One of the common beliefs in North America, UK, Australia, South Africa and Japan, it is safe to eat meals that have fallen to the floor.In the Russian version - "rapid uplift is not considered fallen."
five-second rule (Eng. Five-second rule) applies to food, particularly hard, such as biscuits, which fell to the ground or floor;it argues that any germs that can go to the fallen food in less than five seconds to be in such a small quantity that is easily destroyed by stomach acid, and can not cause harm to the body.
This rule is used as a suitable justification of the possibility to eat picked up the food and is generally used only in the presence of several people.For example, a person can drop the candy on the floor, but then quickly pick it up, telling friends, "five-second rule!" - And eat.
five-second rule is rarely applied in the event of a sticky products such as ice cream, meats, chewy candies moistened "jelly beans", especially if the pollution is clearly noticeable.Also, usually rarely used in case of a fall butter sandwich down.Rarely rule applies to falling food of others, however, are known and numerous exceptions.The origin of the five-second rule is unknown.
There are no official data on the practice of application of the five-second rule in the kitchens of restaurants.However, in view of the well-known cooks great hurry, it can be assumed that it is used there often enough.Although the idea of introducing rules for five seconds as the official norm in institutions catering high-end is absurd, its use, apparently, is not limited to restaurants only low standards.
Sometimes the five-second rule is found in variations usually three seconds, usually seven seconds, usually 10 or 15 seconds, usually depending on the terrain, or the value of fallen food.For example, in American college dorms typically ten seconds is often referred to as the five-second rule in the "drunken version."In public camps for boys there is a variation of the rules, "pick until dragged bugs" (eng. Get it before the bugs do).
In some cases, if expire the first 5 seconds are added to the next, and so on, until the fallen piece of food still will not be raised and eaten.
Around the world there are many idiomatic expressions associated with the risk of eating food contaminated with.Here are some examples:
contagion to the contagion will not stick.
rapid uplift is not considered fallen.
each mote in the forest - Vitaminka.
In the forest there is dirt - in the woods some vitamins.
The hike all sterile.
What fell from the student - it fell on a newspaper.
One, two, three - the germs are not logged in.
more dirt - wider muzzle.
not lie - do not sing.
O que no mata, engorda (in Portuguese: What does not kill you fertilize.)
Poco veneno, no mata.(in Spanish: Small poison can not kill.)
Min ma joqtolx, isemmen (Malta: What you do not kill, then go to greasing.)
Quel che non strozza, ingrassa (in Italian: That which does notsuffocate, will promote fattening.)
Chancho limpio nunca engorda (in Spanish: Clean the pig not zhirneet.) Dreck macht Speck (German: Dirt does fat.)
Dreck reinigt den Magen (in German: Mud cleansesstomach.)
Zand schuurt de maag (in Dutch: Sand cleans the stomach.)
study of five-second rule was carried out in 2003, a graduate of a high school Gillian Clark (Jillian Clarke) during the seven-week practice at the University of Illinois (University ofIllinois at Urbana-Champaign).
Clark and Meredith uglies (Meredith Agle), controlled study, samples were collected by swabs from floors on campus: in the laboratory, dormitory and cafeteria.The examination of the samples obtained under the microscope revealed that they do not contain significant amounts of bacteria.
At repeated the experiment were obtained the same results;This led to the conclusion that in most cases, dry floors can be safe enough to have matched with their food.
However, Clark also included plans to test the hypothesis in the case of five-second pre-known bacterial contamination of the floor.In the laboratory on smooth and rough tile flooring has been applied in a certain amount of culture E. Coli.These tiles on a different time samples placed food: pieces of biscuits and sweets "gelatin bears", which are then subjected to microscopic examination.All bacteria were detected in the samples of significant amounts after less than five seconds.Thus, the five-second rule has been scientifically disproved.
During his studies Gillian was also carried out a public opinion poll about the rule of five seconds, which revealed that 70% of women and 56% of men familiar with the rule of five seconds, and the majority were guided by this rule, when deciding to eat fallen to the floorfood.In addition, it was revealed that women typically used more frequently than men, and also the fact that the fallen biscuits and sweets are the subject of its application more frequently than broccoli or cauliflower.
Jobs Clark in 2004 was awarded the Ig Nobel Prize for Public Health.
five-second rule also appears in an episode of the series "MythBusters» (MythBusters), the channel "Discovery» (Discovery Channel).The results of the experiments conducted by them confirmed the finding Clark: The exposure time is not a factor for bacterial contamination of food;even two seconds - more than enough time for her infection.
