Can we still eat the food fallen on the floor? Someone say there is the “5 second rule”, while other people say you should absolutely not eat it.
Reliable and even less reliable studies spoke out in favor of the 5 second rule. According to it, you can safely eat the food fallen on the floor, but you need to pick it up in less than 5 seconds.
Today we are going to debunk the myth, in fact, more than one! Actually, the 5 second rule has no scientific bases. However, it is also true that leaving a piece of food on the floor for one minute will make it absorb more bacteria than one that stayed on the floor for just three seconds.
Therefore, we can say that, from a certain point of view, the 5 second rule is true. However, it depends on the type of food that falls on the floor. A dry one (such as bread, biscuits, chocolate, etc.) will absorb less bacteria than fresh foods (cheese, meat, eggs, etc.). If we want to eat them, we need to know that we can contract more easily E. coli and streptococci.
What does science say?
How does science consider the 5 second rule? Some experts actually made a research on this topic, and found out something very interesting.
According to a research published on Science Daily, the 5 second rule is not true, because the contamination can happen in less than a second. Donald Schaffner, food science expert and professor, published the results of his research on Applied and Environment Microbiology.
“We decided to research this topic because this is a widely used practice. The subject of our study might seem shallow, but we wanted the results to be backed by solid science”.
