsiders. And here are the required next steps:

1. If you believe that someone was gaining access to your smartphone, then on the iPhone go to Settings → Screen time…

2. In this menu, click on the line “See all activity“. Then open the “Day” tab, there it will be easier for you to consider extraneous activity.

3. A screen opens with a weekly or daily view of iPhone usage. Select the required day. Below in the section Often used a list of the most used applications will appear.

4. By clicking on a specific application, you can get more detailed information about the time of its use. The numbers at the bottom of the grid are tied to the time of day. The scale is evenly divided – 00, 06, 12 and 18, this is exactly the hours at which this or that activity was noted. If you click on the scale, a more specific time value will appear.

It will be most effective to study the breaks between activities. Each such pause means that the user has stopped working with his iPhone, postponing it or going to bed. If some activity soon appeared, then someone clearly picked up your smartphone and began to work with it.

How do you know if someone is using your iPhone?

You can build on the time of work. So, you can know for sure that in the period from 11 pm to 7 am you slept. If at this time your iPhone was working with some applications: social networks, instant messengers, then this should make the owner think. Then it is worth checking another time. If similar matches are found there, then an unauthorized person may be suspected of using your iPhone.

What to do in such a situation is clear, there are not so many options here. The easiest and most logical way is to ask your partner, friend or child not to use your iPhone. True, in life, such requests are often simply ignored. Then you will have to act more decisively. You can simply set a new access password, making it harder than the previous one (you didn’t use the year or date of birth, did you?). A more serious step is to remove an alternative fingerprint or face from the database. As a result, no one from the nearest circle will be able to access your smartphone.
