What is the rule of 5 seconds?
The 5 second rule is an informal rule known to many people around the world. Basically, the "rule" states that the running food can be picked up and eaten if removed from the floor in five seconds.
In other areas, a 5 -second rule is known as a 3 second rule, suggesting that some people may be more concerned about contamination than others. Unfortunately, in both cases, the "rule" is not an accurate measurement of potential contamination, because the food is perfectly able to pick up harmful bacteria, such as Salmonella, immediately. The first is that harmful bacteria are often invisible, which means that the apparently perfectly clean floor could actually teem with bacteria. The second is that harmful bacteria are everywhere, especially on floors, because they are monitored by shoes, legs and pets. Other substances such as a carpet may hide bacteria for weeks. Because a person never knows wklobouk can lurk on the floor, the rule of 5 seconds is indeed valid only if you haveMicroscope and some swabs at hand.
The second problem is that bacteria could wait for adherence to food. Bacteria are transmitted by direct contact and food will be dangerous in one second, let alone five if the floor hides bacteria. It is certainly true that more bacteria will be present after a long spell on the floor, but the 5 second rule does not necessarily have to be a good measure of potential food safety.
It should not be any surprise that several universities were conducted by a study of 5 second rules. They found that dry foods such as biscuits and biscuits may not be so likely to pick up bacteria after short contact, but that wet foods like ice cream are almost certain that they will be contaminated. Dry floors like wood or stone are less likely to hide bacteria than carpets, alocor no floor is completely free of bacterial guests.
In general, the rule of 5 seconds should not be observed when the food is dropped to the floor, no matter how tempting it can be. Foods that can be washed could be potentially washed and then consumed, but other foods should be thrown away because the risk of bacterial contamination is too large. While some bacteria could only cause the consumer to feel a little sick, others can lead to serious systemic infections that could be deadly. "She lived according to 5 second rules," there is no inscription that wants a tombstone.
